Related but off-topic question: Does anyone know how long coronavirus is known to last (even rough estimates) on dry/wet surfaces at cold/room temperatures? The practical consideration here is, if I buy something from (say) a supermarket, and (say) someone infected had sneezed on it that day, how long and in what manner would it be helpful for me to leave it outside/in the fridge/etc. to help prevent transmission of the virus? For refrigerated or frozen goods, how much should I expect this duration to be affected?

CDC says they found live virus on Grand Princess surfaces 17 days after passengers left https://www.cnbc.com/2020/03/23/cdc-coronavirus-survived-in-princess-cruise-cabins-up-to-17-days-after-passengers-left.html https://www.cnbc.com/2020/03/23/cdc-coronavirus-survived-in-...

    The CDC report only indicates finding RNA, which is NOT the same as finding a live virus, so that CNBC article is clickbait. >SARS-CoV-2 RNA was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess https://www.cdc.gov/mmwr/volumes/69/wr/mm6912e3.htm?s_cid=mm6912e3_w https://www.cdc.gov/mmwr/volumes/69/wr/mm6912e3.htm?s_cid=mm...

  The CDC report does not state they found live virus after 17 days. See my other comment.

There is a study here of virus stability on dry surfaces: https://www.nejm.org/doi/10.1056/NEJMc2004973 https://www.nejm.org/doi/10.1056/NEJMc2004973

” Furthermore, the stability of this virus is worrisome as well. If you put it in aerosol form and keep it in the air, the half-life is several hours; if you drop it on surfaces of copper or cardboard, it could survive about a day. But if it's on steel or plastic surfaces, you could still detect infectious virus after 72 hours, although the infectivity decreases with time.” Source: Virologist David Ho https://www.caltech.edu/about/news/tip-iceberg-virologist-david-ho-bs-74-speaks-about-covid-19 https://www.caltech.edu/about/news/tip-iceberg-virologist-da...
