Update: COVID Virus can survive up to 7 days on a mask. New data from The Lancet on virus stability at different temperatures, on different surfaces, and vs different disinfectants

A new study in The Lancet Microbe provides new data on the stability of SARS-CoV-2.

The authors write:

Overall, SARS-CoV-2 can be highly stable in a favourable environment,4 but it is also susceptible to standard disinfection methods.

There was an important finding in this study relevant for people using masks

But overall the results are well summarized here

Here’s some data from the paper (my annotations in blue) on stability with temperature. Note they are testing for infectious virus and not just viral RNA

On various surfaces

And with various disinfectants and pH
