I can't prove what the hell this stuff was we had back in August.. It did not feel natural and was a complete mix of bronchitis, strep symptoms, flu like achy bones joints, severe sinus cold headaches and yes nausea/vomiting BS. Random spikey fevers.. I don't know but I've never had a "flu" in the first week of August. My ivermectin and HCQ took effect within 12-24 hours though - it took 7 days to obtain this. My husband got it too, but his was fever of 101-103 for 15 days total. He lost 20 lbs and I lost 10. I lost my sense of taste and smell till almost Halloween. All I know is their POS test said "Covid-Sars" positive. We had to get them done for work in order to be paid for our time off. I'm saying - it's not natural - it didn't feel like a normal illness or like anything I had ever experienced. I thought I was getting better a then another damn symptom showed up for a couple of days (between day 5-6) which was nausea/vomiting. That was a 14 day trainwreck. Thank the Lord for our immune systems to fight this and an angel across state lines who prescribed the miracle drugs. It's something but not sure what..
