Anons,
I‘ve read numerous anecdotes of people thinking they had wuhanvirus possibly as far back as November/December 2019. I had an illness in early November (Nov 5-15) that seemed to be the worst illness I had which I originally figured was acute bronchitis. I took an antibodies test on Tuesday and the results were back in under 24 hours.
I tested negative so I will definitely give a lot less weight to anyone who thinks they had the corona back in Nov/Dec. you can request the antibodies test through your doctor or pay $120 for it. https://questdirect.questdiagnostics.com/products/covid-19-immune-response/b580e541-78a5-48a6-b17b-7bad949dcb57
