WHO Declares Africa Mpox Outbreak a Global Health Emergency

THURSDAY, Aug. 15, 2024 (HealthDay News) — The World Health Organization on Wednesday made the rare move of declaring an ongoing African outbreak of mpox a global health emergency.

A new clade (strain) of the virus, plus its troubling spread throughout the Democratic Republic of Congo (DRC) and nearby countries in central Africa, drove the declaration, said WHO director general Dr. Tedros Adhanom Ghebreyesus.

“The detection and rapid spread of a new clade of mpox in eastern DRC, its detection in neighboring countries that had not previously reported mpox, and the potential for further spread within Africa and beyond is very worrying,” he said in a WHO news release.

According to the Africa Centers for Disease Control and Prevention, the new outbreak has led to more than 17,500 confirmed and presumed mpox cases and 524 deaths in 13 countries, some of which have never been affected by the disease before.

Most cases have occurred in the DRC, and women and children under the age of 15 appear to be most at risk.

The newly spotted strain has yet to have been identified in cases outside of Africa.

But the U.S. Centers for Disease Control and Prevention issued a alert last week that advised health care providers to be on the lookout for the new mpox strain in patients who have recently been in the Democratic Republic of Congo (DRC) or any neighboring country (Angola, Burundi, Central Africa).

Still, “due to the limited number of travelers and lack of direct commercial flights from DRC or its neighboring countries to the United States, the risk of clade I mpox importation to the United States is considered to be very low,” the CDC added.

Wednesday”s WHO declaration is meant to spur health agencies in countries worldwide to be on heightened alert for local cases, and to help supply vaccines, treatments and other resources to developing nations hit hard by the disease.

“We need concerted international action to stem this recent, novel outbreak,” Gregg Gonsalves, an epidemiologist at Yale University who served on the WHO’s mpox committee in 2022, told the New York Times.

The WHO announcement follows a declaration on Tuesday by the Africa Centers for Disease Control and Prevention that the outbreak is a “public health emergency of continental security.”

It”s the second time in three years the WHO has designated an mpox outbreak a global health emergency.

In July 2022, an outbreak that originated in Africa spread worldwide, affecting nearly 100,000 people, primarily gay and bisexual men across 116 countries and killing about 200 people, the Times reported.

What”s worrying in the new outbreak is that the death rate linked to the new strain of the disease appears higher: About 3 percent of those infected have died, instead of the 0.2 percent observed in the 2022 outbreak.
