>>The chloroquine has bad side effects & it's not going to work.
We'll know soon enough.
FWIW I was a recent medical graduate (doctor) when I took chloroquine in the '80s because I'd done my homework and judged it safe. Mind you, I also took a Hep A vaccine extracted from human blood which was all that was available at the time (and at huge cost, as you can imagine- luckily in my case covered by the dreaded nationalized health servce). That stopped once AIDS became a thing and as is so often the case with young dreams, I never did make it back to Africa or need chloroquine again. Until now, maybe?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
