![]() ![]() Cohabitants sharing rooms and talking for 30 min or more were at higher risk among non-cohabitants, the exposure to 1 or more COVID-19 cases, talking for 30 min or more, and the use of ride sharing were associated with a higher risk of infection ( 9). Secondary transmission was shown to occur more frequently among cohabitants than with other contacts, suggesting an increased risk of intrafamilial transmission of SARS-CoV-2 ( 8). The identification of the circumstances and the settings that determine a higher risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission can contribute to inform a more precise implementation of protective measures.Įcological studies identified individuals' socioeconomic status, and population density, overcrowding, and mobility as relevant infection determinants ( 4– 7). These restrictive measures contribute for a reduction in the incidence of COVID-19 cases but severely affect social and economic activities ( 3). Non-pharmaceutical measures range from recommendations to reduce social contacts to nationwide curfews, partial and full lockdowns, and closure of restaurants, bars, and other non-essential services ( 2). Overcrowding, foreign citizenship, low education and working on-site were positively associated with SARS-CoV-2 infection.īefore extended worldwide vaccination coverage is achieved, non-pharmaceutical measures remain an essential option to control COVID-19 pandemic in most countries ( 1). tertiary education: 1.79 1.33–2.42) and no Portuguese citizenship (5.47 3.43–9.22) were important risk factors.Ĭonclusions: The utilization of public transportation, restaurants, and commercial spaces was not associated with increased risk of infection, under capacity restrictions, physical distancing, use of masks, and hygiene measures. ![]() Going to restaurants/other dining spaces (0.73 0.59–0.91), grocery stores (0.44 0.34–0.57) or hair salons (0.51 0.39–0.66), or the use of public transportation did not present a higher risk of infection (0.98 0.75–1.29), under existing mitigation strategies. ![]() Results: Household overcrowding (aOR = 1.47 95% CI 1.14–1.91) and work in senior care (4.99 1.30–33.08) increased while working remotely decreased the risk of infection (0.30 0.22–0.42). We report sex-, age-, education-, and citizenship-adjusted odds ratios (aOR) with 95% confidence intervals (95% CI). Sociodemographic characteristics, individual protective measures, and activities or visited settings were obtained through telephone interview. Methods: We evaluated 1,088 cases, identified through the national surveillance system, and 787 community controls, recruited using random digit dialing. ![]() We thus designed a case-control study to identify relevant settings for community transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Portugal.
