On July 23, the World Health Organization (WHO) declared monkeypox a "public health emergency of international concern". This is the second time in two years the W.H.O. has taken the step of declaring a global emergency. There have been more than 16,000 cases in 75 countries, overwhelmingly among men who have sex with men.
"We have an outbreak that has spread around the world rapidly, through new modes of transmission, about which we understand too little, and which meets the criteria in the International Health Regulations," Dr. Tedros Adhanom Ghebreyesus, director general of WHO, told reporters.
