Not everyone has a washer/dryer at home, especially in poorer neighborhoods. It’s a question of hygiene, which in turn affects health.
A lot of people live from paycheck to paycheck and can’t afford to be doomsday preppers. I agree that with people crowding in groceries and pharmacies, it kind of defeats the purpose of lockdown, but of course people need food and medicine.
The rest of this is general comment and not in reply to your post, @mgl.
Everyone should be practicing stringent personal hygiene (that goes for any time, as a matter of fact), people who are old and whose immune systems are vulnerable should be isolating themselves. Anyone in contact with an infected person (or infected themselves) should self-quarantine. People living in the same household with an infected person should keep their distance as best they are able. Social distancing in general should be practiced in public as much as possible.
Bringing everything to a halt for an undetermined period of time is a policy fraught with danger. Big businesses will survive. The government always bails them out anyway. Many small business owners will be ruined, and unemployment is going to skyrocket. Which, in turn, creates additional health problems (both mental and physical) in the population, especially among the most vulnerable.
In short, there’s no magic bullet here. Regardless of which decisions states and the federal government make, there will be consequences.
@JJ3 Best to you and yours.
Best to all of you and your families.
