Summary:Introduction: SARS-CoV-2 affects the epithelial cells of the respiratory tract, causing severe infections. Since it is a pathology with a high level of transmissibility, it becomes central to mass testing. In addition, there was also a need to monitor the epidemic through serological tests. Objective: Evaluate the presence of antibodies against SARS-CoV-2 in the community residing in Beira Baixa through immunological screening tests. Materials and methods: Analytical, cross-sectional, and observational study, whose sample consists of 206 individuals. Data collection took place between February and April 2021, in the laboratories of the Dr. Lopes Dias Higher School of Health. Verbal informed consent, a questionnaire to collect sociodemographic data and the serological test were applied. Results: Of the total number of participants, 15.5% admitted to having had COVID-19, of which 0.5% suspected they had been infected and 84% said they had never been infected. Regarding the presence of antibodies, 2.9% of the tests performed were positive for the presence of IgM's while 30.1% were positive for the presence of IgG's. Regarding vaccination, at the time of the investigation only 10.2% of the participants were vaccinated, of which 9.7% had IgG antibodies. Conclusion: Rapid serological tests can provide information about the presence of antibodies to SARS-CoV-2, thus being a very advantageous tool for immunity studies.   DOI: 10.56238/isevjhv1n2-001 Introdução: O SARS-CoV-2 afeta as células epiteliais do trato respiratório, causando infecções graves. Por ser uma patologia com um alto nível de transmissibilidade, torna-se central para os testes em massa. Além disso, houve também a necessidade de monitorar a epidemia através de testes serológicos. Objetivo: Avaliar a presença de anticorpos contra a SRA-CoV-2 na comunidade residente na Beira Baixa através de testes imunológicos de triagem. Materiais e métodos: Estudo analítico, transversal e observacional, cuja amostra consiste de 206 indivíduos. A coleta de dados foi realizada entre fevereiro e abril de 2021, nos laboratórios da Escola Superior de Saúde Dr. Lopes Dias. Foi aplicado o consentimento informado verbal, um questionário para coleta de dados sociodemográficos e o teste serológico. Resultados: Do número total de participantes, 15,5% admitiram ter tido COVID-19, dos quais 0,5% suspeitaram ter sido infectados e 84% disseram nunca ter sido infectados. Com relação à presença de anticorpos, 2,9% dos testes realizados foram positivos para a presença de IgM's, enquanto 30,1% foram positivos para a presença de IgG's. Quanto à vacinação, no momento da investigação, apenas 10,2% dos participantes foram vacinados, dos quais 9,7% tinham anticorpos IgG. Conclusão: Os testes sorológicos rápidos podem fornecer informações sobre a presença de anticorpos ao SRA-CoV-2, sendo assim uma ferramenta muito vantajosa para estudos de imunidade.   DOI: 10.56238/isevjhv1n2-001
