The World Health Organization declared Wednesday that the increasing spread of mpox in Africa is a global health emergency, warning the virus might ultimately spill across international borders.
The announcement by WHO director-general Tedros Adhanom Ghebreyesus came after a meeting of the U.N. health agency’s emergency committee. The Africa Centers for Disease Control and Prevention declared mpox a public health emergency on the continent on Tuesday.
WHO said there have been more than 14,000 cases and 524 deaths in Africa this year, which already exceed last year’s figures.
So far, more than 96% of all cases and deaths are in a single country — Congo. Scientists are concerned by the spread of a new version of the disease there that might be more easily transmitted among people.
Here’s a look at what we know about mpox, and what might be done to contain it:
What is mpox?
Mpox, also known as monkeypox, was first identified by scientists in 1958 when there were outbreaks of a “pox-like” disease in monkeys. Until recently, most human cases were seen in people in central and West Africa who had close contact with infected animals.
In 2022, the virus was confirmed to spread via sex for the first time and triggered outbreaks in more than 70 countries across the world that had not previously reported mpox.
Mpox belongs to the same family of viruses as smallpox but causes milder symptoms like fever, chills and body aches. People with more serious cases can develop lesions on the face, hands, chest and genitals.
What’s happening in Africa that’s causing all this concern?
The number of cases has jumped dramatically. Last week, the Africa CDC reported that mpox has now been detected in at least 13 African countries. Compared with the same period last year, the agency said cases are up 160% and deaths have increased by 19%.
Earlier this year, scientists reported the emergence of a new form of mpox in a Congolese mining town that can kill up to 10% of people and may spread more easily.
Unlike in previous mpox outbreaks, where lesions were mostly seen on the chest, hands and feet, the new form of mpox causes milder symptoms and lesions on the genitals. That makes it harder to spot, meaning people might also sicken others without knowing they’re infected.
WHO said mpox was recently identified for the first time in four East African countries: Burundi, Kenya, Rwanda and Uganda. All of those outbreaks were linked to the epidemic in Congo. Tedros said there was concern for the further spread of the disease within Africa and beyond.
In the Ivory Coast and South Africa, health authorities have reported outbreaks of a different and less dangerous version of mpox that spread worldwide in 2022.
What does an emergency declaration mean?
WHO’s emergency declaration is meant to spur donor agencies and countries into action. But the global response to previous declarations has been mixed.
Africa CDC Director General Dr. Jean Kaseya said the agency’s declaration of a public health emergency was meant “to mobilize our institutions, our collective will and our resources to act swiftly and decisively.” He appealed to Africa’s international partners for help, saying that the escalating caseload in Africa had largely been ignored.
“It’s clear that current control strategies aren’t working and there is a clear need for more resources,” said Michael Marks, a professor of medicine at the London School of Hygiene and Tropical Medicine. “If a (global emergency declaration) is the mechanism to unlock these things, then it is warranted,” he said.
What’s different about the current outbreak in Africa compared to the 2022 epidemic?
During the global outbreak of mpox in 2022, gay and bisexual men made up the vast majority of cases and the virus was mostly spread through close contact, including sex.
Although some similar patterns have been seen in Africa, children under 15 now account for more than 70% of the mpox cases and 85% of deaths in Congo.
Ahead of its emergency meeting, Tedros said officials were dealing with several mpox outbreaks in various countries with “different modes of transmission and different levels of risk.”
“Stopping these outbreaks will require a tailored and comprehensive response,” he said.
