Monkeypox Caseload in U.S. Approaches World’s Highest

The U.S. has reported about 3,600 confirmed or suspected monkeypox cases, federal data showed, while vaulting near the top of the list of countries 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.
