Mpox Cases Rebound as Officials Issue Summer Health Warnings

Public health officials are preparing contingency plans in case mpox infections rebound in the coming months.
Although mpox cases have declined since last summer, 21 new infections were reported this week, primarily among men who have sex with men.
The virus that causes mpox disease may have evolved to partially evade vaccines, though initial doses of Jynneos vaccine still offer some protection.
The Biden administration is weighing whether to change vaccination strategies but for now is urging at-risk groups to get two vaccine doses.
Ten counties have at least a 50 percent chance of new mpox outbreaks this summer, according to CDC modeling, though officials hope vaccines and treatments will limit spread.
