New rule is gonna be 48 hour quarantine for any packages.
Mist it with rubbing alcohol and stick it in a sunny corner for a few days.
I just wipe them down with disinfecting wipes, then wash my hands after disposing the box.
I think at some point we need to not make this an environmental disaster from over consumption of disposable items.
It's really starting to get a bit out of hand.
What's concerning to me as a definite non-scientist is that cardboard is the only one of these materials that is porous and "rippable", would it be theoretically possible for the virus to go airborne if you rip up contaminated cardboard?
In addition, it was a lab experiment and from what I read, neither is it known how big the droplets were they tested with nor does anybody know how many virus particles are present in real droplets and how many might be transfered by smiring. Drying of droplets might happen faster or slower in practice, based on the environmental conditions.
And before quarantining your next package for days, just remember: Washing your hands will get rid of the virus, it doesn't travel through the skin - you would have to rub it in eyes, nose or mouth.
Given the lack of specific data, two week quarantine is the practice we're using at home. Unboxing things isn't as important as mitigating the threat of insufficiently-characterized, novel pathogens that our immune systems have basically no experience with.
