No doubt such actions make a tremendous difference.It's already working from what I hear
And in another situation which makes just as much sense:
Even after officials tell people (not in the health care field) not to wear gloves because wearing gloves can make the spread of the virus worse,
I am still seeing police handing out gloves to people in barrios and government officials wearing them when on TV. And I assume some businesses still require gloves to enter their establishments. It appears this is a difficult message to make clear.
