也是因為周圍有人有類似的病症

我不是學醫的，但我的理解是COVID造成inflammation，身體內部的腫脹壓迫到了神經，導致免疫係統出毛病(autoimmune diseases).

這個病很麻煩。雖然Biden宣布已經over了，但我周圍還不斷有朋友染上，這個壇子上也繼續有人分享最近染上的體驗。基於得病人的總數占了總人口的百分之好幾十，Long COVID的絕對病者數字會很高。

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.
