Abstract

We report clade Ib monkeypox virus infection in a patient who returned to Thailand from the Democratic Republic of the Congo, the subclade epicenter. Improved diagnostic testing, public health response, and surveillance systems for mpox are needed in Thailand, and preexposure mpox vaccination should be considered, especially for high-risk persons.

Keywords: Democratic Republic of the Congo; Thailand; clade Ib; monkeypox virus; mpox; public health; real-time PCR; sexually transmitted infections; viruses; zoonoses.
