They also are learning, or should be learning, about how to treat covid so that people don't die.
At Elmhurst in Queens, NYC, NY, they were figuring out ways to get as many people on ventilators as possible.
They put people on fentanyl, on ventilators, and they all died. Presumably, because ventilators = death, they stopped doing that (but not necessarily). People who have covid could, in theory, be given hydroxychloroquine immediately.
More is known now than 3 months ago. In theory, that knowledge could be used to avoid deaths.
