The United States has designated monkeypox a public health emergency as the number of cases of the disease, which has primarily affected men who have sex with men, continues to climb.

The news was first reported by the New York Times. Secretary of Health & Human Services Xavier Becerra announced he’d declare monkeypox a public health emergency in a conference call on Thursday with reporters. “I will be declaring a public health emergency on monkeypox,” Becerra said. “We’re prepared to take our response to the next level in addressing this virus, and we urge every American to take monkeypox seriously and to take responsibility to help us tackle this virus.” Robert Fenton, the recently appointed White House National Monkeypox Response Coordinator, said amid criticism the Biden administration has been too slow in responding to monkeypox the new declaration would open up opportunities in confronting the outbreak. “The public health emergency will allow us to explore additional strategies to get vaccines and treatments more quickly out in the affected communities, and it will allow us to get more data from jurisdictions so we can effectively track the suffering,” Fenton said.

During the call, Becerra said an estimated 6,600 cases of monkeypox have been reported throughout the country, and more than 600,000 vaccines have been delivered to localities.
