While I am open to the possibility that hydroxychloroquinone can prevent Covid, what I, at least, have not seen yet, is a study that breaks down the following (and I welcome any missed news that corrects any aspect of this):
1. How widespread is the benefit? Is it absolute, or a percentage? If it's a percentage, what percentage is that? What is the size of the sample?
2. How widespread are the risks, relative to the benefits, for a general public?
3. Among the population of lupus patients, how many would be expected to contract the virus, and what is the margin of error?
4. Have any untreated lupus patients contracted the virus?
5. How reliable are the accounts at the root of this issue? Has there been a truly scientific study of whether it is actually the fact that lupus patients taking this drug are actually less likely to contract the disease, with a reasonable correction for the conditions under which they live?
6. If immunity is gained by taking the drug, what effect does it have on communicability? Does it make you disease free, or does it make you a symptom-free carrier? If the latter, does the supply of the drug make it possible to decrease total Covid cases, or does it make it likely that there will be more?
So far we have the suggestion that lupus patients aren't getting the virus, but we have not determined just why. It's likely that the drug is responsible, but unless some lupus patients without the drug are getting it, we can't be sure.
