Coronavirus: 75% of people with long COVID take a year to recover, finds study

The researchers also found a link in the recovery of patients and the levels of autoantibodies and cytokines in their systems. Cytokines are crucial in controlling the growth and activity of other immune system cells and blood cells. They signal the immune system to do its job.

Now, the researchers found that the patients who recovered had a reduction in autoantibodies and cytokines, matched by their symptoms improving. However, those with persistent symptoms had elevated antibody and cytokine levels even after one year from the initial infection.

“Sometimes, while the body is fighting the virus, the immune system gets so amped up that, in addition to making antibodies that kill the virus, it can produce those that attack the host,” senior author Dr. Manali Mukherjee, an assistant Professor of Medicine at McMaster University said in a statement.
