The whole hydroxychloroquine issue has not been helped by the French researcher, Raoult, who's been pushing it. I'd love to know what Mistigri has to say about it, as she is much more knowledgeable about such matters than I am.
My understanding is that there is some evidence that, if administered early, the drug can help alleviate symptoms.
Raoult's first test has been criticised because:
only 24 patients
all w mild symptoms
all selected by Raoult
no control group
Raoult didn't follow his own protocol
he published the results within 24hrs in a journal whose editor works with him (ie no proper peer review)
Raoult comes across as a complete tosser, convinced he is a unique genius surrounded by morons.
(Article here in Fr if you can stand it. As DS2 (10) pointed out, starting off an interview by saying, "Apparently you don't understand things the first time you're told them" and then coming out with stuff like, "I'm a worldwide star in my world" is unhelpful.)
The drug also has serious side effects.
One or two of Raoult's patients went into cardiac arrest, I think.
The fact that guy in the US drank fish tank cleaner is being cited as evidence (hydroxy)chloroquine is dangerous, but that's irrelevant. Other than as evidence, were it needed, that people who listen to Trump are not the brightest.
Here, the issue has fed conspiracy theorists: they are suggesting that because hydroxychloroquine is cheap and Macron is in the pocket of big pharma, the gvmt is refusing to allow widespread use so that big companies can look for a cure to flog at a higher price.
A hospital near me is using it, in conjunction with antibiotics.
