Individuals with compromised immunity and persistent COVID-19 infections can harbor drug-resistant variants of the SARS-CoV-2 virus, which have the potential to spread to the general population, a study by Weill Cornell Medicine, the College of Veterinary Medicine at Cornell University and the National Institutes of Health’s National Institute of Allergy and Infectious Diseases found.

Certain gut-dwelling fungi flourish in severe cases of COVID-19, amplifying the excessive inflammation that drives this disease while also causing long-lasting changes in the immune system, according to a new study led by investigators at Weill Cornell Medicine and NewYork-Presbyterian.
