The WHO and the Biden administration extended the public health emergency for COVID-19, saying the virus is still considered a serious health threat.

The agency cautioned countries in recent weeks against dropping COVID surveillance measures, saying that doing so would cripple efforts to accurately track the spread of the virus.
