I've had covid three times, and the last bout will keep resurfacing if I don't nebulize regularly. I use a solution of peroxide, silver and iodine. Do a search for an article on it by Mercola. I also inhale eucalyptus oil fumes to relax the cytokine storm. I've never had much fever though.

Unfortunately I can't take IVM because of a porous blood-brain barrier due to Lyme and coinfections. But the paste did no better or worse than the tablets in that regard, so they're probably equally effective.
