[Symptoms of SARS-CoV-2 infections in children of day care age].

Day care-aged children infected with SARS-CoV‑2 usually have mild or asymptomatic courses. Their symptoms are similar to those of children who tested negative for SARS-CoV‑2 from the same day care centers; thus, the observed COVID-19 symptoms are nonspecific. Combining data from the two modules is useful: findings from a very large database, as provided by the surveillance data, are complemented by findings from day care center outbreaks, where detailed prospective data on infected children can be compared with those of children who tested negative for SARS-CoV‑2.
