> Going to the grocery store once vs four times is not going to make the difference between you getting the virus or not

Not sure if I'd agree with this. In my neighborhood, there are already multiple confirmed cases (some a few blocks away).

The only way to minimize my (and therefore my family's) exposure to the virus is to avoid any external contact. Encountering 10 people for one grocery trip versus 40 people over 4 separate trips. Statistically, I'd take the one-trip option.
