The new coronavirus is most active at temperatures around 4 degrees Celsius and is much weaker at high temperatures, scientists at the University of Hong Kong found.

The virus is very stable at 4 degrees, but is sensitive to heat, according to their report, uploaded to the medical research portal At 4 degrees, the infection lasts more than two weeks, while at 70 degrees, it dies within five minutes.

According to a table presented in the report, at 22 degrees the coronavirus stays active at least for a week, at 37 degrees, for no more than two days, and at 56 degrees, less than 30 minutes.
