Face shields are to protect against body fluid splatter during invasive bodily procedures and while closely treating patients with explosive coughing fits. Even doctors in hospitals treating Covid-19 patients don't wear them outside those types of circumstances. There is no need for the general public to wear them. It's not like fitting your car with a seat belt, it's like fitting it with an ejector seat.

So your argument is that the risk to the average American is low from COVID? Why do we have 300,000 cases then? Why are 1000 people dying a day? That's already 0.1% of the population, and most of them in the past week!

The risk is very high, my wife is a nurse here in the UK and is infected. Fortunately she has light symptoms and a light cough. When I am with her we both wear a face mask, but there is no need for a shield because I’m not intubating her her or at risk of heavy splatter from close range explosive coughing. Again, even doctors in hospitals only wear face shields under specific circumstances, which are situations the general public are not likely to find themselves in. That’s why you don’t even see doctors and nurses wearing face shields in public or taking them home. Outside those specific circumstances they don’t need them, and we don’t need them.

I would humbly suggest that doctors very rarely deal with diseases this dangerous (infectiousness + lethality) and that more extreme protection is warranted. As you well know, it is difficult to not catch this thing.

I would much rather overdo my PPE than underdo it. Overdoing it just costs me a little time, underdoing it costs lives and injury.

If you want to see what it takes to have a hospital where no one gets infected, this is instructive. https://youtu.be/9HsGqQCLzLU

You’re not listening to what he said. He argued no such thing. You however seem content to deprive doctors and nurses of important tools and compromise their safety and patient safety so you can selfishly take something that provides zero protection to you.

Lack of testing and a laggard&lackluster response by authorities. USA will be one of the hardest hit countries in the world. There's still no stay-at-home order. Trump wants to reduce what little is being done after Easter. That's going to make the situation considerably worse.

Plenty of states have stay at home orders. Mine does. It isn’t clear to me the federal government has the authority to issue that kind of order, short of martial law. The US government isn’t identical to many other countries. States are like quasi-countries, legally, authority-wise, and culturally.

All true, but even with stay at home orders, not everyone stays home. Some people are essential workers and have to go to work. Other people go out for exercise, grocery shopping, etc. If those people have protective equipment available it is truly senseless to not wear it given the extreme danger.

Appropriate equipment yes, absolutely. But even doctors and nurses do not wear face shields routinely around hospitals. They are worn when performing particular procedures and circumstances that don’t apply to most situations even in hospitals.

SARS-CoV-2 is not a routine disease. HCWs are dropping like flies. They obviously not being adequately protected.

Because they’re dying doesn’t mean shields will help. I think the medically inclined people in this discussion are making reasoned arguments. You however are just appealing to hysteria.

I can imagine so many other more likely reasons for those deaths than face shield usage.

Face shields aren’t protective wear in public. Taking them away from doctors and nurses however does increase mortality for them and patients in general.
