I disagree. Something was developed under gain of function. My wife had it in Mar 2020 and couldn’t smell a blooming shrub in our yard you can smell half a block away. Her sense of smell changed, though not as dramatically as OP, for months. She tested positive for antibodies via blood test 4x over 9 mo. I think the variants and the testing is fake and gay but there really is something out there designed to take out the obese primarily. Some of its flu, but some of it is very unique symptoms. We’ve all had flu, bronchitis, sinusitis, allergies, etc…this was a very unique symptom unlike anything else.
