"No evidence" new COVID variant LB.1 causes more severe disease, CDC says

There are no signs so far that the new LB.1 variant is causing more severe disease in COVID-19 patients, the Centers for Disease Control and Prevention says, as infections have begun to accelerate in this summer's wave around the country.

The LB.1 variant currently makes up 17.5% of new COVID cases, the CDC projected Friday, and could be on track to overtake its sibling, the KP.3 variant, which has also been growing in recent weeks.

"There is currently no evidence that KP.3 or LB.1 cause more severe disease. CDC will continue to track SARS-CoV-2 variants and is working to better understand the potential impact on public health," CDC spokesperson David Daigle said in a statement.
