The Centers for Disease Control and Prevention (CDC) confirmed 61 new US measles cases today and 2,231 for the year, as Virginia has become the country’s latest hot spot.
Last year the CDC recorded 2,289 infections for the entire year, so the nation is just 58 cases short of that as we pass the midpoint of the year. The 2025 total was the most since 1991, and the United States is now on track to lose its measles elimination status that it gained in 2000.
All but 13 of this year’s cases were locally acquired, with the rest related to travel outside the country. Of the total, 20% of infections are in children age 5 and under, and 70% involve kids and young adults to age 19. Six percent of patients have been hospitalized, compared with 11% in 2025. Among all measles patients, 93% are unvaccinated or have unknown vaccine status.
No measles deaths have been reported this year, compared with three in 2025.
Virginia reports 22 new cases
Measles activity in Virginia has increased, with 22 new measles cases confirmed this week and 177 for the year. On June 26, the Virginia Department of Health (VDH) said that the measles outbreak that began in May in Buckingham County has expanded to include Cumberland County. “The number of outbreak cases has risen substantially in Buckingham County and in some neighboring areas,” the VDH said.
Virginia had only five confirmed measles cases last year.

Pennsylvania, meanwhile, confirmed 12 new cases this week and 101 total, and Utah lists five new cases, for a total of 507. The CDC measles map, however, shows 103 cases in Pennsylvania and 516 in Utah.
This week Iowa reported its first measles case of the year, in a vaccinated woman who had traveled internationally.
South Carolina continues to have the most cases this year, with 670, according to the CDC map, but the large outbreak in the Upstate region is now over. Texas has reported the third most cases for 2026, with 182. After Virginia comes Florida, with 141 cases. The Florida Department of Health, however, lists 155 measles cases through July 4.

- The number of cases in Michigan’s cyclosporiasis outbreak has risen by more than 300 to 1,562, according to an update today from the Michigan Department of Health and Human Services. Forty-four patients have been hospitalized to date in the outbreak of the intestinal illness, which causes diarrhea. The source of the outbreak, caused by Cyclospora parasites, has not yet been identified.
- A cluster of Legionnaires’ disease cases in two neighborhoods in New York City’s Upper East Side has grown to 46 cases, with 22 patients hospitalized, the New York City Health Department said yesterday in an update. The department is continuing to investigate the source of the pneumonia-like illness, which can occur when people breathe in water vapor that contains Legionella bacteria. Officials said in the update that the outbreak is not linked to issues with plumbing systems in any buildings in the two neighborhoods, and that residents can continue to drink tap water, bathe, shower, cook, and use their air conditioners.
- Two more New World screwworm (NWS) infections have been reported this week in Texas, according to the US Department of Agriculture’s Animal and Plant Health Inspection Service dashboard. Both detections, one in Brewster County and one in Crockett County, are in cattle. Since the first detection of the parasitic fly infection on June 3, there have been 34 cases—33 in Texas and one in New Mexico. Twenty of the cases are active, which means the infested animal is still undergoing treatment and wound management until free of NWS myiasis (maggot infection in living tissue).
