Long after the acute infection fades, pieces of the virus behind COVID-19 can linger in the body and quietly sabotage the ...

COVID-19 was never just a hit-and-run infection, and the latest science shows why. Even after the active virus is gone, fragments of its genetic material and spike proteins can linger, assemble into ...

How long COVID develops is still largely unknown. New molecular connections are revealed in a recent study led by the Center ...
