Pro Tip: You can get Ivermectin at any feed store. After checking with my pharmacist friend, he says 1/2 of a tube taken over 5 days is the right dose for adults. A full tube will cost $8. We gave it to two sick family members and they started recovering the next day. My wife, who has lung problems due to being on a ventilator for Hantavirus when she was younger, was exposed to C19. We were concerned, so we gave it to her as well and she never got sick. YMMV,
