A possible biomarker for long COVID suggests some people with the condition never fully cleared the virus

The virus circulating in the current outbreak has mutated 50 times in the past four years

When SARS-CoV-2 lingers in the body, it accumulates many of the same mutations seen in the most dangerous global variants. What can scientists do with this knowledge?
