The question is not what causes Covid-19? We know it is caused by the virus, SARS-CoV-2. And we know quite a lot about the virus and the disease. Thousands of studies and articles have been published on this virus and disease to-date. The question is what causes a particular version of Covid-19, in which the disease continues indefinitely. Usually, a mild case lasts 1 to 3 weeks, a moderate case lasts 2 to 4 weeks, and a severe case can last well over a month. But the “longhaulers” type of Covid is not severe, but moderate, and yet it is not cleared within a month or so. Some “longhaulers” have been sick since March or April, and it’s now August.
It turns out that this hypothesis was first proposed by William Petri, MD, PhD. of Univ. of Virginia Medical School in this article here. And that just increases my surety about the hypothesis.
