What should I know about Mpox and HIV?

As of December 1, the CDC had tallied nearly 30,000 mpox cases in the United States and more than 81,000 cases worldwide. A large majority of cases have been among gay, bisexual and other men who have sex with men, and sexual contact is the most commonly reported transmission route.

Mpox cases fell by more than 90% after peaking in late July and early August, according to Daskalakis. Experts attribute the drop to a combination of factors, including immunity in the initially infected group, rapid vaccine uptake and behavior change. A CDC survey conducted in August found that half of men who have sex with men had made changes, such as having fewer sex partners.
