If hydroxychloroquine + azithromycin is effective against covid-19, I wonder why it hasn’t been tried to treat other forms of flu with similar symptoms? Or maybe it has and I just haven’t seen mention of it. Or maybe they’re different enough it isn’t effective, but all I’ve heard is it’s very effective against malaria, which is spread by insect/animal bites and which mainly causes vomiting, fever, and headache - not respiratory symptoms.
I don't know, FDA? Everyone likes new drugs as there is little money in off patent stuff. Malaria is caused by parasites, and if you don't get them all, malaria becomes the gift that keeps on giving.
CDC declares in 2005 it is effective.
Chloroquine is a potent inhibitor of SARS coronavirus infection and spread.
Or "the cold"?
