While COVID-19 rates in the U.S. are relatively low and are declining, The World Health Organization is keeping an eye on a new COVID-19 variant. The omicron subvariant XBB.1.16, known as "Arcturus," has been listed by the WHO as a variant under monitoring since March 22. Experts say this variant has a higher transmissibility rate than previous strains but doesn't appear to be more dangerous.
"It is causing increasing case counts in certain parts of the world, including India. We're not seeing high rates of XBB.1.16 yet in the United States, but it may become more prominent in coming weeks," says Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic.
He says experts are seeing new symptoms with the new variant.
