Well I looked at the nature of the virus itself to answer the question about aerosol transmission. I ain't gonna tell you not to be careful, now... When those infection patterns did not materialize, and when the features of the virus were described and understood, I say understood as if we could ever understand these things, I was able to relax about that danger.
The virology explains the epidemiology.
I again am not telling you what to do, I am telling you what I think about this germ. If you can afford to go all Howard Hughes on this, then OK do it, but I cannot and you really don't need to.
People are getting it from direct contact. So when you are opening these packages, keep washing your hands and surfaces and dont rub your nose or your eyes until you wash your hands again.
You can find this virus on the surface...
...of your HANDS! Handwashing is the way. That is THE way. Hand washing works. If we would only...(sigh)
... the nature of the virus itself to answer the question about aerosol transmission...

To all those practicing high-level bio-security:
PERSISTENCE DOES NOT EQUAL CONTAGION.
The virus has a half-life outside the body. Within that time period of persistence, it immediately begins to lose the ability to infect.
Hand washing is good.
Counter cleaning is good.
Cooking food is good.
If you feel better wiping things down, fine.
We are vulnerable seniors who eat a large fresh salad every day. I keep my vegetables wrapped in paper towels, in green bags and dry until immediately prior to use. They last longer. I discard exterior wrapping. Bananas and tomatoes are out on the counter, tomatoes inside their box which is inside a green bag.
We are just fine. I don’t know what they do at the grocery store, but each entire store in my area reeks of alcohol and bleach.
We have two groceries in my town. Both very busy and well-staffed with workers doing 15 hour shifts. THERE ARE NO CASES HERE & (obviously) NO DEATHS.
Transmission is primarily aerosolized liquids from a sneeze or cough. Practice reasonable hygiene, stay 4’ away from people, wipe cart handles and relax.
I am seeing instances of severe anxiety in some people I know or observe. Panic does not equal better protection. Stress lowers immunity.
It is not airborne, BTW. It can travel within human secretions from a sneeze or cough until it lands on something. I have not seen or heard a sneeze or cough when shopping, so far.
