(CNN) — The Biden administration is opening additional federally run free COVID-19 testing sites in six states across the country — Maine, Maryland, Nevada, Delaware, Texas and Washington — as the Omicron variant of the coronavirus continues to surge in the US.

“We have the tools we need to manage the surge in Omicron cases,” White House COVID-19 response coordinator Jeff Zients told reporters Wednesday, citing vaccinations and boosters, funding from the COVID relief package to help schools implement prevention measures and federal support for treatment and prevention.

The Biden administration, Zients said, “is deploying every available measure to help states communities and hospitals confront this Omicron challenge. Military doctors, nurses, and EMTs are now in place assisting local hospital staff and states across the country, with additional teams ready to deploy as needed.”

A White House official told CNN Wednesday that 13,546 National Guard personnel are currently deployed to support COVID-19 efforts, including approximately 700 medical personnel.
