So far, 557 people have been registered with the monkeypox virus in Berlin (as of Monday evening), Gote informed. Nationwide, there are 838 registered cases, meaning that two-thirds of all monkeypox infections in Germany were registered in the federal capital. According to the Robert Koch Institute, the pathogen is mostly transmitted from person to person through close physical contact. "In Berlin, as far as we know, the disease is currently spreading exclusively among men who have sex with men," Gote said. But all population groups could become infected.
