How long can nCoV persist in water

Russia: New research by the VECTOR Institute in Siberia shows that nCoV is not only destroyed by boiling water but also dies in water at room temperature in 1-3 days.

Experts from the Center for Virology and Biotechnology VECTOR in Novosibirsk, Siberia, Russia, discovered a weak point of nCoV is normal water. The team found that about 90% of viral particles died in water at room temperature within 24 hours and 99.9% of virus particles died within 72 hours. In addition, they confirmed that boiling water completely kills the nCoV immediately.

Although viruses do not multiply in chlorinated water and seawater, they can survive for a while, with a life expectancy directly dependent on the water temperature, the researchers said. Dechlorinated water is also highly effective at killing viruses. The results of the study were published on July 30 by Rospotrebnadzor, the Russian Federal Agency for the Protection of Consumer Rights and Human Rights.

On July 29, Rospotrebnadzor’s top doctor, Anna Popova, reported to Russian President Vladimir Putin the results of monitoring coastal water, swimming pools, water parks and drinking water sources. After conducting hundreds of analyzes, Rospotrebnadzor found no major risks associated with pathogens in the water.

As of July 30, Russia recorded a total of 834,000 nCoV infections, of which 630,000 patients have recovered and 13,802 deaths. The actual infection rate is thought to be much higher. Moscow Mayor Sergei Sobyanin estimates that 60% of the city’s residents have been infected with nCoV, meaning that about 2.4 to 7.2 million people have recovered without serious complications.

Virologists at VECTOR have been at the forefront of nCoV research since the outbreak of the pandemic. They participated in developing testing kits to check for viruses and antibodies, and selected more than a dozen vaccines by the end of March 2021. VECTOR was licensed for clinical trial of vaccine in humans from July 27. Located in the scientific city of Koltsovo, VECTOR was established in the 1970s to develop vaccines and biological weapons prevention measures.
