The U.S. measles tally has grown to 4,080, according to the latest CDC figures cited in a MedPage Today news roundup. The count marks a continued rise in cases as health officials track multiple outbreaks across the country.

Pennsylvania is a notable hotspot: its record-breaking outbreak contributes more than a fourth of the national toll. The source does not specify the exact number of cases in Pennsylvania, only that it exceeds a quarter of the total.

The source, a daily summary of health news, offers no additional context on vaccination rates, age groups, or hospitalizations. It also does not indicate whether the case count is expected to climb further.
