Only three states saw an increase in new cases last week
The number of new COVID-19 cases in the United States fell 23 percent last week, and the number of hospitalizations with the coronavirus fell 16 percent.
Both figures are down for the fifth week in a row.
But progress against the virus is threatened by several new strains, experts said, noting that wearing masks and keeping a social distance is still necessary.
About 4 percent of the nation’s cases are linked to the more contagious variant, which was first detected in Britain, said Dr. Rochelle Walenski, director of the Centers for Disease Control and Prevention.
“We have predictions that it could become the dominant strain by the end of March,” she said, speaking on CBS’s “Face the Country.”
There were more than 639,000 new cases of COVID-19 in the week of Feb. 7-14, according to a Reuters count based on state and county reports.
Compared to the previous week, the number of new cases increased in only three of the 50 states: Alaska, Nebraska, and South Dakota.
