US Experiences Over 1,200 Measles Cases in 2025 Amid Outbreaks in Iowa and Beyond

The United States has reported more than 1,200 confirmed cases of measles so far in 2025, reflecting a concerning resurgence of the highly contagious disease. While the national weekly count has remained below 20 cases, localized outbreaks continue to emerge across various states. Notably, Iowa announced its first outbreak this year, adding to several other regional flare-ups.

In Texas, the outbreak remains significant, with a total of 750 cases reported across 35 counties, predominantly in West Texas. The outbreak began in a close-knit Mennonite community in Gaines County, which accounts for over half of the state's cases. Since late January, the county has seen nearly 2% of its residents infected, with 413 cases so far. Tragically, an 8-year-old child who was unvaccinated died in Texas due to measles pulmonary failure, highlighting the severe risks associated with the disease.

New Mexico continues to see steady numbers, with 81 cases statewide, primarily in Lea County. The outbreak has resulted in seven hospitalizations and one death in an unvaccinated adult. Similarly, Oklahoma has recorded 17 cases, though specific counties have not been disclosed.

Arizona reports four cases all linked to a single source in Navajo County, with all affected individuals unvaccinated and recently traveling internationally. Colorado has reported 16 cases in 2025, including an outbreak involving 10 related cases linked to a flight at Denver International Airport, and additional cases in Boulder County among vaccinated individuals.

Georgia has a small ongoing outbreak with three confirmed cases in metro Atlanta, part of a total six cases this year. Illinois has seen a four- to eight-case outbreak in the southern part of the state, which has since stabilized.

Iowa reports six total cases; four are part of an outbreak within a single household in Johnson County. Meanwhile, Montana has recorded 22 cases, including the first in the state in 35 years, with cases concentrated in Gallatin County.

North Dakota has experienced 34 cases, mostly among unvaccinated individuals, with some cases linked to recent international travel. Cases have also appeared in other states, including Alaska, Arkansas, California, Florida, Hawaii, and others, often linked to international exposure.

The resurgence of measles is largely attributed to declining vaccination rates nationwide, which have fallen below the 95% threshold necessary for herd immunity. The MMR (measles, mumps, and rubella) vaccine remains highly effective, with recommended doses for children and booster shots for adults when necessary. Despite the availability of the vaccine, misinformation and vaccine hesitancy have contributed to gaps in immunity.

Measles spreads through airborne particles, causing symptoms like high fever, runny nose, cough, red eyes, and a characteristic rash. While most children recover, complications such as pneumonia, blindness, and brain swelling can be severe and sometimes fatal. Currently, there is no specific antiviral treatment; management focuses on symptom relief and prevention of complications.

Health officials continue to urge vaccination as the most effective measure against measles. Maintaining high immunization coverage is critical to preventing further outbreaks and safeguarding public health. Source: https://medicalxpress.com/news/2025-06-measles-tops-cases-iowa-outbreak.html
