Amid 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.
What is EG.5 , aka Eris?
EG.5 is a descendant of the omicron XBB sublineage of the virus (specifically, XBB.1.9.2). It has an extra mutation in its spike protein, according to a WHO risk evaluation report.
"When we look at its sequence, EG.5 is really similar to the other XBB variants that are circulating right now, with a couple of small changes," Dr. Andrew Pekosz, a virologist at Johns Hopkins University, tells TODAY.com.
The WHO added EG. 5 to its list of variants under monitoring on July 19, 2023, but the variant was first detected in February 2023. "Scientists have known about this variant, and it’s been present in other countries, as well," says Pekosz.
The EG.5 variant is very similar to other omicron variants, which means it's highly transmissible, Dr. Albert Ko, an infectious disease physician and professor at Yale School of Public Health, tells TODAY.com.
However, EG.5
is likely more transmissible than other XBB variants, Dr. Sharon Nachman, chief of the division of pediatric infectious diseases at Stony Brook Children’s Hospital, tells TODAY.com.
All COVID-19 tests — including PCR tests performed by a medical provider and rapid at-home antigen tests sold over-the-counter — should be detecting EG.5, says Pekosz.Continue reading:
