First Clade I Monkeypox Case in USA in 2024 Highlights Travel Vaccination Needs
Monkeypox cases have been reported in several continents, including Europe, Asia, and the United States, with widespread outbreaks ongoing in Africa. The CDC has confirmed the first travel-associated case of clade I monkeypox in the USA in 2024. The global outbreak of clade II monkeypox, which began in 2022, continues at low levels worldwide.
Monkeypox is a viral infection that exists in two main clades, I and II. Clade I is prevalent in the Democratic Republic of Congo (DRC) and neighboring countries, while clade II has been spreading globally since 2022. The first known travel-associated case of clade I monkeypox in the USA was diagnosed by CDC specialists in 2024.
The CDC reported a case of travel-associated clade I monkeypox in the United States on November 15, 2024. This case highlights the importance of vaccination for travelers, especially those anticipating certain sexual activities while visiting countries with sustained spread of clade I monkeypox. The CDC recommends two doses of JYNNEOS for such travelers, as the current vaccine guidance for preventing clade II monkeypox also provides protection against clade I.
The global spread of monkeypox, particularly clade I, underscores the need for vigilance and vaccination among travelers. The CDC's guidance on vaccination remains crucial for preventing the further spread of both clades. Anyone planning to travel to affected areas should consult the CDC's recommendations to protect themselves and others.
