New York State Department of Health Issues Health Advisory on First Mpox Clade Ib Case Detected in New York

ALBANY, N.Y. (February 12, 2025) - The New York State Department of Health today issued a Health Advisory to health care providers about a travel associated mpox clade Ib case detected in New York, the first known mpox clade Ib case in New York State, including New York City. The specimen came from a symptomatic individual who recently traveled to Africa.

"The individual who contracted the virus is under the care of a physician and isolated until the full resolution of symptoms," State Health Commissioner Dr. James McDonald said. "There is no known local transmission of mpox clade Ib in the community where the individual lives or anywhere within New York State. The JYNNEOS vaccine, a two-dose vaccine series that works to prevent mpox, is expected to be effective against mpox clade Ib and available for individuals at risk with the standing order I signed last year. There is no immediate risk to the general public."
