Supply shipments from Amz are a PITA to disinfect because they are often wrapped in a nested, Russian doll fashion --bag within a bag within a box, etc.  Each layer has the possibility of exposure.

Given that the packaging usually happens a few days before arriving at the doorstep, wouldn't a 48 hour quarantine of packages be enough in most cases to minimize the risk?

I posted a study yesterday that said 72 hrs viability on paper surfaces, IIRC.

I read an article with an infectious disease specialist who went over that paper and noted that while the virus was still alive on *hard* surfaces (dies quicker on absorbent surfaces) after 72 hours, it was only 0.1% of the original sample that was still alive. So yes it is still detectable in lab conditions (21C to 23C degrees IIR), but 99.9% of the original sample was dead (or whatever the proper term for a virus is).
