Monkeypox outbreak in U.S. and Europe surprises scientists

Scientists who have monitored numerous outbreaks of monkeypox in Africa say they are baffled by the disease’s recent spread in Europe and North America.

Cases of the smallpox-related disease have previously been seen only among people with links to central and West Africa. But in the past week, Britain, Spain, Portugal, Italy, U.S., Sweden and Canada all reported infections, mostly in young men who hadn’t previously traveled to Africa.

France, Germany, Belgium and Australia confirmed their first cases of monkeypox on Friday.

“I’m stunned by this. Every day I wake up and there are more countries infected,” said Oyewale Tomori, a virologist who formerly headed the Nigerian Academy of Science.

“This is not the kind of spread we’ve seen in West Africa, so there may be something new happening in the West,” he said.

Monkeypox typically causes fever, chills, a rash and lesions on the face or genitals. WHO estimates the disease is fatal for up to one in 10 people, but smallpox vaccines are protective and some antiviral drugs are being developed.

One of the theories British health officials are exploring is whether the disease is being sexually transmitted.

On Friday, Britain’s Health Security Agency reported 11 new monkeypox cases, saying that “a notable proportion” of the most recent infections in the U.K. and Europe have been in young men with no history of travel to Africa who were gay, bisexual or had sex with men.

Authorities in Spain and Portugal also said their cases were in young men who mostly had sex with other men and said those cases were picked up when the men turned up with lesions at sexual health clinics.

Scientists said that while it’s possible the outbreak’s first patient caught the disease while in Africa, what’s happening now is exceptional.

“We’ve never seen anything like what’s happening in Europe,” said Christian Happi, director of the African Centre of Excellence for Genomics of Infectious Diseases.

Happi also pointed out that the suspension of smallpox vaccination campaigns after the disease was eradicated in 1980 might inadvertently be helping monkeypox spread. Smallpox vaccines also protect against monkeypox, but mass immunization was stopped decades ago.
