Health officials are investigating the monkeypox outbreak to determine if the virus acquired a mutation that makes it more transmissible or if superspreader events in Europe may be to blame for the current outbreak.
"Anytime the virus does something new, it catches our attention," says Dr. Richard Kennedy, co-director of Mayo Clinic's Vaccine Research Group.
Monkeypox is endemic in Central Africa. While outbreaks of monkeypox have occurred before, none has been this large.
