The number of U.S. mpox cases has more than doubled compared with last year, and the federal Centers for Disease Control and Prevention has been urging clinicians across states to encourage vaccinations for those at risk.
As of May 25, the nation had seen a roughly 150% increase in cases of the disease formerly known as monkeypox — from 434 at that time last year to 1,089 this year, according to the CDC. About a third of the cases are in New York state, New York City (which the CDC reports separately), New Jersey and Pennsylvania.
