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
This paper also shows that the SARS-CoV-2 can be stable on the inner and outer layer of masks up to 7 days. If it is not used appropriately and/or for long periods or binned inappropriately it could be a serious source of infection. https://t.co/MGUkZ1UeWG— Dr Muge Cevik (@mugecevik) April 4, 2020
But overall the results are well summarized here
More on stability of virus causing #COVIDー19. Key points:— Dr Zoë Hyde (@DrZoeHyde) April 3, 2020
<3 hrs paper, <4 d glass, <7 d steel & plastic;
Found on surgical mask on day 7;
Stable across pH 3-10;
Inactivated by heat (5 mins at 70C), bleach, ethanol, povidone‐iodine, benzalkonium chloride.https://t.co/oQoisymmjt
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
