Secret Reservoir of COVID Virus Found Within Body Cells

Researchers at the Institute of Liver and Biliary Sciences in New Delhi discovered a hidden reservoir of the COVID-19 virus within extracellular vesicles (EVs), microscopic particles released by cells. Even in individuals testing negative via RT-PCR, SARS-CoV-2 RNA was found in EVs, suggesting a potential source for recurrent infections and an unrecognized transmission route.
