Mpox is down, but US cities could be at risk for summertime outbreaks

The mpox health emergency has ended, but U.S. health officials are aiming to prevent a repeat of last year’s outbreaks.

Mpox infections exploded early in the summer of 2022 in the wake of Pride gatherings. More than 30,000 U.S. cases were reported last year, most of them spread during sexual contact between gay and bisexual men. About 40 people died.

With Pride events planned across the country in the coming weeks, health officials and event organizers say they are optimistic that this year infections will be fewer and less severe. A bigger supply of vaccine, more people with immunity and readier access to a drug to treat mpox are among the reasons.
