On this topic, I just came from the store outside. Buying groceries once a week at most here, because of the time it takes to process everything. The precautions here are pretty thorough. Everybody I know (friends, family) goes about it about the same way.
We all go out with something covering our faces, even if it is a handkerchief or a bandana. We come back home, take off our shoes and leave them outside the door. The neighbors have been doing the same thing in that regard.
Once we come inside we wash our hands and toss all the clothes into a bucket we have at the entrance and take a shower. The clothes are to be washed at a high temp. Then we go to the kitchen and disinfect absolutely everything that came from outside. The items from the store, the reusable bags we use for groceries, etc. Some items stay next to the door (wallet, keys, etc). If something does not need its packaging, the package goes to the trash. Then we clean every surface we touched since we came in (light switches, door handles, soap dispensers, faucets, etc). Then the kitchen counter, and then we have the robot vacuum cleaner mop the entire floor of the house with bleach, which is the most common disinfectant here.
Now is this too much? Maybe. But I have asthma, so I'd rather exaggerate 'cuz I don't want to fucking die or spend two weeks alone in an isolated ward watching other people die around me. And I certainly don't want my wife to have to go through something like that.
Now, maybe my chances are better, I'm only 32 and (aside from asthma) quite healthy and fit, I rarely get sick. But even in that case, if for some reason I need medical attention I don't want to take up a bed someone else with worse chances could need. One of those people could be my mom or my dad, both of them are definitely not young and have pre-existing conditions.
Something that is quite clear right now is that this is the way we live now and it will be so for the coming months, even after the lockdown is lifted, this crap is here to stay. Which sucks cuz that entire process takes about 2 hours.
