The point is in the retweet: that word "presumptive therapy" means it's being administered JUST IN CASE the patient has been exposed to loa loa.

If this is lethal fish bleach, why on earth would you risk giving it to potentially perfectly healthy people, especially for a condition that isn't spread through human hosts?

Answer: you'd do it if it posed virtually no serious risk whatsoever to a patient that didn't turn out to need it but could treat them for a potentially dangerous illness.

But it's so dangerous- this thing they're giving refugees and asylum seekers that potentially don't even need it- that we can't get it, and you're instantly banned from social media for even mentioning it in the same ZIP code as COVID.

THAT'S the point.
