Abstract
Active case finding in the population is a critical strategy in epidemic scenarios to mitigate disease spread. During the COVID-19 pandemic, social isolation of confirmed cases was identified as a key preventive measure to reduce new infections, with mass testing serving as an essential tool for its implementation. This study proposes using the positive predictive value of the epidemiological surveillance system as a guide to direct active case finding in epidemic scenarios that require social isolation to contain disease spread. Estimating and applying the positive predictive value could become a valuable resource for public health decision-makers in pandemic contexts similar to COVID-19. Its implementation would facilitate resource prioritization and optimize containment measures, contributing to a more effective response to epidemic outbreaks.
