Measles outbreaks hitting a 30-year high in the U.S.

Measles outbreaks hitting a 30-year high in the U.S.

In a stark reminder of the importance of vaccination, North America is currently grappling with a resurgence of measles cases, with the United States experiencing its worst year for the disease in over three decades. According to the Centers for Disease Control and Prevention (CDC), as of 2025, the national case count has surpassed the 2019 count of 1,274 cases, with 1,288 cases reported nationwide.

The situation is particularly dire in states like Texas and California, where low vaccination rates, active outbreaks, and international travel connections are contributing to the spread of the disease. In Texas, the epicenter of the outbreak, West Texas has reported over 750 cases, making it one of the largest contributors to the national surge. California, while not specifically highlighted as a major hotspot, is also among the states reporting measles cases.

The decline in vaccination rates, particularly after the COVID-19 pandemic, is a significant factor in the outbreaks. A recent study found that childhood vaccination rates against measles fell in nearly 80% of U.S. counties with available data. This drop in immunization coverage leaves communities vulnerable to outbreaks, as they lack sufficient herd immunity to prevent the spread of measles.

The measles, mumps, and rubella (MMR) vaccine, which is 97% effective at preventing measles after two doses, is a crucial tool in combating the disease. However, misinformation about vaccines can lead to reduced vaccination rates, further increasing the risk of outbreaks. Public health efforts to counter misinformation are crucial in maintaining high vaccination rates.

The outbreaks in North America are not isolated incidents. Canada and Mexico are also experiencing major measles outbreaks. In Chihuahua state, Mexico, 2,966 cases have been reported, while Ontario, Canada, has seen 2,223 cases, and Alberta, Canada, has reported 1,230 cases. These outbreaks are linked to large Mennonite communities, where historically low vaccination rates and distrust of government have been observed.

The increase in measles cases is a worrying development, as the disease can have severe consequences. Three people have died from measles in the U.S., with two deaths occurring in Texas and one in New Mexico. Additionally, dozens of people have been hospitalized due to measles in the U.S.

Lauren Gardner, leader of Johns Hopkins University's independent measles and COVID tracking databases, warns that if the virus continues to spread for 12 months, the U.S. could lose its status of having eliminated the vaccine-preventable illness. Gardner views the situation as indicative of a problem with vaccination attitudes in the U.S.

Addressing the measles outbreaks requires a multifaceted approach, including promoting vaccination, enhancing public health messaging, and ensuring access to healthcare services. By working together, public health officials, community leaders, and individuals can help protect themselves and their communities from the devastating effects of measles.
