What to know about Eris, the new COVID-19 subvariant sweeping the US

Amid a summer uptick in COVID-19 cases, a new COVID subvariant, EG.5, also referred to as Eris, has emerged and become the dominant strain in the United States. Many are wondering if this new COVID variant is causing different symptoms.

EG.5 now accounts for the largest proportion of COVID-19 infections in the country compared to any other variant, according to the U.S. Centers for Disease Control and Prevention.

On Wednesday, Aug. 9, the World Health Organization classified EG.5 as a variant of interest as cases increase globally.

The EG.5 variant quickly overtook the prevailing omicron XBB strains in the U.S. last month.

Over a two-week period ending on Aug. 5, EG.5 made up an estimated 17.3% of new confirmed COVID-19 cases in the U.S., up from 12% two weeks prior, according to the latest CDC estimates.
