I’ve read that Ivermectin does all of that too...
We haven’t used ivermectin, but the antiviral a loved one got worked very well.
You just have to get treatment within 72 hours, IIRC, of onset of symptoms.
Hasn’t been a recurrence, either.
Oddly enough the docs pushing the vaxxes in our neck of the woods never mention therapeutics.
Just vaxxes.
Go figure.
