COVID-19 cases have trended down in the United States since a peak of infections in January 2022, according to the Centers for Disease Control and Prevention (CDC). Now, health experts warn of a potential uptick of infections in the coming months due to the emergence of BA.2—a new variant of Omicron, which was the leading variant causing COVID-19 cases during the coronavirus pandemic’s spike in infections this winter.
“The variant has been in the United States for about the past two months and it has been slowly increasing in proportion compared to BA.1 [Omicron].”
—CDC Director Dr. Rochelle Walensky
