Measles outbreaks are continuing to surge across the United States, pushing the national case count to alarming levels. With 1,563 confirmed cases of measles so far this year, 2025 is on track to break records, marking the highest number of cases since the disease was declared eliminated in the U.S. more than 25 years ago. Although a deadly outbreak in Texas ended in August, other regions of the country are now grappling with rising case numbers.
The resurgence of measles has experts on edge, as the highly contagious disease is mostly preventable with the MMR (measles, mumps, and rubella) vaccine. Unfortunately, declining vaccination rates and growing vaccine hesitancy are fueling these outbreaks, which are now posing a significant threat to public health.
The Scope of the Problem
Since the end of August 2025, there has been an average of 27 new measles cases reported each week, according to the Centers for Disease Control and Prevention (CDC). The situation is particularly alarming because before this year, the U.S. had only experienced 10 large outbreaks of measles (defined as over 50 related cases) since measles was declared eliminated in 2000. However, this year, there have already been three large outbreaks, and the total number of cases continues to climb.
In Ohio, Minnesota, and South Carolina, new outbreaks are contributing to the rising case count. In South Carolina, more than 150 unvaccinated children were placed under quarantine after being exposed to measles in schools. In Utah and Arizona, a significant outbreak along the border has already infected over 90 people, with numbers expected to grow.
The current national situation is the direct result of the steady decline in vaccination rates across the country. Experts warn that the spread of measles will only continue if vaccination coverage remains insufficient, particularly in regions where skepticism around vaccines is on the rise.
Ongoing Outbreaks and the Role of Vaccine Hesitancy
The measles outbreaks are a vivid reminder of the dangers of vaccine hesitancy and misinformation. Dr. Leisha Nolen, Utah’s state epidemiologist, explained that the ongoing outbreaks in her state are primarily concentrated in the southern region but are spreading to other areas. “We are starting to see now people get infected even at the very north end of our state,” Nolen said. “So I do think that this is going to continue to spread in different communities.”
In Spartanburg County, South Carolina, one of the lowest vaccination areas in the state, a significant outbreak has led to over 150 children being quarantined. South Carolina’s state epidemiologist, Dr. Linda Bell, noted that students who were exposed to measles and had not been vaccinated had a 90% chance of becoming infected. The quarantine protocols, which include excluding unvaccinated children until the risk of transmission has passed, have been put in place to prevent further spread.
The low vaccination rates in Spartanburg County are reflective of a broader trend across the U.S., where vaccination coverage has been steadily falling. For the 2024 school year, only 92.5% of U.S. kindergartners received the MMR vaccine, falling below the critical 95% threshold needed to prevent widespread transmission of measles. This is the fifth consecutive year that vaccination rates have dropped, setting the stage for future outbreaks.
Experts argue that these outbreaks are directly linked to the growing number of people who have not vaccinated their children or themselves. Dr. Scott Harris, president of the Association of State and Territorial Health Officials, stated, “When you have multiple cases happening, particularly with those numbers, it’s only possible because you have susceptible individuals.”
According to the CDC, 97% of the measles cases in the Texas outbreak earlier this year involved individuals who had not received one or both doses of the MMR vaccine, highlighting the critical role of vaccination in preventing outbreaks.
The Financial and Logistical Toll on Health Departments
The cost of responding to these outbreaks is straining local health departments across the country. Dr. Caitlin Rivers, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, emphasized the significant burden on health departments already stretched thin due to budget cuts and staff shortages. The resources required to manage a measles outbreak are substantial, including staffing quarantines, conducting contact tracing, and providing education on vaccination.
“It’s incredibly expensive and demanding for local health departments to respond to measles threats,” Rivers said. “Health departments are already stretched thin by budget constraints and staff attrition. Adding measles outbreaks to their workload is draining the reserves of even the best-resourced departments.”
In Utah, public health officials are using wastewater monitoring to track the spread of the virus, identifying areas with low vaccination rates and heightened risk. In these areas, health officials are working to raise awareness about the importance of vaccination and encourage parents to get their children vaccinated. However, vaccine misinformation and hesitancy remain significant barriers to reaching higher vaccination rates.
Federal Response and Leadership Concerns
As measles cases continue to rise, some public health experts are critical of the federal government’s response to the crisis, particularly under the leadership of Robert F. Kennedy Jr., the Secretary of the U.S. Department of Health and Human Services. While Kennedy has publicly supported vaccination, his handling of the situation has been controversial. Critics argue that his rhetoric on vaccines, particularly his downplaying of the importance of the MMR vaccine and his promotion of alternative therapies, has contributed to the current public health challenges.
Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, has been vocal in his criticism. “We’re in the midst of a measles epidemic,” Offit said. “We should have an administration that stands up clearly and definitively and holds press conferences saying, ‘Vaccinate your children. These are preventable illnesses.’”
Public trust in federal health leadership has been eroded in recent months, with polls showing growing disapproval of Kennedy’s handling of vaccine policy. Experts argue that stronger leadership and a clear, consistent message on the importance of vaccination are essential to reversing the current trends.
The Path Forward
To prevent further outbreaks and return to a state of measles elimination, experts agree that increased vaccination efforts are critical. Dr. Harris emphasized the need for a unified, nationwide approach to tackling vaccine hesitancy, particularly in communities with low vaccination coverage.
“We need to make sure that we’re educating people about the importance of vaccines and the risks of not vaccinating their children,” Harris said. “Measles is preventable, but we need to make sure that people understand the consequences of not getting vaccinated.”
Public health officials are continuing to monitor the situation closely, and efforts are underway to increase awareness and vaccination coverage. However, the ongoing outbreaks are a stark reminder that complacency in vaccination efforts can lead to devastating consequences, particularly for vulnerable populations.
Conclusion
The rise in measles cases across the U.S. serves as a wake-up call about the dangers of declining vaccination rates and growing vaccine hesitancy. While measles was once eliminated in the U.S., the current surge in cases is evidence that the fight against preventable diseases is far from over. With the right leadership, public education, and a renewed commitment to vaccination, the U.S. can work to curb this alarming trend and protect future generations from the dangers of measles.
