Researchers want to understand whether COVID-19 virus can stay in the lungs long after someone recovers from infection. This study will examine lung tissue from patients undergoing lung surgery — some who previously had COVID-19 and some who never did — to look for any remaining virus particles and understand what might happen to them over time.
Some people who recover from COVID-19 continue to experience breathing problems or other symptoms for weeks or months afterward. By studying actual lung tissue, scientists hope to learn whether leftover virus particles might be causing these long-term effects and how the body clears the virus completely.

If you qualify, you would participate as part of your already-scheduled lung surgery. Researchers would collect a small sample of lung tissue that is removed during your medically necessary surgery and examine it in the laboratory to look for any remaining COVID-19 virus. There are no additional visits or procedures beyond your scheduled surgery — the tissue collection happens during the operation your doctor already recommended.
