The Biden administration plans to end the Covid public health emergency this spring, which will mark a major turning point in the U.S. response to pandemic.

The White House, in a statement Monday, said it would terminate on May 11 both the public health and national emergencies first declared by the Trump administration in 2020.

The statement from the Office of Management and Budget came in response to two pieces of legislation introduced by House Republicans seeking to end both emergency declarations.

OMB said abruptly ending the emergency declarations in the way laid out in the Republican legislation would “create wide-ranging chaos and uncertainty throughout the health care system.” The Republican legislation has no chance of becoming law.

The emergency declarations have enabled hospitals and nursing homes to respond more flexibly when faced with spikes in patient volume during Covid surges.

Enrollment in Medicaid has also surged during the public health emergency because Congress basically barred states from disenrolling people from the program.

A provision tucked in federal spending legislation passed in December allows states to start disenrolling people from Medicaid again in April.

OMB said ending the declarations without giving hospitals time to adjust would lead to “disruptions in care and payment delays, and many facilities around the country will experience revenue losses.”

It would also “sow confusion and chaos” in the process of winding down the Medicaid coverage protections, OMB said.

The Health and Human Services Department has promised to give states 60 days notice before ending the public health emergency so the health-care system has time to prepare for a return to normal.

The public health emergency has been extended every 90 days since January 2020 as the virus has evolved into new variants and thrown repeated curveballs over the past three years. HHS just extended the public emergency again earlier this month.

Covid has killed more than 1 million people in the U.S. since 2020. Deaths have dropped dramatically since the pandemic peak during winter 2021, but nearly 4,000 people are still succumbing to the virus every week.

Although the emergency declarations remain in place, the federal response to the pandemic has been weakened as funding has dried up. Congress has failed for months to pass a White House request for $22.5 billion in additional funding for the Covid response.

The White House is also planning to transition the Covid vaccines to the private market in the near future, though the exact timing is unclear. This means the cost of the vaccines would be covered by patients’ insurance policies rather than the federal government.

Moderna and Pfizer have both said they may charge as much as $130 per dose of vaccine, quadruple what the federal government pays.
