My understanding is the Ivermectin has to be given early and before someone is admitted to the hospital otherwise it is not as effective. You must start therapeutics including regeneron AS SOON AS YOU CAN. Go to an urgent care and get tested RIGHT AWAY if you have symptoms (especially coughing) and at least ask them to prescribe a z-pack or prednisone or budesonide. DO NOT wait several days to see your own doctor if you have symptoms!
I don’t know. We knew our friend had COVID so my mom asked doc about it virtually. They tested her. From there as we all got sick we knew what it was. I got tested myself but from then on the rest just assumed and took it as it came. We got better.
(My MIL, unfortunately, did not, and died.)
