In contrast, we assumed fixed effects for all other covariates (meaning an estimated mean effect for the 16 favelas). To account for the spatial clustering of participants in each of the 16 favelas, we assumed a random intercept, meaning that each of the 16 favelas had its unique intercept. Were used to assess factors associated with reactive anti-S IgG serology. Bolsa Familia is a nationwide conditional cash transfer program for families in extreme poverty conditions.

Finally, participants were asked if any household member was a beneficiary of the Bolsa Familia or Auxilío Financeiro Emergencial cash transfer programs. Participants were then asked how frequently any household member including themselves left the house and how often they received visits from people not living at their home over the past two weeks.

The presence of chronic comorbidities (i.e., arterial hypertension, diabetes, cancer, asthma) was assessed with the question “has a health professional ever said you have:”. Participants were questioned about the main means of transportation used during the COVID-19 pandemic (responses categorized as “walk or bike”, “drive own car or motorcycle”, “cab/ridesharing apps/ mototaxi”, or “public transport ”). We also inquired about COVID-19 symptoms and level of adherence to social distancing measures and face mask use in the two weeks prior to the interview adherence responses were categorized as poor, moderate, and intense. Implications of all the available evidence A secondary analysis shows that seroprevalence estimates of anti-N IgG antibodies were lower than of anti-S IgG antibodies. Our analyses showed that young adults, males, and those reporting a large household size and use of public transportation had the highest probability of having a reactive serology. We found COVID-19 seroprevalence (anti-S IgG antibodies) estimates were much higher than anticipated, and spatially varied largely across different favelas. We conducted a population-based study in one of the poorest areas in Rio de Janeiro, Complexo de Manguinhos, which comprises 16 different favelas. Favelas represent a combination of concentrated poverty, insecure and inadequate housing conditions, and lack of access to essential services, such as clean water, sanitation, and healthcare. Added value of this studyīrazil has become a hotspot for COVID-19 globally and the magnitude of the COVID-19 epidemic in Brazil can be, at least partially, explained by the country's massive socioeconomic inequality. Other national or regional population-based studies have limited representativity of individuals living in favelas or slums. Most studies included small samples that were not representative of the entire community/area. Few studies described the seroprevalence of SARS-CoV-2 in urban slums and favelas, using different sampling and recruitment strategies, various serological assays, and periods of the COVID-19 pandemic.

We reviewed the evidence for the seroprevalence of SARS-CoV-2 in Brazil available as of Mar 17, 2022, by searching the Medline and the Virtual Health Library ( Biblioteca Virtual em Saúde of the Pan American Health Organization) databases for articles and preprints, published in English or Portuguese, using the terms AND AND.
