SARS-CoV-2 Transmission in Belgian Primary Schools of the Federation Wallonia - Brussels: An Epidemiological Pilot Study

The investigators hypothesize that children are less likely to become infected in the school environment, compared to the household or outside the school setting. Primary schools do not play a major role in SARS-CoV-2 spreading. They hypothesize that incidence level in schools is mainly a consequence of community transmission. The incidence level in household and that the secondary attack rate in schools remains at least 5 times lower that the transmission level in households.
