To determine if SARS-CoV-2 RNA was present in sewage during the emergence of COVID-19 in the Netherlands, sewage samples of six cities and the airport were tested using four qRT-PCR assays, three targeting the nucleocapsid gene (N1-3) and one the envelope gene (E). Presence of SARS-Coronavirus-2 RNA in sewage and correlation with reported COVID-19 prevalence in the early stage of the epidemic in the Netherlands.
