中 了 covid 有 什么 症状 - 新冠后遗症有哪些表现？_腾讯新闻

The World Health Organization defines Long COVID as a condition that occurs in someone who had COVID, with symptoms that cannot be explained by another diagnosis, that last for two months or more.

It seems like most any ailment—from the expected, like fatigue, dry cough, and shortness of breath—to the obscure, like ear numbness, a sensation of "brain on fire," and hallucinations—could be symptoms, according to a landmark July study published in British medical journal The Lancet.

Researchers surveyed nearly 4,000 sufferers with confirmed or suspected COVID from nearly 60 countries, with illness of a month or longer.

However, the Mayo Clinic defines Long COVID as a set of symptoms stemming from COVID that persist for more than four weeks after diagnosis.
