A total of 622 individuals were screened for SARS-CoV-2 from January to September 2020. Chi-square and logistic regression were used to identify the relationship between sociodemographic characteristics and SARS-CoV-2. Of the 622 tested, 14.3% tested positive. The infection rate was the same for both genders (14.3%). Individuals \u226540 years old, from non-urbanized areas, and healthcare professionals had a higher frequency of infection. The risk of infection was very high in individuals \u226560 years old (AOR: 23.3, 95% CI: 4.83\u2013112), in women (AOR: 1.24, 95% CI: 0.76\u20132.04), in Luanda (AOR: 7.40, 95% CI: 1.64\u201333.4), and healthcare professionals (AOR: 1.27, 95% CI: 0.60\u20132.71), whereas a low risk was observed in individuals from urbanized areas (AOR: 0.44, 95% CI: 0.26\u20130.75). Our results suggest that Angolan authorities should implement a greater effort in non-urbanized areas and among healthcare professionals since when these individuals presented any indication for a COVID-19 test, such as fever\/cough\/myalgia, they were more likely to test positive for SARS-CoV-2 than having some other cause for symptoms.<\/jats:p>","DOI":"10.1371\/journal.pone.0249249","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T15:53:31Z","timestamp":1616687611000},"page":"e0249249","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Sociodemographic
