Was given surfactant as an infant due to extreme prematurity, now recent lung ct shows inflammation, minimal bilateral scar and unspecific aveolar density. i also had covid recently. could this be due to the surfactant or covid and can it be reversed?

Surfactant is a product that mimics a natural one made in the lungs as it matures. I doubt it has anything to do with your issues 30 years later. What is common for those infants that needed surfactant to survive is residual lung scarring and sensitivity to respiratory illness for their lifetime. Early covid strains attacked deep lung tissues as their major target. Some injury improves/some remain

The recent episode of COVID-19 is perhaps more likely related, but. additional information would be helpful. Do you have chronic lung disease, asthma or COPD? The treatment for premature lung disease is quite effective and as the lung grows and develops the early symptoms often improve . Watch for signs of shortness of breath, cough and wheezing.
