One of the defenses against frum people who flout the rules of "social distancing" is to point out how many non-frum people and non-Jews also don't follow the guidelines.
That is like saying that we don't have to say Krias Shema twice a day because non-frum people and Goyim don't...
To guard one's health is a religious obligation. Who CARES what everyone else is doing?!!
What we need is a sefer ala the "Mishna Berurah" in Rashi script written by a Rav in conjuction with doctors, codifying healthful behavior and outlawing the opposite. Maybe if people see it in such a format it will convince them. [Such a booklet was written years back by a close talmid of Rav Shach but it doesn't get enough attention].
