Abstract

Objective: To analyze aspects related to positivity for schistosomiasis in an area of low prevalence in Brazil. Methods: Cross-sectional study, carried out in the first half of 2020, where proportion of positivity was analyzed according to the number of Kato-Katz slides, the diagnostic performance of the test and the creation of a positivity estimation factor from the data of the Information from the Schistosomiasis Surveillance and Control Program (SISPCE). Results: 2,088 slides from 348 individuals were analyzed, with proportion of positivity of 11.8%, 26.7% and 31.0% for 1, 4 and 6 slides analyzed, respectively. There was excellent agreement (Kappa = 0.91) between the reading of 4 and 6 slides. An underreporting of 2.1 times was estimated in the SISPCE data. Conclusion: Increasing the number of blades increased the positivity of Kato-Katz, which can contribute to maximize the control of the disease as a public health problem.
