Presence of SARS-CoV-2 was monitored in nasopharyngeal samples from young children aged 6-30 months attending day-care centres (DCCs) in Belgium from May 2020-February 2022. SARS-CoV-2 carriage among DCC children was only detected from November 2021, after emergence of Delta and Omicron variants, in 9 of the 42 DCCs screened. In only one DCC, two children tested positive for SARS-CoV-2 at the same sampling time point, suggesting limited transmission of SARS-CoV-2 in Belgian DCCs among young children during the studied period.
