Pneumonia is just one of the slew of side effects from COVID-19.
The National Heart, Lung, and Blood Institute describes pneumonia as an infection in one or both of the lungs that causes the alveoli (air sacs) to fill with fluid. With double pneumonia, both lungs are affected.
Richard Watkins, M.D., a Northeast Ohio Medical University associate professor of internal medicine who specializes in infectious disease, tells Prevention readers, “Bacterial pneumonia more commonly involves one lung and viral often is a diffuse pattern in both lungs. X-rays and CT scans in patients with COVID-19 usually show both lungs are involved.”
