In the US, the BA.5 Omicron subvariant accounts for approximately 80 percent of new infections

From the U.S. Centers for Disease Control and Prevention (CDC) 5 Omicron sub-variant, currently the dominant coronavirus strain in the US, accounts for about 80 percent of new Covid-19 infections in the country, according to the most recent data.

In the US, the BA.5 subvariant accounted for 77.9 percent of new infections in the last week ending July 16. This rate was 68.7 percent a week ago.

CDC data showed that another new subvariant, BA.4, accounted for 12.8 percent of new infections.

These two infectious subvariants currently account for more than 90 percent of new infections in the United States.

CDC data also revealed that confirmed cases of the two sub-variants have continued to rise since mid-May.

More contagious than previous variants of Omicron, these two sub-variants seem to evade protection from vaccines and previous infections more easily than most of their predecessors, according to health experts.
