Children (n=327) and staff (n=197) attending daycare centers in France during the lockdown from March to May 2020 had similar seroprevalence (4% and 7%, respectively) to a comparator group consisting of laboratory or administrative personnel not occupationally exposed to COVID-19 patients or children (5%). In addition, seropositive children were 7-times as likely to have been exposed to an adult household member with confirmed COVID-19 compared to seronegative children. The authors suggest that during the French lockdown, household transmission seems more likely than transmission within daycare centers. [EDITORIAL NOTE: It is also plausible that the association between child and household contact seroprevalence could be due to transmission from an infected child to a household contact].<\/i><\/p>\n
