How Do People Catch Covid-19?

Coronavirus lingering on chilled salmon may be infectious for more than a week, according to researchers in China, where imported fish have been investigated as a potential source of infections.

Researchers at the South China Agricultural University and Guangdong Academy of Agricultural Sciences in Guangzhou found SARS-CoV-2, the virus that causes Covid-19, collected from salmon samples could survive for eight days at 4 degrees Celsius (39 degrees Fahrenheit). That’s roughly the temperature at which the fish are transported. The research was released Sunday in a report ahead of publication and peer review.
