Is monkeypox now a global crisis? WHO to consider again

African officials say they are already treating the continent's epidemic as an emergency. But experts elsewhere say an emergency declaration is unnecessary.

As the World Health Organization‘s emergency committee convenes Thursday to consider for the second time within weeks whether to declare monkeypox a global crisis, some scientists say the striking differences between the outbreaks in Africa and in developed countries will complicate any coordinated response.

African officials say they are already treating the continent’s epidemic as an emergency. But experts elsewhere say the mild version of monkeypox in Europe, North America and beyond makes an emergency declaration unnecessary even if the virus cannot be stopped. British officials recently downgraded their assessment of the disease, given its lack of severity.

Monkeypox has been entrenched for decades in parts of central and western Africa, where diseased wild animals occasionally infect people in rural areas in relatively contained epidemics. The disease in Europe, North America and beyond has circulated since at least May among gay and bisexual men. The epidemic in rich countries was likely triggered by sex at two raves in Spain and Belgium.

Some experts worry these and other differences could possibly deepen existing medical inequities between poor and wealthy nations.

There are now nearly 15,000 monkeypox cases worldwide. While the United States, Britain, Canada and other countries have bought millions of vaccines, none have gone to Africa, where a more severe version of monkeypox has already killed more than 70 people. Rich countries have not yet reported any monkeypox deaths.

“What’s happening in Africa is almost entirely separate from the outbreak in Europe and North America,” said Dr. Paul Hunter, a professor of medicine at Britain’s University of East Anglia who previously advised WHO on infectious diseases.

The U.N. health agency said this week that outside of Africa, 99% of all reported monkeypox cases are in men and of those, 98% are in men who have sex with other men. Still, the disease can infect anyone in close, physical contact with a monkeypox patient, regardless of their sexual orientation.

“In these very active gay sexual networks, you have men who really, really don’t want people to know what they’re doing and may not themselves always know who they are having sex with,” Hunter said.
