U.S. Leads Globally in Known Monkeypox Cases, CDC Says

The U.S. has reported more than 3,400 confirmed or suspected monkeypox cases, federal data showed, becoming the country with the most known infections since the onset of the global health emergency.

The rise in cases comes as the U.S. expands testing capacity, broadening the ability to spot new infections, but also as the global outbreak continues to grow. Some public-health experts said rising transmission heightens the chances a broader population will face the risk of infections as the opportunity to slow and potentially stop the outbreak is fading.
