Abstract Objective: to analyze the factors related to sleep disorders reported by Nursing professionals during the COVID-19 pandemic. Method: this is a cross-sectional and analytical study conducted with Nursing professionals from all Brazilian regions. Sociodemographic data, working conditions and questions about sleep disorders were collected. The Poisson regression model with repeated measures was used to estimate the Relative Risk. Results: 572 answers were analyzed, which revealed that non-ideal sleep duration, poor sleep quality and dreams about the work environment were predominant during the pandemic, with 75.2%, 67.1% and 66.8% respectively; as well as complaints of difficulty sleeping, daytime sleepiness and non-restorative sleep during the pandemic were reported by 523 (91.4%), 440 (76.9%) and 419 (73.2%) of the Nursing professionals, respectively. The relative risk of having such sleep disorders during the pandemic was significant for all variables and categories studied. Conclusion: non-ideal sleep duration, poor sleep quality, dreams about the work environment, complaints regarding difficulty sleeping, daytime sleepiness and non-restorative sleep were the predominant sleep disorders among Nursing professionals during the pandemic. Such findings point to possible consequences on health, as well as on the quality of the work performed.

RESUMO Estudo transversal cujo objetivo foi identificar a prevalência e os fatores associados à violência no trabalho (física e/ou verbal) contra residentes multiprofissionais que atuam em um hospital universitário durante a pandemia da Covid-19. Foi desenvolvido um censo, em julho de 2020, com 67 residentes. Dados foram coletados por meio de questionário eletrônico, avaliando-se a violência física e verbal mediante autorrelato. Associações entre a ocorrência de violência vivida durante a pandemia e as variáveis independentes (sociodemográficas, psicoemocionais e atendimento ao paciente com Covid-19) foram analisadas mediante testes estatísticos e Regressão de Poisson (RP) com variância robusta. A prevalência de violência foi de 22,4%. Diferenças entre grupos foram observadas ao comparar as ocupações e o grau de satisfação com a residência, com maior proporção de fisioterapeutas e assistentes sociais, assim como de residentes insatisfeitos entre os que relataram violência (p≤0,005). Após análise de regressão, a violência esteve associada ao aumento da idade (RP=1,25; IC95% 1,12-1,40) e a níveis de ansiedade moderados/graves (RP =2,87; IC 95% 1,12-1,40). Os achados apontam para a necessidade de implementação de medidas institucionais de prevenção e controle da violência no trabalho, considerando os fatores associados durante a pandemia.

ABSTRACT Cross-sectional study which objective was to identify the prevalence and factors associated with workplace violence (physical and/or verbal) against multiprofessional residents working at a Brazilian university hospital during the COVID-19 pandemic. A census was developed in July 2020 with 67 residents. Data were collected through an electronic questionnaire, evaluating physical and verbal violence through self-report. Associations between the occurrence of violence experienced during the pandemic and independent variables (sociodemographic, psycho-emotional, and patient care with COVID-19) were analyzed using statistical tests and Poisson Regression (PR) with robust variance. Differences between groups were observed when comparing occupations and the degree of satisfaction with the residence, with a higher proportion of physical therapists and social workers, as well as dissatisfied residents among those who reported violence (p≤0.005). After regression analysis, violence was associated with increase in age (PR=1.25; 95%CI 1.12-1.40) and moderate/severe anxiety levels (RP=2.87; 95%CI 1.12-1.40). The findings point to the need to implement institutional measures for the prevention and control of workplace violence considering the factors associated with it during the pandemic.

RESUMO Introdução: A obesidade infantil está aumentando e, como consequência, gera complicações de saúde decorrentes do comportamento sedentário e baixos níveis de aptidão física. Existem poucos estudos que envolvem crianças, perfis metabólicos e cardiorrespiratórios e futebol. Objetivo: O objetivo foi medir os efeitos de um programa de futebol recreativo reduzido de 12 semanas sobre o risco cardiometabólico e respostas individuais em meninos com sobrepeso ou obesos. Métodos: Treze meninos de 8 a 12 anos (34,9 ± 11,6% de gordura corporal) participaram de um programa de treinamento de futebol recreativo reduzido de 12 semanas com duas sessões de 80 minutos por semana em intensidades acima de 80% da frequência cardíaca máxima. As características antropométricas, a aptidão cardiorrespiratória, o perfil metabólico e as respostas individuais do pico de consumo de oxigênio (VO2pico), carga máxima de trabalho (Wmáx), glicemia e insulina em jejum, HOMA-IR, LDL-C, HDL-C, CT e TG foram medidos pré e pós-treinamento. Resultados: considerando as respostas individuais dos participantes, o treinamento recreativo de futebol foi eficaz para melhorar as variações da potência máxima e do tempo até a exaustão, bem como promover pelo menos uma alteração benéfica nos fatores de risco cardiometabólico em 84% das crianças com sobrepeso ou obesidade. Não houve diferenças entre as características antropométricas pré e pós-programa, perfis metabólicos ou VO2pico. Conclusões: Doze semanas de programas de futebol recreativo reduzido foram capazes de melhorar a potência máxima e a capacidade anaeróbica, bem como manter os níveis de fatores de risco cardiometabólicos em meninos com sobrepeso e obesos. Nível de evidência I; Estudo prospectivo de alta qualidade (todos os pacientes foram inscritos no mesmo estágio da doença, com > 80% dos pacientes inscritos) .

ABSTRACT Introduction: Childhood obesity is increasing and, as a consequence, it generates health complications resulting from sedentary behavior and low levels of physical fitness. There are few studies involving children, metabolic and cardiorespiratory profiles, and soccer. Objective: The purpose was to measure the effects of a 12-week recreational small-sided soccer program on cardiometabolic risk and individual responses to cardiometabolic risk factors in overweight or obese boys. Methods: Thirteen boys aged 8-12 years (34.9±11.6% body fat) participated in a 12-week recreational small-sided soccer training program with two 80-minute sessions per week at intensities over 80% of the maximal heart rate. Anthropometric characteristics, cardiorespiratory fitness, metabolic profile, individual responses to peak oxygen uptake (VO2peak), maximal workload (Wmax), fasting blood glucose, insulin, HOMA-IR, LDL-C, HDL-C, TC, and TG were measured both pre- and post-training. Results: Considering the individual responses of the participants, recreational soccer training was effective in improving variations in maximum power and exhaustion time, as well as promoting at least one beneficial change in cardiometabolic risk factors in 84% of the overweight or obese children. There were no differences between pre- and post-program anthropometric characteristics, metabolic profiles, or VO2peak values. Conclusion: Twelve-week recreational small-sided soccer programs were able to improve maximal power and anaerobic capacity and maintain cardiometabolic risk factor levels in overweight and obese boys. Level of evidence I; High-quality prospective study (all patients were enrolled at the same stage of disease, with >80% of patients enrolled) .

ABSTRACT Objective: To identify the presence of musculoskeletal pain during the working day among nursing professionals in material and sterilization centers. Method: A cross-sectional study with 36 nursing professionals who answered a questionnaire for personal characterization and diagnosis of musculoskeletal disorders and Corlett and Manenica's diagram of painful areas at the beginning and end of the working day. Frequency distribution analysis, Fisher's exact test and likelihood ratio were carried out. Results: The presence of pain was reported by 80.6% (n = 29) of the participants at the start of the working day and 94.4% (n = 34) at the end, and the prevalence of musculoskeletal disorders was 66.6% (n = 24). There was a statistically significant difference in the number of segments with pain between professionals with and without a diagnosis of musculoskeletal disorders, in the initial and final assessments. The lumbar spine had a higher prevalence of pain in both assessments. Conclusion: The prevalence of pain increased towards the end of the working day and indicates that there may be a relationship between the work process and the development of pain. It is important to identify working conditions that may contribute to the onset of pain and to adopt preventive measures.

Abstract Rapid Diagnostic Tests (RDT) are useful to identify syphilis cases, particularly for hard-to-reach populations and if laboratory services are scarce. However, RDT performance may be suboptimal. We aimed to assess the sensitivity and specificity of a syphilis RDT using well-characterized blood donors’ samples. We categorized samples from 811 blood donors into five groups: 1 - Samples with reactive Chemiluminescence (QML), FTA-Abs, and VDRL; 2 - Samples with reactive QML and FTA-Abs, and nonreactive VDRL; 3 - Samples with reactive QML, and nonreactive for other markers (false-positives); 4 - Controls with nonreactive QML; and 5 - Samples reactive for HIV, with nonreactive QML. Sensitivity was tested in groups 1 (overall and according to VDRL titers) and 2; specificity was tested in groups 3‒5. The RDT had high specificity, even in samples reactive for HIV. The sensitivity was high (91.9%) in samples with reactive VDRL but varied between 75.0%‒100% according to VDRL titers. The overall sensitivity was lower (81.3%) in samples with reactive FTA-Abs and nonreactive VDRL. The RDT is a useful tool to detect active syphilis but may be more limited for cases with very early or remote infection, or those with prior treatment. When higher sensitivity is needed, additional strategies including recurrent testing or laboratory-based tests may be required.

ABSTRACT The objective of the present study was to evaluate the qPCR for detection and enumeration of Staphylococcus aureus and Streptococcus agalactiae using different milk samplings in comparison to the conventional microbiology. Four dairy herds with a history of subclinical mastitis caused by S. aureus and S. agalactiae were selected. Sampling approach included milk samples from bulk tank (BT), cow level (composite samples, CO), and mammary quarter level (MQ) from 785 lactating cows. Three consecutive monthly milk samplings were carried out, totaling 3347 MQ milk samples, 912 CO, and 12 from BT. All collected milk samples were subjected to conventional microbiology and qPCR for detection and enumeration of S. aureus and S. agalactiae. The qPCR showed 71.5% of diagnostic sensitivity for S. aureus isolated from MQ milk samples, 71.8% for CO, and 50% for BT milk samples compared with conventional microbiology methodology. Taken together, the diagnostic sensitivity for S. agalactiae isolated from MQ milk samples was 90.2, 87.7 for CO, and 90.9% for BT milk samples. In general, the qPCR methodology enabled the detection of S. aureus and S. agalactiae, regardless of the type of milk sampling. The direct use of milk samples to estimate the counting of S. aureus by qPCR demonstrated lower sensitivity than the counting of S. agalactiae, which can be explained by the pathogen infection dynamics and differences in milk sample type.

ABSTRACT: Laminitis is a disease that affects the dermis and epidermis of the bovine hoof, generating changes in the hoof capsule. This study evaluated the effects of clinical laminitis diagnosed after the adaptation phase to confinement on the morphology, density, and mineral composition of the hoof of Nellore cattle after finishing. The animals were separated in the first weeks of confinement into a sick group (SG), with clinical laminitis, and a healthy group (HG). SG animals had higher heel length, dorsal wall length, toe height, and diagonal hoof length (p<0.05) than healthy animals. The dermal laminae had similar measurements for thickness, length, and spacing between them between SG and HG. Animals with laminitis showed congestion, hemorrhage, and basement membrane irregularities on histology. Computed microtomography (μCT) revealed that the hoof density of sick animals is lower than healthy ones. According to the mineral composition by energy-dispersive X-ray fluorescence (ED-XRF) spectrometry, the hooves of animals with laminitis (SG) and healthy ones (HG) were not biochemically different. Therefore, the occurrence of clinical laminitis in Nellore cattle in the first weeks of confinement causes an increase in the morphometric parameters of the hoof capsule and a reduction in the density of the abaxial hoof wall evaluated after the finishing period. This disease does not promote changes in the histomorphometric parameters of the dermal laminae and the percentage of minerals in the abaxial hoof wall.

RESUMO: A laminite é uma doença que afeta a derme e epiderme do casco de bovinos gerando alterações no estojo córneo. O estudo avaliou os efeitos da laminite clínica diagnosticada após a fase de adaptação ao confinamento na morfologia, densidade e composição mineral do casco de bovinos da raça Nelore após terminação. Nas primeiras semanas de confinamento, os animais foram separados em um grupo doente (GD) com laminite clínica e em um grupo saudável (GS). Os animais do GD apresentaram maior comprimento de talão, comprimento da parede dorsal, altura da pinça e comprimento diagonal do casco (p<0,05) do que os saudáveis. As lâminas dérmicas tiveram medidas semelhantes para espessura, comprimento e espaçamento entre elas entre GD e GS. Animais doentes apresentaram congestão, hemorragia e irregularidades da membrana basal na histologia. A microtomografia computadorizada (μCT) revelou que a densidade do casco de animais doentes é menor do que o saudável. Para a composição mineral por meio da espectrometria de fluorescência de raio-X por dispersão de energia (ED-XRF), o casco dos animais doentes (GD) e dos saudáveis (GS), não se mostraram diferentes bioquimicamente. Conclui-se que a ocorrência de laminite clínica em bovinos da raça Nelore nas primeiras semanas de confinamento ocasiona aumento de parâmetros morfométricos do estojo córneo e redução da densidade da parede abaxial do casco, avaliados após o período de terminação. Essa enfermidade não promove modificações nos parâmetros histomorfométricos das lâminas dérmicas e na porcentagem de minerais da parede abaxial do casco.

ABSTRACT: The determination of eugenol in clove essential oil was performed using a smartphone-operated device, which was used for image capture and processing. The colorimetric reaction with the Folin-Ciocalteu reagent was used, and the lighting conditions were evaluated to capture images directly in 2 mL disposable vessels. The free application PhotoMetrix UVC was used for partial least squares regression calibration with suitable values (R² greater than 0.99). The accuracy of the proposed method was compared with traditional methods, such as gas chromatography (GC) and spectrophotometry, and it can be observed that there were no significant differences (Student’s t-test (P > 0.05), with agreements from 97% to 101%. The smartphone method allowed the evaluation of several samples in a few minutes, with simple analysis steps and easy interpretation of the results. The miniaturized scale allowed the use of small amounts of reagents with minimal waste generation. Therefore, the proposed method can be easily operated in the field and allows the evaluation of the quality of clove essential oil in places of restricted access without the need for a laboratory structure and specialized analysts.

Abstract The genus Candida represents the main cause of infections of fungal origin. Some species stand out as disease promoters in humans, such as C. albicans, C. glabrata, C. parapsilosis, and C. tropicalis. This study evaluated the antifungal effects of propyl (E)-3-(furan-2-yl) acrylate. The minimum inhibitory concentration of the synthetic compound, amphotericin B and fluconazole alone against four species of Candida ranged from 64 to 512 μg/mL, 1 to 2 μg/mL, and 32 to 256 μg/mL, respectively. The synergistic effect of the test substance was observed when associated with fluconazole against C. glabrata, there was no antagonism between the substances against any of the tested strains. The potential drug promoted morphological changes in C. albicans, decreasing the amount of resistance, virulence, and reproduction structures, such as the formation of pseudohyphae, blastoconidia, and chlamydospores, ensuring the antifungal potential of this substance. It was also possible to identify the fungicidal profile of the test substance through the study of the growth kinetics of C. albicans. Finally, it was observed that the test compound inhibited the ergosterol biosynthesis by yeast.

Abstract: Aim Evaluate the structure of the aquatic macrophytes assembly of the Jacarecica II Dam, Areia Branca, Sergipe, and verify if distance from the margin is a driver for species richness, and composition in this environment. Methods We settled transects where we plotted quadrats and subplots. The transects were perpendicular in relation to the reservoir margin, and the first quadrat was placed on the margin with the four following ones completely over the water surface. We estimated cover area for each macrophyte species in each quadrat. Each species was also classified according to its life form. We calculated community indexes and tested the influence of the distance from the margin on the structure of macrophyte assemblies. Results We sampled 10 emergent and four free-floating species, resulting in a richness of 14 species. The species with higher importance value were weedy and ruderal species (Salvinia auriculata and Eichhornia crassipes). The distance to the margin caused changes in macrophyte assembly and presented negative relation with species richness. Conclusions The studied assembly presents few species, with some presenting great dominance. This dominance reflects the anthropization of these habitats. Besides, the species composition and richness are modified in the sense that emergent and free-floating species co-occur in marginal quadrats, but only free-floating species occur in quadrats that are in areas that are more distant from the reservoir margin.

Resumo: Objetivo Avaliar a estrutura das assembleias de macrófitas aquáticas do reservatório Jacarecica II (Areia Branca, Sergipe) e verificar se a distância da margem é um fator estruturante da riqueza e composição de macrófitas nesse ambiente. Métodos Nós instalamos transectos em que foram plotadas parcelas. Os transectos foram plotados perpendiculares em relação à margem e a primeira parcela foi alocada na margem e as outras quatro colocadas em áreas cobertas por água. Nós estimamos a área de cobertura de cada espécie de macrófita por parcela e cada espécie foi classificada de acordo com sua forma de vida. Nós calculamos índices fitossociológicos e testamos a influência da distância da margem na estrutura das assembleias de macrófitas. Resultados Nós amostramos 10 espécies emergentes e quatro espécies flutuantes-livres de macrófitas aquáticas. As espécies com maiores valores de importância foram as espécies ruderais e invasoras (Salvinia auriculata e Eichhornia crassipes). A distância da margem alterou a assembleia de macrófitas e apresentou efeito negativo na riqueza de espécies. Conclusões A assembleia estudada apresentou poucas espécies, sendo algumas muito dominantes. Essa dominância reflete a antropização desses habitats. Além disso, a composição e diversidade das espécies são modificadas no sentido de que as espécies emergentes e flutuantes livres co-ocorrem nas parcelas das margens, mas apenas as flutuantes livres ocorrem em parcelas mais distantes da margem.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract Background: Diseases of the circulatory system are the leading cause of illness and death in the world population. Objective: Estimate the prevalence of high risk for coronary events (HRC) and associated factors in the Brazilian adult population. Method: This is a cross-sectional study, based on data from the National Health Survey 2013. The association of this condition with sociodemographic, health condition, and habits and lifestyle was evaluated for individuals as in HRC, according to the first stratification phase of the I Brazilian Directive of Cardiovascular Prevention. Statistical analysis was performed in three stages: descriptive; bivariate; and multiple analysis. Sampling weights and design effect of the complex sampling plan were considered, using the survey library of the statistical program R, version 3.2.2. Results: The prevalence of HRC in the Brazilian population was 11.06% (95%CI 10.83–11.29). A higher prevalence of HRC was observed with advancing age, in individuals living in the Central-South, who self-rated their health as poor/very poor, former smokers, and individuals with systemic arterial hypertension. Conclusions: The Brazilian population presented a high prevalence of HRC and, thus, has a more than 20% risk of an acute coronary event in the next ten years, if prevention and control measures are not taken.

Resumo Introdução: As doenças do aparelho circulatório representam a principal causa de adoecimento e mortes na população mundial. Objetivo: Estimar a prevalência de alto risco para evento coronário (ARC) e os fatores associados na população adulta brasileira. Método: Estudo transversal, com base nos dados da Pesquisa Nacional de Saúde 2013. Para os indivíduos classificados em ARC, segundo a primeira fase de estratificação da I Diretriz Brasileira de Prevenção Cardiovascular, avaliou-se a associação dessa condição com variáveis sociodemográficas, condição de saúde e hábitos e estilo de vida. A análise estatística foi realizada em três etapas: descritiva, bivariada e múltipla. Consideraram-se os pesos amostrais e o efeito de desenho do plano de amostragem complexo, utilizando-se da biblioteca survey do programa estatístico R, versão 3.2.2. Resultados: A prevalência de ARC na população brasileira foi de 11,06% (IC95% 10,83–11,29). Observou-se maior proporção de ARC com o avançar da idade, em indivíduos residentes no centro-sul, que autoavaliaram a saúde como ruim/muito ruim, ex-fumantes e hipertensos. Conclusões: A população brasileira apresentou alta prevalência de ARC e, assim, possui mais de 20% de risco de um evento coronário agudo nos próximos dez anos, caso medidas de prevenção e controle não sejam tomadas.

ABSTRACT Background: Brazil Nuts (BN) tree is a species of high importance in Amazon region. Their continuous use by traditional communities is often related to disturbances that lead to larger degraded areas where this species is commonly found (“BN groves”). Here we aimed to explore the ecological patterns of BN groves vegetation and its relationship with BN trees and evaluate their potential as a source of carbon credits. We sampled 15 circular plots, with Brazilian Nut trees as the center (focal trees) and collected morphometric data from the focal trees. Additionally, we evaluated fruit production for a period of 5 years to obtain annual measurements, which were used as a proxy of the anthropic impact associated with the collection process. Through analysis of the data, we: i) examined the effects of BN trees on the adjacent vegetation; ii) quantified the potential amount of carbon credits in the adjacent vegetation and in the focal trees by converting carbon stock to equivalent CO2. Results: The adjacent vegetation structure was influenced by the size of BN trees (focal trees). No important effects of BN trees on the adjacent vegetation floristic composition and functional attributes were found. Additionally, we found that Brazilian Nut groves possess a significant potential for carbon credits that could be leveraged in the future carbon credit market, Conclusion: The study highlights the potential for carbon credit generation in Brazil nut groves in the Southeast Amazon as a means of supporting conservation and restoration efforts in these environments.

RESUMO A epidemiologia baseada em esgotos é uma importante ferramenta de saúde pública com grande aplicabilidade no enfrentamento à pandemia de COVID-19, visto que indivíduos infectados são capazes de excretar partículas de SARS-CoV-2. Diante desse contexto, este estudo objetivou correlacionar o número de casos de COVID-19 com variáveis físicas e químicas e presença do vírus em amostras de esgoto bruto provenientes de uma estação de tratamento de esgoto (ETE) do município de Lavras (MG) coletadas entre as 19ª e 25ª semanas epidemiológicas. As amostras foram concentradas pelo método de adsorção em membrana eletronegativa, e o RNA de SARS-CoV-2 foi extraído, detectado e quantificado por reação da transcriptase reversa seguida pela reação em cadeia da polimerase (RT-qPCR) utilizando-se oligonucleotídeos e sondas para o gene N. Ademais, as variáveis pH, sólidos suspensos totais e demanda química de oxigênio foram avaliadas. Os casos de COVID-19 foram obtidos de boletins epidemiológicos disponibilizados pela prefeitura. Na 24ª semana epidemiológica, observou-se redução na concentração viral (cópias L-1) concomitantemente às medidas de enfrentamento à pandemia iniciadas pelo município. Correlação positiva forte e significativa (p < 0,05) entre carga viral e número de casos confirmados foi obtida por meio do teste de Spearman, entretanto não houve correlação entre a presença do vírus e as características físicas e químicas do esgoto. Sugere-se, portanto, que novas pesquisas sejam realizadas com a finalidade de rastrear a concentração de SARS-CoV-2 em águas residuárias, corroborando, desse modo, com o enfrentamento à pandemia e a obtenção de sistemas de vigilância epidemiológica por meio do monitoramento de esgotos.

ABSTRACT Wastewater-based epidemiology is an important public health tool with great applicability when facing the COVID-19 pandemic, since infected individuals are able to excrete SARS-CoV-2 particles. In this context, this study aimed to correlate the number of cases of COVID-19 with physical and chemical variables and the presence of the virus in raw sewage samples from a sewage treatment plant (STP) in the municipality of Lavras, Minas Gerais, Brazil, collected between the 19th and 25th epidemiological weeks. The samples were concentrated by electronegative membrane adsorption method and SARS-CoV-2 RNA was extracted, detected, and quantified by RT-qPCR using oligonucleotides and probes for the N gene. Moreover, the variables pH, total suspended solids, and chemical oxygen demand were evaluated. COVID-19 cases were obtained from epidemiological bulletins made available by the municipal government. From the 24th epidemiological week on, a reduction in viral concentration (copies L-1) was observed concomitantly with the pandemic response countermeasures initiated by the municipality. A strong and significant positive correlation (p<0.05) between viral load and number of confirmed cases was obtained through Spearman’s test. However, there was no correlation between the presence of the virus and the physical and chemical characteristics of the sewage. Therefore, it is suggested that further research be carried out in order to track SARS-CoV-2 concentrations in wastewater, thus corroborating with the fight against the pandemic and the achievement of epidemiological surveillance systems based on sewage monitoring.
