According to US Centres for Disease Control and Prevention Director Rochelle Walensky, the Omicron variant of the coronavirus accounts for roughly 73 percent of Covid-19 cases across the country, which has reported a 25% increase in the seven-day average from the previous week, to about 149,300 infections per day.
In some locations, such as the eastern Atlantic states, parts of the Midwest, South, and northern Pacific states, Omicron variant cases account for up to 90% of total infections, Walensky told reporters at a White House briefing.
“This increase in Omicron proportion is exactly what we expected and planned for,” she said.
