Mpox screening in high- risk populations finds no asymptomatic cases

Summary: The magnitude of the 2022 monkeypox virus outbreak has exceeded any previous outbreak, and undiagnosed infections may be driving the epidemic. A study found four men attending a Belgian sexual health clinic to be infected with monkeypox. One man had a painful rash while the other three were asymptomatic, but their infections were confirmed through clinical examination. These findings suggest that undiagnosed cases of monkeypox could contribute to the transmission and scale of the 2022 outbreak.
