Going with exists too. Had flu plenty and this was NOTHING like I have ever experienced. Brother and I live in same house and we both came down with same symptoms last year this time. Down hard for a week. Took ivermectin at the very onset and hit the z-stack regimen... did not seem to help much for me. Brother did not take it and we seemed to be down and feeling like shit for the same time. Lost sense of taste and smell for over 4 months. Major loss of appetite....weirdly the only two items that I felt like consuming were boost drinks and cold cut sandwiches. No lung problems though as others have noted...
