Scientists worry virus variant may push up COVID cases in US
March 23, 2022
With coronavirus cases rising in parts of Europe and Asia, scientists worry that an extra-contagious version of the omicron variant may soon push cases up in the United States too.
Experts are also keeping their eyes on another mutant: a rare delta-omicron hybrid that they say doesn't pose much of a threat right now but shows how wily the coronavirus can be.
The U.S. will likely see an uptick in cases caused by the omicron descendant BA.2 starting in the next few weeks, according to Dr. Eric Topol, head of Scripps Research Translational Institute.
