SACRAMENTO — Gov. Gavin Newsom of California declared a state of emergency on Monday to address a monkeypox outbreak, making the state the third in four days to elevate its public health response to the rapidly spreading disease.
The declaration followed similar actions by New York on Friday and Illinois on Monday, and by the city of San Francisco on Thursday. Mayor Eric Adams of New York also declared a local emergency on Monday.
“California is working urgently across all levels of government to slow the spread of monkeypox, leveraging our robust testing, contact tracing and community partnerships strengthened during the pandemic to ensure that those most at risk are our focus for vaccines, treatment and outreach,” Mr. Newsom said in a statement.
“We’ll continue to work with the federal government to secure more vaccines, raise awareness about reducing risk and stand with the L.G.B.T.Q. community fighting stigmatization,” he added.
The moves, which help streamline and coordinate the monkeypox response among different levels of government, come amid an uptick in infections as well as increasingly vocal complaints about the public health response.
What to Know About the Monkeypox Virus
Nearly 6,000 cases of monkeypox have been reported nationally since May, according to the Centers for Disease Control and Prevention, with nearly half of them reported in California, Illinois and New York. The World Health Organization has already declared the virus to be a global health emergency.
No deaths have been reported so far in the United States, and monkeypox is rarely fatal, but the rash caused by the virus has led to intense pain in some patients. The virus spreads primarily via prolonged physical contact, but it can also be transmitted via shared linens and clothing, health officials say.
Men who have sex with men have so far made up about 99 percent of the confirmed cases. Public health officials emphasize that the virus can spread to anyone who has prolonged skin-to-skin contact with a person who has the rash.
The U.S. case count is among the highest in the world, and health officials say the figure is almost certainly an underestimate.
Federal health officials say they have not yet declared a health emergency at the national level in part because monkeypox is a known disease with tests, vaccines and treatments available.
But as the virus has spread and scientists have gathered research, the emerging picture has been a bit more complicated than in past outbreaks, and pressure has intensified for more aggressive measures.
Last week, President Biden’s health secretary urged states and municipalities to take more initiative, noting that most public health powers in the United States are concentrated at local levels.
“We don’t control public health in the 50 states, in the territories and in the tribal jurisdictions,” Xavier Becerra, the secretary of health and human services, said in response to a reporter’s question about whether the virus could be eliminated. “We rely on our partnership to work with them. They need to work with us.”
California’s emergency declaration will allow Emergency Medical Services workers to administer federally approved monkeypox vaccines.
Gov. Kathy Hochul of New York issued an emergency declaration on Friday, saying the move would pressure the federal health officials to send additional monkeypox vaccines to the state. On Monday, Gov. J.B. Pritzker of Illinois followed suit, calling monkeypox “a rare but potentially serious disease that requires the full mobilization of all available public health resources.”
Mr. Pritzker added that the effort would “ensure our L.G.B.T. Q.+ community has the resources they need to stay safe while ensuring members are not stigmatized as they access critical health care.”
