Overview
- The Health Department confirmed a clade I infection in a recent international traveler and issued a health advisory to providers.
- Officials report no known local transmission or additional clade I cases in the five boroughs, saying the current risk is low.
- Clade I is associated with more severe illness than clade II, which fueled about 4,000 New York City cases in 2022.
- The city urges at-risk people to complete the two-dose JYNNEOS series with doses at least 28 days apart; those who previously had mpox do not need vaccination.
- People who should consider vaccination include men who have sex with men, trans and nonbinary people, travelers to areas with mpox activity, and recent close contacts within 14 days; vaccine sites are listed at nyc.gov/mpox or by calling 311.
