Coronavirus can survive on surfaces for hours, say scientists

Live Mint  

The novel coronavirus can survive on surfaces or in the air for several hours, according to a US-government funded study. The study was first posted on a medical pre-print website last week before it was peer-reviewed, and attracted much attention, including some criticism from scientists who said that it may have overstated the airborne threat. The team behind the NEJM study performed similar tests on the SARS virus, finding the two viruses behave similarly. But their similar viability fails to explain why the novel coronavirus pandemic has infected close to 200,000 people and caused almost 8,000 deaths, while the SARS epidemic infected about 8,000 and killed nearly 800. "This indicates that differences in the epidemiologic characteristics of these viruses probably arise from other factors, including high viral loads in the upper respiratory tract and the potential for persons infected with SARS-CoV-2 to shed and transmit the virus while asymptomatic," wrote the researchers.
