I thought 8 months ago experts agreed that paper masks were useless for the general public.
30? years ago herd immunity was an agreed approach for measles. 10 months ago it was the general approach to the common cold in kindergardens.
EDIT: I personally think that pebbles in the shoes would be more effective than masks because it would make people stay at home even more.
Herd immunity, to my knowledge, has never developed for the common cold, because there are several hundred viruses responsible and they're rather changeable. The general approach, as I recall it, was, "we can't do anything about it, but it doesn't kill too many people, and those at risk can get flu and pneumonia vaccinations."
And herd immunity for measles is due to vaccination. If measles were a novel disease, you would be seeing lockdowns that make San Quentin look open and free.
How about social distancing, mask wearing, basic hygiene, widespread testing/tracing, keeping the sick away from the healthy, limited restrictions in areas with outbreaks/clusters, etc.?
You know, the stuff that the public health experts have been recommending throughout?
I'm not sure that there's really much argument to be had that such measures (given that they've been pretty much standard procedure for disease outbreaks for decades) are appropriate and effective.
