Covid Eris: What to know about new variant EG.5 dominating U.S. cases

COVID infections and hospitalizations are on the rise in the U.S., Europe and Asia. Health officials are pointing at the EG.5 "Eris" coronavirus, a subvariant of the Omicron lineage that originally emerged November of 2021.

The World Health Organization (WHO) classified EG.5, which has been nicknamed by some as "Eris", as a "variant of interest," indicating that it should be more closely watched than others because of mutations that might make it more contagious or severe.

Still, the WHO said at this time it does not seem to pose more of a threat to public health than other variants and that there "is no evidence of an increase in disease severity directly associated with EG.5."

EG.5 had been found in more than 50 countries as of August 8, according to the WHO. It is the most common and fastest growing COVID-19 subvariant in the U.S., estimated to be responsible for around 17% of current COVID cases, according to the CDC.
