Study details mechanisms underlying severe COVID-19

Severe COVID-19 arises in part from the SARS-CoV-2 virus’s impact on mitochondria, tiny oxygen-burning power plants in cells, which can help trigger a cascade of organ- and immune system-damaging events, suggests a study by investigators at Weill Cornell Medicine.
