How long does COVID-19 linger in your body? New report offers clues.
A comprehensive study found that viral remnants can survive for months after infection in certain people, perhaps causing some symptoms of long COVID.
The study suggests that when the genetic material of the virus, called RNA, lingers in the body longer than 14 days, patients may face worse disease outcomes, experience delirium, stay longer in the hospital, and have a higher risk of dying from COVID-19 compared with those who cleared the virus rapidly. The persistence of the virus may also play a role in long COVID, the debilitating suite of symptoms that can last for months. Estimates suggest between 7.7 and 23 million people in the United States alone are now affected by long COVID.
Without immunity from vaccination or a previous infection, SARS-CoV-2—the virus that causes COVID-19—replicates and spreads throughout the body and is shed through the nose,
