How long can a delta strain of coronavirus live in water

According to Izvestia, specialists of the State Scientific Center of Virology and Biotechnology Vector decided to test the delta variant for survival in water. The study of the samples lasted for three hours, one day, 48 and 72 hours. As a result, it turned out that the delta strain retains its viability for 72 hours. This information coincides with the results that were obtained earlier on other strains.

The study was conducted similarly to the previous ones. There were no differences in the dynamics of inactivation in water in the delta variant," the Vector reported. Previously, scientists conducted an experiment to study the viability of the SARS-CoV-2 virus in drinking and seawater. They observed the dynamics of the residual infectious activity of the virus in samples of drinking dechlorinated water and samples simulating seawater with a concentration of 0.9% and 3.5% sodium chloride salts under normal temperature conditions (24-28 degrees Celsius).

Information was also obtained on the viability of the coronavirus in samples of drinking dechlorinated water stored at a temperature of +4 degrees Celsius for 1, 3, 24, 48 and 72 hours. In samples that mimic seawater of different salinity, stored in laboratory conditions at a temperature of 24-28 degrees, the coronavirus remained viable for 48 hours, regardless of its salinity, and in samples of drinking dechlorinated water — 72 hours, the Vector reported.

To date, there are no confirmed cases of transmission of the SARS-CoV-2 coronavirus through the water of open reservoirs, as well as through drinking water. Due to the limited viability of the virus and its, as a rule, low concentrations in possible bathing areas, the risks of infection through water are minimal," the center explained. According to experts, the threat of COVID-19 infection is associated only with a mass gathering of people on the shore and in the water.
