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 behavior at two recent mass events in Europe. 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.

Monkeypox has not previously triggered widespread outbreaks beyond Africa, where it is endemic in animals. “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.

That marks a significant departure from the disease’s typical pattern of spread in central and western Africa, where people are mainly infected by animals like wild rodents and primates and outbreaks have not spilled across borders.

A German government report to lawmakers, obtained by the AP, said it expected to see further cases and that the risk of catching monkeypox “mainly appears to lie with sexual contacts among men.” The four confirmed cases in Germany have been linked to exposure at “party events including on Gran Canaria and in Berlin, where sexual activity took place,” it said.

To date, WHO has recorded more than 90 cases of monkeypox in a dozen countries including Britain, Spain, Israel, France, Switzerland, the U.S. and Australia. On Monday, Denmark announced its first case, Portugal revised its total upwards to 37 and Italy reported one further infection.

Madrid’s senior health official said on Monday that the Spanish capital has recorded 30 confirmed cases so far.

Enrique Ruiz Escudero said authorities are investigating possible links between a recent Gay Pride event in the Canary Islands, which drew some 80,000 people, and cases at a Madrid sauna.

Heymann chaired an urgent meeting of WHO’s advisory group on infectious disease threats on Friday to assess the ongoing epidemic and said there was no evidence to suggest that monkeypox might have mutated into a more infectious form.

Monkeypox typically causes fever, chills, rash, and lesions on the face or genitals. It can be spread through close contact with an infected person or their clothing or bedsheets, but sexual transmission has not yet been documented.

Most people recover from the disease within several weeks without requiring hospitalization. Vaccines against smallpox, a related disease, are also effective in preventing monkeypox and some antiviral drugs are being developed.

In recent years, the disease has been fatal in up to 6% of infections, but no deaths have been reported among the current cases.

WHO said confirmed cases have so far been the less severe West African group of monkeypox viruses and appeared to be linked to a virus that was first detected in exported cases from Nigeria to Britain, Israel and Singapore in 2018-2019.

The UN agency said the outbreak is “a highly unusual event” and said the fact that cases are being seen in so many different countries suggests the disease may have been silently spreading for some time.
