Dominant COVID-19 Strain BA.2 , Not Showing Signs of Causing Surge in US.
CNN reports that BA.2, the now dominant strain of coronavirus in the United States, is living up to its designation as the "stealth variant.".
A subvariant of Omicron, BA.2 is
responsible for 3 out of 4 positive
COVID-19 cases in the United States.
Still, experts say there is no indication
yet that the subvariant could cause
another surge in infections.
As BA.2 dominates other coronavirus
strains, the overall number of cases in the
country has decreased.
This is a clear example of how these two trends are not necessarily tied together. , Jessica Justman, an epidemiologist at Columbia University's
Mailman School of Public Health, via CNN.
Health experts say it's unclear why the
United States hasn't experienced the
same increase in new infections as Europe.
One theory revolves around estimates that 95%
of Americans have differing levels of immunity.
Per the CDC, nearly
45% of Americans currently have infection-related antibodies.
But such high levels of immunity
have come at a steep cost.
According to data from Johns Hopkins University, over 980,000 Americans
have died due to COVID-19.
