Long Covid: What to Know About Persistent Symptoms of a Covid-19 Infection

Some people who have had Covid-19 still have symptoms that persist for weeks, months, or up to a year after infection, even though the illness was a mild case. Scientists, doctors and patients have long dubbed the disease Covid.

The World Health Organization in October defined long Covid as a condition in people with a probable or confirmed case of Covid-19 three months ago, with symptoms that last for at least two months and cannot be explained by another diagnosis. Symptoms can range from mild to debilitating, and the Biden administration said some Americans with long Covid may have a disability under civil rights laws protecting them from discrimination.
