ABSTRACT
BACKGROUND:
We aimed to assess the role of different setting and activities in acquiring SARS-CoV-2 infection.METHODS:
In this nationwide case-control study, cases were SARS-CoV-2 infected adults recruited between 27 October and 30 November 2020. Controls were individuals from the Ipsos market research database matched to cases by age, sex, region, population density and time period. Participants completed an online questionnaire on recent activity-related exposures.FINDINGS:
Among 3426 cases and 1713 controls, in multivariable analysis, we found an increased risk of infection associated with any additional person living in the household (adjusted-OR 1â¢16; 95%CI 1â¢11-1â¢21); having children attending day-care (aOR 1â¢31; 95%CI 1â¢02-1â¢62), kindergarten (aOR 1â¢27; 95%CI 1â¢09-1â¢45), middle school (aOR 1â¢30; 95%CI 1â¢15-1â¢47), or high school (aOR 1â¢18; 95%CI 1â¢05-1â¢34); with attending professional (aOR 1â¢15; 95%CI 1â¢04-1â¢26) or private gatherings (aOR 1â¢57; 95%CI 1â¢45-1â¢71); and with having frequented bars and restaurants (aOR 1â¢95; 95%CI 1â¢76-2â¢15), or having practiced indoor sports activities (aOR 1â¢36; 95%CI 1â¢15-1â¢62). We found no increase in risk associated with frequenting shops, cultural or religious gatherings, or with transportation, except for carpooling (aOR 1â¢47; 95%CI 1â¢28-1â¢69). Teleworking was associated with decreased risk of infection (aOR 0â¢65; 95%CI 0â¢56-0â¢75).INTERPRETATION:
Places and activities during which infection prevention and control measures may be difficult to fully enforce were those with increased risk of infection. Children attending day-care, kindergarten, middle and high schools, but not primary schools, were potential sources of infection for the household.FUNDING:
