Gottlieb, a member of the board at Pfizer, reviewed the state of the monkeypox outbreak while talking with Margaret Brennan on CBS News's Face the Nation.
“I think the window for getting control and containing it probably has closed, and if it hasn't closed, it's certainly starting to close,” Gottlieb said.
There have been 1,814 affirmed cases of monkeypox across the United States, according to the Centers for Disease Control and Prevention. "Monkeypox is a rare disease caused by infection with the monkeypox virus," per the agency. "Monkeypox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Monkeypox symptoms are similar to smallpox symptoms but milder, and monkeypox is rarely fatal. Monkeypox is not related to chickenpox."

The spread has happened more than two years after the start of the COVID-19 pandemic, which remains another health concern as a dominant Omicron subvariant appears to be more vaccine-resistant.
Gottlieb also said issues with containment come from not testing a wide enough focus population and that there may be too much emphasis on testing gay men.

“We're probably detecting just a fraction of the actual cases because we had, for a long time, a very narrow case definition, and by and large, we're looking in a community of men who have sex with men and at STD clinics," Gottlieb said. "We're looking there, finding cases there, but it's a fact there are cases outside that community right now. We're not picking them up because we're not looking there. This has spread more broadly in the community. I wouldn't be surprised if there are thousands of cases now.”
