Omicron's BA.2 sub-variant behind 72% of COVID cases in US: CDC
- A weekly increase of 15% was seen in the US
- New infections in Asia have triggered new concerns of another COVID wave
- BA.2 sub-variant became dominant in the US late last month
United States Centers for Disease Control and Prevention provided an update on the omicron variant's spread across the country. The health agency revealed that 72% of all new COVID-19 cases in America were a result of the BA.2 sub-variant.
In comparison to last week's record, the BA.2 sub-variant of omicron seems to be gaining momentum in the United States after increasing by 15%. Last week's measurement was 57.3%.
According to reports from Reuters citing estimates from the Centers for Disease Control and Prevention, the seven-day average of infections as of April 1 stood at 26,106. The number saw a slight dip from last week, measuring at 26,309.
Even though the United States has largely removed all major COVID-19 restrictions, spiking cases in Asia and Europe have triggered concerns. The United States, however, has seen a sharp decline in new infections since January after hitting its peak.
Overall COVID-19 cases in the United States have dropped sharply after hitting record levels in January, but a resurgence in cases in parts of Asia and Europe has raised concerns that another wave could follow in the United States. The country's health experts, however, believe it is unlikely.
On a global scale, the new COVID-19 variant makes up about 86% of cases, according to reports from Reuters citing data from the World Health Organization.
The BA.2 variant is known to be more transmissible than the BA.1 and BA.1.1 omicron sub-variants, however, the evidence so far suggests that it is no more likely to cause severe disease.
Scientists acknowledge that the wide availability of vaccines and treatments puts the nation in a better place than when the pandemic began, and that monitoring has come a long way.
The BA.2 variant became dominant in the United States late last month.
