Abstract

We examined 89 travel-related clade Ib monkeypox virus cases detected in 33 countries during August 2024-July 2025. Most cases were approximately men; about one third led to secondary transmission. Secondary transmission risk was highest among sexual, then household, contacts. Those groups should be the focus of response strategies and interventions.
