也是因为周围有人有类似的病症

我不是学医的，但我的理解是COVID造成inflammation，身体内部的肿胀压迫到了神经，导致免疫系统出毛病(autoimmune diseases).

这个病很麻烦。虽然Biden宣布已经over了，但我周围还不断有朋友染上，这个坛子上也继续有人分享最近染上的体验。基于得病人的总数占了总人口的百分之好几十，Long COVID的绝对病者数字会很高。

Researchers are beginning to understand how the human immune system contributes to the varied responses to COVID-19. Autoantibodies—immune system proteins that mistakenly target the body’s own tissues—may underlie some of this variation. Autoantibodies are found in a wide range of autoimmune diseases, such as lupus and rheumatoid arthritis. Many people with low levels of autoantibodies in their blood have no obvious symptoms.
