OBJECTIVE:
to analyze Schistosomiasis positivity trends in stool tests in the population in endemic area of the state of Pernambuco, Brazil, 2005-2010.
METHODS:
this was an ecological time series study using secondary data from the Schistosomiasis Control Program Information System, analyzed by Health Region. Trends were evaluated using linear regression and p<0.05 was considered significant.
RESULTS:
Pernambuco had average positivity of 9.2%; the 3rd Region (Palmares) had the highest average positivity (13.8%), followed by the 2nd (Limoeiro: 9.9%) and the 1st (Recife: 7.8%); the 5th Region (Garanhuns) had best average treatment (95.6%), followed by Palmares (86.6%); Pernambuco showed a declining trend of Schistosomiasis positivity (p=0.005).
CONCLUSION:
in general, there has been a declining trend of Schistosomiasis positivity in Pernambuco, despite the reduction in the number of tests; it is important to maintain and intensify control interventions, with priority strategies focused on highest prevalence locations.
