It's very interesting to see such skin issues treated with ivermectin, although they are fundamentally a cleanliness issue of skin, clothes, and carpet.

Regarding HCQ, do I have a story to tell. Early in the Covid years, I had its symptoms twice. This was before any vaccine or tests. The first time was from a coworker, and the second time from a stairwell while unmasked. Both times, nothing would fix it, but pure CQ did. This was no fish tank cleaned. It was a proper CQ medicine at 250 mg/day for two days, then repeated again after a week for another two days. The only side effects were very minor visual blurriness which resolved on its own within 3 months, and cardiac arrhythmia which resolved using atenolol. The cardiac arrhythmia could just have been an effect of Covid itself for all I know. Note that I do take quercetin which is one of the few agents that is necessary to get CQ or HCQ to do its magic, failing which it could not work for Covid. Later strains of Covid became weaker and the vaccine also protected, so I didn't need it for future reinfections.
