• SARS-CoV-2 infection risk was associated with having frequented bars and restaurants (OR=1.95) or attending private gatherings (aOR=1.57), according to a multivariate analysis of an online survey administered in France to SARS-CoV-2-infected adults (n=3,426). Survey participants were matched to non-infected controls (n=1713) from October to November by age, sex, population density, and time period. Having one additional household member (aOR 1.16), having children attending day-care or school (aOR approximately 1.3), attending professional gatherings (aOR=1.15), or participating in indoor sports (aOR=1.36) were also significantly associated with higher risk of SARS-CoV-2 infection. By contrast, no increase in risk was associated with frequenting shops, cultural/religious gatherings, or transportation (except for carpooling). Teleworking was associated with a significantly lower risk of infection (aOR 0.65).
