WASHINGTON — President Joe Biden informed Congress on Monday that he will end the twin national emergencies for addressing COVID-19 on May 11, as most of the world has returned closer to normalcy nearly three years after they were first declared.

The move to end the national emergency and public health emergency declarations would formally restructure the federal coronavirus response to treat the virus as an endemic threat to public health that can be managed through agencies’ normal authorities.

It comes as lawmakers have already ended elements of the emergencies that kept millions of Americans insured during the pandemic. Combined with the drawdown of most federal COVID-19 relief money, it would also shift the development of vaccines and treatments away from the direct management of the federal government.
