The rapid spread of mpox, formerly called monkeypox, in African countries constitutes a global health emergency, the World Health Organization declared on Wednesday.
This is the second time in three years that the W.H.O. has designated an mpox epidemic as a global emergency. It previously did so in July 2022.
That outbreak went on to affect nearly 100,000 people, primarily gay and bisexual men, in 116 countries, and killed about 200 people.
The threat this time is deadlier. Since the beginning of this year, the Democratic Republic of Congo alone has reported more than 14,000 mpox cases and 524 deaths.
