This study aimed to show the results from malaria control in the State of Maranhão, based on the state's control plans and on the historical series of malaria records over the period from 1999 to 2007. The evolution of malaria cases was analyzed by comparing the annual incidences of parasitism (total number of cases notified per 1,000 inhabitants) according to geographical area, regional healthcare units and the 46 municipalities included in the plans. Analysis of the results allowed the conclusion that the plans were effective, since the annual incidence went down from 10.1 cases to 1.1 cases per 1,000 inhabitants, i.e. a regression of 89.1%, the largest among all the states in the Amazon region.
