“We know monkeypox can spread when there is close contact with the lesions of someone who is infected, and it looks like sexual contact has now amplified that transmission,” said Heymann. Monkeypox has not previously triggered widespread outbreaks beyond Africa, where it is endemic in animals. In an interview with The Associated Press, Dr David Heymann, who formerly headed WHO's emergencies department, said the leading theory to explain the spread of the disease was sexual transmission among gay and bisexual men at two raves held in Spain and Belgium. A leading adviser to the World Health Organization described the unprecedented outbreak of the rare disease monkeypox in developed countries as “a random event” that might be explained by risky sexual behaviour at two recent mass events in Europe.
