Post-Acute COVID-19 Syndrome is New—But It’s Real

“Because post-COVID symptoms are such a new phenomenon, many patients find that friends, family, and even some physicians dismiss what they are experiencing. This can cause anxiety and depression on top of the physical burden. We know, however, that there are enormous numbers of patients who are presenting with these symptoms.

Many of our patients at the Center for Post-COVID Care are in their 20s to 40s, were relatively healthy, and had mild cases of COVID-19. Most were never hospitalized. Some patients come to the center with diagnosable damage from COVID-19, especially in the lungs. However, many have no clear cause for their symptoms—except that they had COVID-19. One theory is that the immune system is still in overdrive from fighting the virus during the infection. We are studying commonalities among patients, using data we have compiled on lungs, hearts, and brains from high resolution imaging. This will help us determine the effects of COVID-19. In many patients, we are also finding microscopic blood clots in the lungs, heart, liver, and the brain.

“The virus has many different effects on the body. Because the virus goes everywhere after it goes to the lungs, the immune response goes everywhere as well. So part of the damage is from the virus itself, but the immune system is also doing damage to your organs. Your immune system starts by activating cells that kill the virus. But sometimes these cells damage the organ the virus is next to, so it’s almost like collateral damage,” says Zijian Chen, MD, medical director of the Center for Post-COVID Care.
