US Nears 1,200 Measles Cases as Ohio Declares Outbreaks Over

As of June 2025, the United States is approaching a total of 1,200 confirmed cases of measles this year, according to the Centers for Disease Control and Prevention (CDC). Recently, Ohio health officials announced that three outbreaks in two counties have been contained and are now considered over, marking a significant milestone in regional efforts to control the disease.

Throughout 2025, the number of measles cases has remained relatively low, with fewer than 30 cases documented this week, reflecting improved vaccination coverage and public health initiatives. The outbreak in Texas, particularly in West Texas, remains notable, with a cumulative of 744 cases across 35 counties. The outbreak began in a close-knit Mennonite community in Gaines County, which accounts for more than half of the state's cases.

The Texas health department reported that 96 individuals have been hospitalized during this outbreak, with an 8-year-old child dying in April due to measles-related pulmonary failure, despite being unvaccinated. Another unvaccinated child, aged 6, also succumbed in late February.

In New Mexico, the total remains steady at 81 cases, with most infections occurring in Lea County. Seven individuals have been hospitalized, and an adult death was recorded in early March. Oklahoma reports 16 confirmed, and Arizona has four cases—all linked to recent international travel, with all affected being unvaccinated.

Canada's outbreaks persist as well, with Ontario experiencing over 2,000 cases from mid-October to June 10, including the first measles death in the region in 35 years. Alberta reports 868 cases, and Mexican authorities have documented 2,179 cases and four deaths in the state of Chihuahua.

Within the US, other states such as Illinois, Kansas, Montana, and North Dakota are experiencing localized outbreaks. For example, Montana has reported 20 cases—the first in 35 years—while North Dakota has 34 cases, primarily unvaccinated individuals.

Nationally, the CDC emphasizes that vaccination remains the most effective prevention method. The MMR vaccine, administered in two doses, is highly effective at preventing measles. Despite its availability, vaccination rates have declined nationwide due to vaccine hesitancy, leading to increased vulnerability.

Measles initially infects the respiratory tract before spreading through the bloodstream, causing symptoms such as high fever, cough, runny nose, watery eyes, and characteristic rash. The rash appears three to five days after initial symptoms, often accompanied by fever spikes exceeding 104°F. While most children recover, measles can cause severe complications including pneumonia, blindness, brain swelling, and death.

Currently, the majority of recent cases involve unvaccinated individuals, underscoring the importance of immunization. Health officials continue to monitor and respond to outbreaks while urging the public to ensure their vaccinations are up to date.
