Prophylaxis and exclusion : compulsory isolation of Hansen s disease patients in

This article aims to retrieve the history of Hansens disease in Brazil, analyzing the medical thinking of the time and the shaping of health policies that permitted the implementation, in São Paulo, of a prophylactic policy of compulsory exclusion for all Hansens disease patients. It also analyzes how the structuring and implementation of this policy led to a São Paulo model that strongly influenced the rest of the country. It addresses the creation of the states network of leper colonies, their characteristics and the emergence of a veritable parallel state that endured until 1967, with complete disregard of all the changes taking place in both national and international prophylactic policymaking.


The São Paulo model and isolationist policy
The stages of implementing compulsory isolation in São Paulo encompassed various prophylactic approaches that in some way reflect the concerns of the national and international scientific community and the methods adopted in other endemic countries.The preventative policy that would culminate in the São Paulo model was structured gradually.While isolation was selective in some Brazilian states, in São Paulo it was compulsory for all people diagnosed with Hansens disease and only in São Paulo was enough power and funding available to implement such a policy.The São Paulo model was also influenced by the eugenic thinking of the start of the century and its modus operandi was affected by both the Norwegian model that preached the exclusion of the sick and by Brazils own campanhista model that proposed strict, almost military-like strategies to combat diseases.
The various theories for dealing with leprosy in Brazil at the start of the 20th century were reflected in both medical thinking and proposed public health policies.In São Paulo, the discussions were basically held between two main camps.In the first were the humanitarians: they championed a reform of the existing small leper colonies and the construction of others in the state to meet the demands of each region; they called for selective isolation, only for those with contagious forms of leprosy and with open lesions.In other words, only those patients who represented a contamination threat would be removed from society.It is worth pointing out here the existence of different clinical forms of Hansens disease: indeterminate, tuberculoid, dimorphous and lepromatous; and only the latter two are contagious. 5The advocates of the humanitarian approach also judged that patients who were unable to remain isolated at home should also be interned, with the remainder receiving outpatient treatment.This selective policy was at the time given the name humanitarian isolation and one of its chief advocates was Emílio Ribas, a leading authority in the area of public health. 6n the other camp were the isolationists, who proposed the following plan: construction of large isolation units in certain areas of the state, closure of the existing colonies, banning outpatient treatment, compulsory internment for all leprosy patients, regardless of socio-economic position, sex, age group or whether the clinical form of the disease was contagious.Among the defenders of this way of thinking was Francisco Sales Gomes, director of the São Paulo Leprosy Prophylaxis Service from 1930 to 1945 and, as such, responsible for the implementation of the São Paulo model.Within this second camp there was an even more radical group that proposed that Hansens disease patients should be sequested in areas of difficult geographical access, claiming this would make it easier to control the disease and harder for patients to escape.These radicals endorsed insular isolation or the creation of a municipality where the sick could be secluded.A key figure from this group, which did not manage to see its ideas put into effect, was the architect Abelardo Caiuby, designer of the projects to construct the Santo Ângelo leper colony, whose architectural conception influenced other colonies.The ideas put forward by Caiuby echo the positions defended by leading names in the Brazilian health system, such as Arthur Neiva, Heráclides Neither the conditions nor the space existed to house all the sick, in virtue of the growth of the Hansens disease endemic in São Paulo and the precarious situation at the regional leper colonies.There were several small regional colonies inland in the state, while in São Paulo city there was only one, Guapira, which was set up and run by the Santa Casa da Misericórdia medical institution.Each colony was run differently, although one thing they all had in common was a lack of resources.Many offered no more than a place to live and did not have staff to care for the patients, nor medicines.Aside from these colonies, there also existed itinerant leper camps alongside highways.Although the legal means was available to intern lepers from these camps, it did not occur as a result of the inexistence of colonies in sufficient number and size to house so many people.
The controversy surrounding how best to address this situation involved the state, official medical services, scientific societies, charities, civil society groups and the press. 9Several issues had to be analyzed and discussed: location and size of the colonies, the ideal number of people per colony and whether to intern all those infected or just those with contagious forms of the disease.The fear that the proximity of the colonies or the concentration of patients would contaminate surrounding areas prompted interminable discussions on the technical solutions to adopt: wind direction, directional flow of water, means of supply, drainage, etc.These discussions, in general, involved not only leprologists and sanitary engineers, but also included the daily press at the time.The only consensus among these different groups was the removal of the sick from society.
This situation led municipal governments from inland São Paulo to convene the Municipalities Convention to discuss the establishment of joint measures to choose the locations for regional leper colonies and the means of funding them.The official medical service 10 mediated the meetings and, by using a series of strategies, managed to extract from the hands of leprosy aid associations and municipal governments the management of the funding for the leper colonies and the construction that had already begun.
As a consequence, a network comprised of five establishments, four colonies and one sanatorium, was built within a short space of time, and it was run entirely by the State.Consequently, the isolation process was implemented in precisely the way the medical service wanted it done.

Structuring the prophylactic service
At the end of the 19 th century and during the first few decades of the 20 th century, São Paulo witnessed a transformation resulting from the expansion of the coffee economy and the move towards industrialization.New demands arose both in the countryside and in the city, prompting a reform of the sanitary services in order to extend treatment to the countryside, in newly cultivated regions farther west and the old regions in decline, and to meet the new demands in the city resulting from industrialization.The state government was urged to adopt policy capable of promoting and protecting health, even if this required coercive measures.Due to this pressure, the state took steps improve sanitation in cities and the countryside and to combat endemics and epidemics.Many of these measures preceded those adopted by the federal government and by other states, as only São Paulo had resources enough to apply them.
Despite São Paulos precedence, the development of its isolationist model was not entirely independent and it had to observe federal regulations, although disagreements between state and federal authorities at the time allowed Brazils states to overlook some the stipulated rules and/or the legislation in force.
The transformations that occurred in Brazilian health services after 1920, particularly the founding of the National Health Department, had a direct impact on Hansens disease policy, notably due to the creation of the Leprosy Prophylaxis Inspectorate and prophylaxis regulations. 11The former was intended to oversee preventative programs on a nationwide level, although it was PROPHYLAXIS AND EXCLUSION prohibited from implementing the programs in virtue of the autonomy of the states.As a result of this, agreements were signed whereby state governments consented to respect federal sanitary legislation and ensure it was observed in their jurisdiction.All Brazils states signed the agreements, with the exception of São Paulo. 12 The states independent position now enabled it to develop its own prophylactic policy.The growth of the endemic in São Paulo and the ensuing pressure prompted the Sanitary Services Department to create, in 1924, the Leprosy Prophylaxis Service, which was state-level, although very similar to the national service. 13The following year, on July 19, 1925, the Service was remodeled and renamed as the Leprosy Prophylaxis Inspectorate (IPL) 14 and history illustrates its political clout in determining policy.Depending on the members of the board at any given time, the states policy on isolation would vary.The Sanitary Service director and state governor also had a direct influence on the appointment or dismissal of the IPLs chief inspector and on the procedures for constructing the leper colonies. 15fter the 1930 Revolution that gave rise to the Getúlio Vargas Era, the faction that ladvocated the compulsory isolation of Hansens disease patients in São Paulo were now in a position to assume power, a process that can be illustrated by the number of new appointments, dismissals and exonerations during the years of the New State.In this political period, power over many health programs and services in São Paulo was centralized, which enabled exceptional measures to be taken, even in relation to diseases that were targeted for confinement and isolation tuberculosis and Hansens disease.The same thing occurred in the area of mental health.It is clear in these cases that authoritarian measures began to be accepted and, in some cases, even welcomed and were seen to be essential in the administration of prophylactic policy.This situation also made it possible to appoint medical professionals such as Francisco de Sales Gomes Júnior, a name that is closely associated with the Getúlio Vargas stage of combating leprosy. 16is administration clearly illustrates the authoritarianism that characterized São Paulo health policy in the 1930s and 1940s.Sales Gomes was a fierce opponent of outpatient treatment and defended compulsory isolation for all Hansens disease patients.His rise to the head of the Leprosy Prophylaxis Service was purely political.The fact that he was a surgeon and had never before worked with the disease did not prevent him from being appointed and he remained in charge until the end of the Vargas Era.His administration was marked by authoritarianism and it was the time when the Leprosy Prophylaxis Service was at the peak of its power.
When he took over at the Leprosy Prophylaxis Inspectorate, as it was then called, Sales Gomes used the existing structure and some previously organized programs, while at the same time making certain alterations to enable him to implement mass compulsory isolation, and, in very few years, he managed to establish the states network of leper colonies.A structure was implemented that was deemed exemplary and was kept working by a regime of force that required, and received, generous political backing.The growing importance of the Leprosy Prophylaxis Inspectorate paved the way for its transformation, in 1935, into the Leprosy Prophylaxis Department (DPL).It had characteristics that differentiated it from all other health departments: a sizable budget, its own staff and its independence from the State Health Department.In fact, it took very little time for DPL decisions to cease being made within the sphere of the Health Department, instead being discussed directly with the state governor.
Sales Gomes implemented a system whereby all decisions were centralized into the hands of the director.Various strategies were adopted to remove from office members who opposed compulsory isolation of the sick.Courses and training began to be offered to medical students and young doctors to recruit only those who subscribed to the official prophylactic policy, which is how the consistency of medical thinking in the São Paulo Prophylaxis Service was achieved.

Implementation of the São Paulo model
Beginning in the mid-1920s, a process takes shape that gave rise to the São Paulo prophylactic model, a process characterized by a modification of legislation, regulation of the isolation policy and a structuring of the official services according to new directives.While São Paulo advocated compulsory isolation of all Hansens disease patients, other states opted for more lenient prophylactic models that were more in line with what was being recommended by international congresses.Rio de Janeiro, for example, when it was still Brazils capital city, only interned contagious cases, while patients with noncontagious forms and those cured by treatment were free to live in society and receive outpatient treatment.
From an operational point of view, São Paulo implemented a hierarchization and centralization of administrative functions with decision-making concentrated in the hands of the director of the Leprosy Prophylaxis Service.The headquarters was in the capital, but the director was able to intervene quickly in inland São Paulo state through his regional branches.These were assigned to implementing the measures to combat Hansens disease within their jurisdictions and were authorized to administer punitive action whenever deemed necessary. 17or this model to consolidate, specific legislation permitting the use of the planned measures was essential.Law no.2,416 of 12/31/1929, sanctioned by Governor Júlio Prestes, revoked existing legislation 18 and enabled the new policy to be implemented in the state.This legal text was of extreme importance, as it shaped the basis of the states new prophylactic practices.It was divided into two parts: the first, called Leprosy prophylaxis, fully regulated the lives of patients, from the moment of the diagnosis to their death, and it even regulated the lives of their associates.The second part, Organization and staff, dealt with the internal organization of the Leprosy Prophylaxis Service, its operational structure, duties and jurisdiction.Over the years, the law suffered some minor alterations, making it even more stringent.Immediate notification of all cases became compulsory and only DPL doctors were authorized to treat leprosy patients.All other medical staff were expressly forbidden from treating their patients once the diagnosis had been made and they could be punished for doing so.This policy was designed to both centralize patient data into a single government institution and also to oblige the sick to seek their own internment in order to gain access to medicine.
The centralization of data on patients was essential to assume full control of the situation, which is why the registration of patients and their associates was obligatory, storing information and background reports in a central file that was created in 1925.This file contained details of the evolution of the disease in each diagnosed patient and personal data, family information and current and former addresses.Over the years, the organization of the file was improved, speeding up access to the information.This provided the DPL with information on the location, forms of treatment, track record and data on the day-today life of every patient interned in any of São Paulo states leper colonies.
The DPL collected data on the families and, sometimes, the close friends of patients for epidemiological reasons.Claiming that these people could easily have been infected, it labeled them as associates and kept a file on them.These associates were obliged to present themselves for regular testing and their information was kept in a specific file.They were allowed to live in their homes, but they were kept under strict vigilance by the DPL. 19.This strategy enabled the swift location and capture of patients who managed to escape from the leper colonies or associates who failed to turn up for their tests.The existence of a thorough dossier on each of the interns together with information on their relatives allowed officials to monitor all those associated with the world of Hansens disease and created a system of control and vigilance never before seen.
In short, the model set up in the name of prophylaxis called for immediate, compulsory removal of patients from society, deprived them of their most basic rights and segregated them in colonies where they were constantly watched, controlled and governed by specific laws.Once they entered this world, they were kept on file and given a number their file number that they would keep for the rest of their lives.The lives of their relatives, listed as associates, were also monitored by the Leprosy Prophylaxis Department.The São Paulo model was based on the notorious trinity of leper colony, dispensary and prevention center.Each of these institutions had its own distinct, although complementary, roles.The colony was most important, as it insulated the sick.The job of the dispensary was to locate new patients and send them for isolation, document the cases and regularly test the associates while ensuring that they did not miss their appointments (a special vehicle used to go out in search of the associates, causing problems in their personal lives and at work).The role of the prevention center, meanwhile, was to provide shelter for the healthy children of patients and all the children born in the leper colonies and keep them under close observation.
The establishment of the São Paulo network of colonies, between 1928 and 1933, prompted mass internment.Prophylaxis Service teams scoured the whole state and the press reported on progress combating the disease as if it were an ongoing battle.The population was encouraged to participate by informing on suspicious cases.Both the capital and inland São Paulo were investigated by DPL employees who drove around the state in special vehicles taking into custody patient from their houses, camps and from old small colonies.These regional colonies were closed down, the camps destroyed and private houses burned to the ground.The sick were rounded up, taken to strategic points and, usually, placed in special train carriages and taken to the site of isolation.
The new large leper colonies soon filled up and, within a period of just ten years, the DPL had become an extremely powerful and organized outfit.It became one of the prides of São Paulo, supported by the government and praised by both the press and the majority of civil society.
The press reported on each act of the DPL as if it were another victory in the war against the plague of leprosy and conduct that could otherwise have been considered to be an act of violence against the sick were presented as proof of the governments determination to do away with the insidious disease.The fact that Brazil was living under the Getúlio Vargas dictatorship, whose Press and Propaganda Department harshly censured the press, made it easy to adopt authoritarian and repressive measures against it opponents.
In short, the 1930s are of special importance in the history of Hansens disease in virtue of the implementation of a specific prophylactic model The preventative services extended their sphere of influence, large leper colonies were built and mass internment was introduced.The measures in place at this point would steer São Paulos policy for fighting the disease until the end of the 1960s.

PROPHYLAXIS AND EXCLUSION
The structuring of a world apart The introduction of the isolationist policy in São Paulo practically created a separate world, with the full backing of the government and blessing of most of society.If we look at the discourse and official documents of the time, we may observe that the chief justifications for this model were: a) preservation of society; the presence of patients in society was portrayed as a danger of contagion; b) epidemiological control; DPL leprologists believed that leprosy would be wiped out within a generation as long as all those infected were removed from society; c) well being of the patient; it claimed that, given the stigma associated with the disease, lepers would feel more comfortable living among themselves, where they would not be the target of discrimination.
All the leper colonies in the network followed an architectural standard in order to make it easier to control the patients and, at the same time, monitor the life of each one.The colonies all had a strict division of space.Each one had three separate zones: the healthy, the intermediate and the sick zones, which were also referred to as clean, neutral and contagious.The healthy zone contained: the entrance, the power generator, water tanks, storehouses, garages, administration offices, management and other services necessary for the running of the colony.It also contained the houses of the director, the doctors and the administrative staff, the size and style depending on the importance of the profession.The intermediate zone was located between the healthy and sick zones.It contained the main pavilion, the site for checking visitors and the visiting room. 20The sick zone, representing the colony itself, contained: the hospital, the clinical pavilion, the dormitories (Carvilles), houses for the married patients, psychiatric ward, prison, social club and church, in addition to the land for cultivating and keeping animals.The sick zone was rigorously separated from the healthy zone.At the Cocais leper colony, for example, a 300-meter buffer zone separated one section from another.The division of the two was clearly marked and there was even a gate and an entrance hall.Only very few people were authorized to cross the dividing line and only on very rare occasions were patients allowed to cross.
The style, size and internal distribution of the buildings clearly illustrate how the Prophylactic Service wanted the day-to-day life organized inside the colony; in other words, how the exclusion zone was organized.Over the years, buildings were reformed or new ones were constructed, although the structure of the sick zone always stayed the same.
Official documentation of the time provides important information on the construction of the colonies.One such publication from 1936 (Revista Brasileira de Leprologia, pp.95-105), refers to the Pirapitingui leper colony and enables us to verify the types of installations, their sizes and their uses.a) Hospital complex comprised of: hospital with two wards with twenty beds each and another eight rooms for isolation; pavilions, a type of hospital/dormitory where incapacitated patients resided; five consultation rooms and a dental surgery; patients kitchens for the hospital and the Carvilles, one for the mens pavilions and another for the womens.b) 54 groups of semi-detached houses, each one with two bedrooms, veranda, kitchen and bathroom, built along two avenues.c) Detached houses: three groups of detached houses for the chaplain, mayor and teacher.d) Wooden houses: the colonys first constructions, before the brick houses, each with four bedrooms.e) Ten Carvilles (accommodations for unmarried patients), four for women and six for men; each Carville having 11 bedrooms.f) Social club: built with private money, it contained a cinema, classrooms, a reading room, a library, a games room, a billiard table, a bar and the office of the colonys charity fund (Caixa Beneficente). 21g) One Catholic and one Protestant church.h) Restaurant built by the Caixa Beneficente, for the wealthier patients, that offered a wider variety of food.i) The psychiatric ward and the prison were located in the same building, the psychiatric ward on one side and the prison on the other.
As a result of the strict division of the healthy and sick zones, all tasks were carried out separately in each of the zones.The administrator of the former had his own staff working in the washroom, bakery, kitchen, butcher, conservation of buildings and vehicles, raising livestock, gardening and reforestation.These same tasks were carried out by different staff in the sick zone, under the control of the mayor, 22 who had his own staff to carry out these services.
As for the clinical services provided at the leper colonies, the DPL divided them into two sections, one healthy and another sick, both controlled by the director.The former was comprised basically of the medical staff, the latter by the nursing staff, who were all patients. 23It is worth emphasizing here that until 1967 all nursing services were carried out only by patients, who rarely received courses or training to perform these services. 24ach leper colony was like a small town, with its own technical and bureaucratic structure that answered to the colonys director, who in turn answered to the director of the DPL.Just like in any town, the colonies had the power to police and punish residents who broke the rules.The police officer, a patient appointed by the director, controlled the so-called Sanitary Guard, also formed by patients, and the prison, where those who broke the internal rules of the colony were detained.

PROPHYLAXIS AND EXCLUSION
All disobedience of the rules was punishable and the most serious infringement was attempted escape.Some of the colonies had their own prisons, which also held common criminals who had been legally condemned in the real world but who suffered from Hansens disease and were therefore unable to be detained in federal penitentiaries.But the prisons were also used to punish patients who broke the rules of the colony.Psychiatric wards were also built at some colonies to house mental patients who had Hansens disease.
The goal was to make each colony as self-sufficient as possible, which explained the presence of brickyards, repair shops, factories and agricultural activities.These activities were significantly important, as they kept the patients occupied and provided a small profit for the colony.
The leisure activities at the colonies were emphasized by the press at the time.Practically all the leisure activities sports fields, the social club building that contained the library, games room, cinema and theater were built from donations made by individuals, groups or associations.
The publications of the time, particularly newspapers, gave broad coverage of the leisure activities in the colonies.The reports portrayed a view that was at the same time humanitarian and practical: seeing as compulsory isolation was established for the good of society, Hansens disease patients ought to be compensated in some way for their forced exclusion from the social and family environment.But they also argued that there would be fewer escapes if patients felt more satisfied inside the colonies.

The role of private initiative
Both individuals and organized groups from civil society mobilized behind the Hansens disease cause, particularly during the 1920s and 1930s.This type of support was very important for the official medical service and it was encouraged in virtue of the funds that were raised.The funds paid for the construction of leper colonies such as Santo Ângelo and Cocais that, once completed, were incorporated into the State.It also enabled many improvements to be made at the colonies.Various projects and campaigns to raise funds were established, namely to improve the living conditions for the patients.Thanks to individual and group initiatives, many of the community lodgings for patients and houses for married patients were built.The newly-raised funds paid for the construction of new buildings and the renovation of the existing ones, such as the erection of workshops and facilities for leisure activities.The role of these organized groups was not limited to charity work or projects to assist the physical comfort of patients.They also concerned themselves with scientific research and the purchase of medicine.There is a case in which the Society for the Assistance of the Leprous sent away for chalmoogra seeds from India and a ton of raw oil in order to set up its own factory to manufacture medicine for the treatment of those afflicted by leprosy 25  (Tibiriçá, 1934, p. 31).
With the passage of time and the centralization of power, the DPL began to consider charitable contributions as external interference in the leper colonies.However, while it attempted to forestall the benefactors and/or the organized associations, the DPL did not want to dispense altogether with this type of collaboration, given its capacity to raise funds.A very delicate, at times conflicting, relationship therefore ensued between the private organizations and the Prophylactic Service, which was always on the lookout for sources of income but at the same time suspicious of any outside influence.
The way found to neutralize external interference was to set up intermediaries, or the Caixas Beneficentes.All donations would now have to be made to this institution, which would decide where and when to spend it.As a result, the Prophylactic Service ended up administering both the official budget and donated funds for the colonies.

The construction of the network of colonies
The isolation network in São Paulo, comprised of four large leper colonies, one sanatorium and two prevention centers, was considered an example to be followed and was visited by leprologists from all over the world, particularly those from Latin America.
The engineers that planned the first colony were influenced by some of the architectural ideas from other countries, such as the communal pavilions for housing patients used in the Carville leper colony, in the United States.The original idea was to build four large leper colonies in inland São Paulo, each with the capacity to hold around seven hundred interns.Plans also included the construction of a sanatorium for patients with non-contagious forms of the disease.This would be located nearer the capital to facilitate study and research on the disease.However, the spread of the endemic, coupled with the obsession that drove the isolation policy, meant that the capacity of each colony had to be expanded and that overcrowding was a constant problem during the period of compulsory isolation.
The choice of the site of each colony took into account the number of infected people in the region and other pertinent factors about the land: salubriousness, water supply and distance from urban areas.The authorities realized that the people to be interned would be a heterogeneous group, because Hansens disease affects people of all social classes, although more so the lower income population.For this PROPHYLAXIS AND EXCLUSION Aerial view of the Santo Ângelo leper colony.
reason, the project had to anticipate communal living for long periods of time, possibly a whole lifetime, for very different people.Before constructing the colonies, therefore, the Sanitary Service held meetings with town councils from inland São Paulo and with organized groups from civil society.
The leper colonies were designed to become units of production and eventually self-sufficient.As a result, it was necessary to buy large rural properties far from urban centers.This stage presented some difficulties because, while society approved of the exclusion measures, residents and property owners from the chosen regions protested against the presence of a leprosery in the area.The population even threatened to burn the buildings that were being erected, forcing the official medical service to seek police protection for the patients. 26rom 1931, when Salles Gomes took office, construction work to expand the network of colonies was accelerated.The urgency of the mass isolation policy was reflected in the speed of the building work.It was thought that once the isolation policy was in place, funding would be forthcoming to complete the projects.All that will come later, Salles Gomes said, we will have the funding if enough patients are interned. 27o two leper colonies had the same beginnings.The Santo Ângelo colony was planned and built by Santa Casa da Misericórdia, only to be taken over afterwards by the State.The installations of the Padre Bento sanatorium already existed when the property was bought and they were reformed and adapted to the new requirements.The Pirapitingui, Aimorés and Cocais colonies were built by the Municipalities Commission and the help of private initiative.Some of them, as we will later see, only started to be administered by the State after construction was completed.In addition to these establishments, a prevention center was also built in Jacareí that housed the healthy children of Hansens disease patients (Monteiro,  1998, pp.3-26).
The five colonies set up in different points in the state were, in theory, responsible for the internment of the sick from a predetermined region.Although each of the units was part of the same project, had the same objectives and answered to the same board, little by little and for varying reasons each one acquired its own character.

The Santo Ângelo colony
The Santo Ângelo colony was built in the municipality of Mogi das Cruzes by the Santa Casa da Misericórdia, which managed to unite the efforts of various groups and associations, namely the Association for the Protection of Morpheans [Lepers], the Catholic Womens League, the Archdiocese of São Paulo and other religious groups.Supervising the construction of the project were the Sanitary Service director, Dr. Emílio Ribas, and the author of the National Sanitary Code, Dr. Artur Neiva (Ribas, 1917).
The architectural project idealized and approved by the Sanitary Service was organized in such a way that those sequested in the colony could spend the rest of their lives there.This colony became a reference for the construction of other colonies in São Paulo and even in the rest of the country (Caiuby, 1918).
The buildings were planned to permit the separation of patients by sex, age and health condition.It was designed to become selfsufficient, containing land for cultivation and grazing livestock.The plans were so ambitious that it covered 348 alqueires [one alqueire in São Paulo is 24,200m 2 ] and required a sizable budget.
An analysis of Santo Ângelo illustrates that the architecture played an important role in the organization of mechanisms to facilitate the identification, supervision and guarding of the interned patients.The divisions in the colony, its walls and buildings were planned in such a way to make it easier to control the behavior of patients.The planning and construction spread the vision of how an isolated world should be structured, in all its complexity, including relations of hierarchy, discipline, labor and morality.Shortly after its inauguration, the administration of Santo Ângelo was taken over by the Leprosy Prophylaxis Inspectorate and became part of the states network of colonies.

PROPHYLAXIS AND EXCLUSION
The Pirapitingui colony Pirapitingui emerged from an agreement between 48 municipalities from the central and southern part of the state to house the sick from their area.These municipalities met for the first time in 1929 and agreed to free up 5% of their income for the construction of the colony.To these funds were added private donations.
The Pirapitingui colony was built along the Sorocaba-Itu highway, 22 kilometers from Sorocaba and 14 kilometers from Itu. Access was via the Sorocabana railroad, and the Pirapitingui station was five kilometers from the colony.A property with 136-alqueires was purchased in order to build the colony and, little by little, the surrounding land was also bought, increasing its size to around six hundred alqueires.
Due to the mass internment policy introduced in the state, this colony was inaugurated in 1931, when it was still being completed and had just sixty wooden lodgings, enough to house 456 patients (Maurano, 1939,  v.__ , p. 177).The other installations were completed when the colony was already functioning.
The rapid rate of construction can be verified by the growing number of interns.In 1934, two and a half years after its inauguration, the colony had 178 houses for married patients, ten pavilions for unmarried patients, two infirmaries with eighty beds each and a prison.In the same year, it has 1,243 interns: 754 men, 427 women, 32 boys and thirty girls.Five years later, in 1939, two more pavilions were erected with the capacity for another eighty beds each and five more houses (Diário Carioca, 1939).A pavilion was also built for Hansens disease patients with tuberculosis with funds from the Ministry of Education and Health (Diário da Noite, 1939).

Site of the Pirapitingui colony
Entrance to Cocais colony.
Pirapitingui, just like the other colonies, was like a small town, with several types of workshops, minor industries and agricultural activities.It also contained services and installations that were not found in all colonies, such as a cemetery, prison and psychiatric ward.The social club building had a dance hall, library and a cinema big enough to hold six hundred people (Folha da Noite, 1934).
The religious requirements were the object of attention right from the start.A catholic church similar in size to one of the cathedrals from an average inland state town was built in 1936 by Caixa Beneficente with donated money.Later in the same year, a protestant church was also built.
Pirapitingui stood out from the other colonies in virtue of its size and the number of interns.According to interviews we conducted, patients from other colonies dreaded being transferred to Pirapitingui because of the inferior conditions.

The Cocais colony
This colony had a similar outset to Pirapitingui.It was built to house patients from 36 municipalities.The first meeting was held in 1927 and each one agreed to reserve 10% of their annual revenues to build the project.With this money and private donations, an area of three hundred alqueires was purchased in the municipality of Casa Branca, where the colony was built (Folha da Noite, 1937).
The mens and womens pavilions, called Carvilles, and 46 houses for married patients were the first structures to be built, almost entirely from donations from individuals and charities.The colony was inaugurated in April 1932, when the first patients started to arrive.
The Cocais leper colony was considered to be the worst place to be interned.This was due to a series of factors, such as the distance from the capital, the large number of interns and the small number of medical staff.The Official Service medical staff came to refer to the colony as Siberia, because it operated almost like a place of exile, where patients and staff alike were sent to be punished.Of all the states colonies, Cocais was the one with the highest rate of escape attempts.

The Aimorés colony
This colony was planned to intern patients from 64 municipalities that, in 1927, agreed to spend 10% of their annual revenues to finance the construction.Work began in early 1930 on a rural property of four hundred alqueires and it was inaugurated on April 13, 1933, with 317 patients.It was initially planned to have one thousand beds, but this soon proved to be insufficient as only four years after it opened, it already had 1,435 patients, or 60% overcrowding.Extension work was done, to increase capacity to two thousands beds. 28ust like the other colonies, Aimorés obtained its own sports facilities, on May 1, 1943.The DPL considered Aimorés a model colony and it was visited by leading figures, notably politicians and leprologists passing through São Paulo.For this reason, the DPL went to greater lengths to maintain order and good presentation at the colony.
In 1944, a propaganda film was made on São Paulos Hansens disease treatment and prevention policy, which would be distributed to the four corners of Brazil (Correio Noroeste, 1944).The colony Aerial view of the Aimorés colony.
is presented as a type of prophylactic paradise, with images specially selected to serve the propaganda requirements of the DPL.Internationally, experts were already starting to question the merit of segregation, and this film was made to justify the São Paulo model.

The Padre Bento sanatorium
It was located only 20km from the city of São Paulo, in Guarulhos.To house the sanatorium, the government purchased an old psychiatric hospital that was located with easy access to both the highway and the railroad.
The sanatorium was inaugurated on June 5, 1931, with 83 patients.It started functioning with only the existing installations a building for hospital patients and another for administration, but within a space of few years, it too was transformed into a small town.The arrangement of its buildings observed the same architectural and urbanistic planning as the leper colonies, although on a smaller scale than the other facilities: just 23 alqueires.
Only patients with non-contagious clinical forms of leprosy and those who were not in the advanced stages of the disease were interned in Padre Bento, while its patients whose condition deteriorated were transferred to one of the four colonies in inland São Paulo.From our research, however, we have observed that these rules of internment could be bent in accordance with external interests, via letters of recommendation or requests from politicians, that were usually accepted by the DPL board.This meant that Padre Bento became a privileged location compared to the other colonies.
The campaigns to obtain funding for the Padre Bento center involved the elite of São Paulo society and they were often sponsored by associations such as the Rotary Club.It was with these funds that new hospital wards, a dental surgery, pavilion for doctors, social club, theater, church, leisure park, sports stadium and even a small zoo were built.Much of the money was spent on furnishing the buildings earmarked for leisure activities.Photographs from the time illustrate the care taken with the decoration and the luxury of the interiors.However, not all patients interned in the center were given access to these privileges.
The proximity of the sanatorium to the capital was, from the start, the main reason to use it as a research center and for training doctors in leprology.The medical team at Padre Bento was comprised of class of elite doctors that was not changed for decades.Padre Bento is one of the largest therapeutic and clinical research centers of any country in the world (Diário da Noite, 1941).Phrases like this one, reported by the press, illustrate the vision of this isolation center in its time.
The interest of its director, Lauro de Souza Lima, in pediatric leprosy meant a large number of children were sent there and the particular research being carried out at any given time determined the method of selecting patients for the facility and as a result, these methods varied.In virtue of this, many children even those with parents interned at other facilities or those with contagious forms of the disease ended up being housed in Padre Bento.It became a type of showcase, where distinguished visitors such as politicians, scientists and journalists were taken.Generally, they only visited the healthy zone without adventuring into the area set aside for the sick.
The national network of colonies While São Paulo introduced mass internment in the 1930s with a hefty investment and unlimited government support, internment in other states in the country occurred more slowly.This is clearly illustrated when comparing the number of leper colonies and the number of internments in each of the Brazilian states.
These data do not necessarily mean that regions with higher numbers of internments also had higher prevalence of the disease.We know that Hansens disease in São Paulo state was highly endemic since colonial times and the problem was compounded at the end of the 19 th century and during the 20 th century when economic growth attracted immigrant labor (both foreigners and Brazilians), which had a direct impact in the epidemiological situation.Irrespectively, we believe the percentage if internments in São Paulo, which in 1942 was so much higher than in the rest of the country, was due more to the prophylactic policy adopted in the state than the endemic proportions of the disease.

Conclusion
The isolationist model adopted in São Paulo at the start of the 1930s was accepted by some countries as the ideal method of combating Hansens disease, given the lack of an appropriate treatment and in view of the expectations to wipe out the disease in a short space of time.
Isolationism was a direct prophylactic policy.It was designed to eliminate the endemic of Hansens disease by removing the focuses of infection the sick and thereby not making indirect prophylactic policy a primary concern.An analysis of the discourse and actions accompanying the São Paulo model reveal the lack of concern for the need to improve housing, nutrition, labor conditions etc., even in infected areas.The plan was to end the endemic nature of the disease by controlling the infected individual, a practice that was also adopted to combat other endemic diseases.
Once sulfone treatment was discovered, the prophylactic policy recommendations made by the international scientific community underwent important modifications.Leprosy congresses began to question the need for isolating patients and to recommend only selective isolation, such was the case in the Madrid Congress in 1953 and the Rome Congress in 1956.In the final resolutions of the 1958 Tokyo Congress, isolation was considered outdated.However, irrespective * These figures include leper colonies, hospitals and sanatoriums (Source: Revista Brasileira de Leprologia, vol.X, June 1942).

State
Nº of scientific progress and international recommendations, the São Paulo Leprosy Prophylaxis Department continued its policy of compulsory isolation for Hansens disease patients.
But the impact of these international congresses in Brazil did occur on a federal level, beginning in the 1950s.The National Leprosy Service subscribed to the view that compulsory isolation was outdated and its staff helped alter federal legislation, passing federal decree n o 68 of 5/ 7/62 that abolished isolation.However, the fact that São Paulos DPL had its own budget and enjoyed relative autonomy from federal funds, enabled it to defy the new national and international rules that countered its working method.The São Paulo DPL ignored the federal decree and maintained its isolationist policy in the state until 1967.
The prophylactic policy of compulsory isolation came to a close in São Paulo after a decree was passed by governor Abreu Sodré. 29The DPL was restructured and stripped of its authority.The restructuring took place on 7/6/1967 and it was later transformed into the Hansens Disease and Sanitary Dermatology Division when the Health Institute was created in 7/16/1969.
It is interesting to observe that during the 1960s, a decade of intense struggles for freedom and human rights, there is no record of any movement opposing this harsh policy in São Paulo among civil society organizations.The abolishment of compulsory isolation in São Paulo was not achieved by any social movement or the efforts of legal or human rights organizations, but instead by the initiative of the state government.
