The researchers found that repeat SARS-CoV-2 infections contribute significant additional risk of adverse health conditions in multiple organ systems.

Such outcomes include hospitalization; disorders affecting the lungs, heart, brain, and the body’s blood, musculoskeletal and gastrointestinal systems; and even death. Reinfection also contributes to diabetes, kidney disease and mental health issues.

The findings are published Nov. 10 in Nature Medicine.
