Introduction: Estimates of the number of individuals infected by severe acute respiratory syndrome coronavirus 2 are important for
health planning and establishment of expectations regarding herd immunity. Methods: Seven testing rounds of a serological survey
were conducted at 1-week intervals between April 19 and May 31, 2020 in Teresina municipality. Results: Over the 7 weeks, serological
positivity increased from 0.56% (95% confidence interval [CI]: 0.18%–1.30%) to 8.33% (95% CI: 6.61%–10.33%), representing 33–53
persons infected for each reported case. Conclusions: Serological screening may be an important tool for understanding the immunity
of a population and planning community interventions.
