Objetivos Avaliar a prevalência de anticorpos específicos contra o SARS-CoV-2 e analisar a imunidade presumida ao SARS-CoV-2 numa amostra de trabalhadores de uma empresa da região de Aveiro.  Metodologia Trata-se de um estudo observacional, numa população de 400 trabalhadores, estimando uma amostra de 197. A avaliação serológica decorreu entre 14/maio e 28/junho/2020. Aos trabalhadores foi colhida uma amostra de sangue total capilar e realizado o Tell Me Fast Rapid Diagnostic Test Coronavirus (COVID-19) IgG/IgM Antibody Test (S/P/WB).  Resultados Durante o período definido foi realizado teste a 181 trabalhadores e constatou-se que 96,6% dos trabalhadores apresentou IgG/IgM Negativo, 1,7% IgG/IgM Positivo e 1,7% IgG Positivo/IgM Negativo; estimando em 3,4% a prevalência da infeção ao SARS-CoV-2 nos trabalhadores da empresa.  Conclusões Conclui-se uma baixa imunidade de grupo presumida e um potencial risco de infeção por SARS-CoV-2 na comunidade trabalhadora. O Serviço de Saúde Ocupacional deve identificar potenciais riscos de infeção por SARS-CoV-2 nos locais de trabalho, conceber estratégias e implementar medidas adicionais e preventivas, que contribuam para diminuir a taxa de incidência SARS-CoV-2 nos trabalhadores e prevenir um potencial surto na empresa, evidenciando a importância de (in)formar os trabalhadores para aderirem ao plano de contingência COVID-19.]]></p></abstract>

Objectives To evaluate the prevalence of specific antibodies against SARS-CoV-2 and to analyze the presumed immunity to SARS-CoV-2 in a sample of workers from a company in the region of Aveiro.  Methodology This is an observational study, in a population of 400 workers, estimating a sample of 197. The serological evaluation took place between 14/May and 28/June/2020. Workers were taken a capillary whole blood sample and performed the Tell Me Fast Rapid Diagnostic Test Coronavirus (COVID-19) IgG/IgM Antibody Test (S/P/WB).  Results During the defined period, a test was performed on 181 workers, it was found that 96.6% of the workers presented IgG/IgM Negative, 1.7% IgG/IgM Positive and 1.7% IgG Positive/IgM Negative, estimating the prevalence of SARS-CoV-2 infection in company workers at 3.4%.  Conclusions There is a presumed low group immunity and a potential risk of SARS-CoV-2 infection in the working community. The Occupational Health Service must identify potential risks of SARS-CoV-2 infection in the workplace, design strategies and implement additional and preventive measures that contribute to reducing the SARS-CoV-2 incidence rate in workers and preventing a potential outbreak in the company, showing the importance of teaching and training workers to adhere to the COVID-19 contingency plan.]]></p></abstract>
