Resumo
Objective: To describe study protocol and initial results of research project COVID-Inconfidentes. Method: This
paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in
the population. A household survey was conducted between October and December 2020, in two historic cities
of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-
face interview consisted of administration of a questionnaire containing registration data, sociodemographic
and economic variables, living habits, general health condition, mental health, sleep habits, and eating and
nutrition. Results: We evaluated 1,762 residents, of which 764 (43.4 %) were in Mariana and 998 (56.6 %) in Ouro
Preto. For both cities, 51.9 % of the interviewees were female, with a predominance of the age range 35 to 59
years old (47.2 %). The prevalence of the SARS-CoV-2 infection was 5.5 % in both cities, 6.2 % in Ouro Preto,
and 4.7 % in Mariana (p-value > 0.05). Conclusion: The study was effective to estimate the seroprevalence of
infection by the virus and its findings will enable further analyses of the health conditions of the population
related to social isolation and the risk of infection with SARS-CoV-2.
