RT Journal Article SR Electronic T1 Inactivation of SARS-CoV-2 in chlorinated swimming pool water JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.04.19.440446 DO 10.1101/2021.04.19.440446 A1 Jonathan C Brown A1 Maya Moshe A1 Alex Blackwell A1 Wendy S Barclay YR 2021 UL http://biorxiv.org/content/early/2021/04/20/2021.04.19.440446.abstract AB SARS-CoV-2 transmission remains a global problem which exerts a significant direct cost to public health. Additionally, other aspects of physical and mental health can be affected by limited access to social and exercise venues as a result of lockdowns in the community or personal reluctance due to safety concerns. Swimming pools have reopened in the UK as of April 12th, but the effect of swimming pool water on inactivation of SARS-CoV-2 has not yet been directly demonstrated. Here we demonstrate that water which adheres to UK swimming pool guidelines is sufficient to reduce SARS-CoV-2 infectious titre by at least 3 orders of magnitude.Competing Interest StatementThe authors have declared no competing interest.
