INTRODUCTION
Chagas disease can be transmitted by blood transfusion. Herein, we assessed the seropositivity for Chagas disease in blood donors from Alagoas, during 2010-2020.
METHODS
Data were requested from the Alagoas blood center. Time trend analysis was performed using a joinpoint regression model.
RESULTS
Seropositivity rate during the study period was 0.35%, which decreased from 2014 to 2020, (annual percentage change, APC = -29.38;
p-
value <0.05), while the total number of tests performed remained stable (APC = 6.5).
CONCLUSIONS
Despite the drop in the seropositivity for Chagas infection in donors, it is imperative to maintain the screening of donors for the epidemiological control.
