Had Covid last month and used Virx nasal spray. Kills the virus in the incubation stage while still in the upper respiratory. Woke with sore throat/fever. I had Virx at home and started using it right away. Covid positive day 2 and 3.
it worked for me. Sore throat gone by the next day. felt like I was getting sick but never did, small fever for a few days. Tested negative and swimming laps day 5.
