The first handful of omicron cases in the United States have been mostly mild, with most patients reporting symptoms such as cough or a runny nose, according to a report from the Centers for Disease Control and Prevention.
The findings, published Friday, offer an early glimpse into how people might fare against the heavily mutated Covid-19 variant, now in at least 22 states, though health experts stress it's still too early to draw any strong conclusions on how it will spread in the country.
The agency's five-page report looked at 43 people in the U.S. with a confirmed case of the new strain, one of whom was hospitalized. More than half of the people were young, between the ages of 18 and 39.
