While the risk to children may be minimal, it certainly is not to 40 and 50 year old teachers, the people who are mounting the greatest opposition to reopening of classrooms.
The child might be asymptomatic, but still shedding clouds of the Wuhan virus, and this continued inhalation of the virus is what those older teachers fear almost to the point of phobia.
The teachers can wear masks if they like, even full PPE if that makes them less uncomfortable. But this looks more and more like a strike issue.
The teachers and staff can take anti-malaria medicine (which they would do if they were teaching in Africa or India).
The students may even be immune due to previous innoculations for some other diseases (such as the Measles-rubella-mumps shot).
And that’s EXACTLY the point that many people seem to still be missing (perhaps not unintentionally)..
Children still get the virus. While they don’t DIE from the virus in as large a number as those over, say age 50, they certainly spread it all over creation. And that spread will infect their teachers, parents, bus drivers and others in their schools, homes and communities who are not as safe from serious illness and/or death.
And that’s the problem that keeps getting swept under the rug by the “just open the damned schools NOW” crowd. The US has the most cases in the world at > 5.4 million. THAT’S A PROBLEM, because you can’t expect to just lock anyone 40-50 and over in their houses for the rest of time while the young “let it rip” through society to the point we have tens or even hundreds of millions of infections.
It’s increasingly clear that there are many (probably including Trump who’s now looking to Dr. Atlas that advocates this very approach) that prefer to just let the virus run it’s course and rampage through society unchecked, in a misguided attempt to build up “herd immunity”. That’d be a total disaster, and if we think there are economic problems NOW, just wait to see what will happen when there aren’t only 5.4M infections but tens of millions of cases.
This study rejects your supposition that asymptomatic children spread the virus.
Do they get paid while they strike? Not from the union fund, I mean... from their employer, usually the city.
