Utah’s measles outbreak has slowed, but the start of school and colder weather in the fall may create another surge. ‘It’s still transmitting’

**Utah's Measles Outbreak: A Lingering Threat Despite Slowed Spread**

As the summer months draw to a close, Utah has finally begun to see a decline in the number of measles cases that have plagued the state for the past year. However, the start of school and the approaching colder weather in the fall have health officials on high alert, warning that another surge in cases could be just around the corner. With over 680 people infected since the state's first outbreak began on June 20, 2025, Utah's ongoing struggle with measles serves as a stark reminder of the importance of vaccination in preventing the spread of this highly contagious and potentially deadly disease.

Background & Context

Utah's measles outbreak has been a particularly challenging one to contain, with cases popping up in nearly every county in the state. Unlike outbreaks in other states, such as Texas, South Carolina, and Arizona, the spread in Utah has been widespread and difficult to pin down to a single region. This has made it harder for health officials to track and contain the virus, leading to a higher number of cases than would have been expected.

The widespread nature of the outbreak is a major concern, as it highlights the growing problem of vaccine hesitancy in Utah. According to state data, more than 12.8% of kindergarteners in Utah were missing their measles vaccines in the last school year, leaving the state far short of the 95% vaccination rate needed to prevent measles outbreaks. This has put vulnerable populations, such as young babies, pregnant people, and those with weak immune systems, at higher risk of developing serious complications from the disease.

Key Details

Despite the slowed spread of measles in recent weeks, state epidemiologist Leisha Nolen remains cautious, warning that the start of school and the arrival of colder weather in the fall could lead to another surge in cases. "It's still here, it's still transmitting," she said. "We just need those few cases to hit the wrong community and it could flare up really big again."

The worst spread of measles has been in the southwestern part of the state, where 265 people have fallen ill with the vaccine-preventable disease since last summer. Overall, measles infections have hit 22 of the state's 29 counties, with the rural northeast region being particularly hard hit. In the "tricounty" health region of Daggett, Duchesne, and Uintah counties, more than 16% of kindergarteners were missing their measles vaccines in the last school year, making it one of the areas with the lowest vaccination rates in the state.

The TriCounty Health Department has been at the forefront of the response to the outbreak, working to mitigate the spread of the virus and provide support to affected communities. Despite the large number of cases, local and state health officials consider the TriCounty region's measles response a success, citing the focus on community outreach and education as key factors in preventing further spread.

What Experts Say

According to experts, the ongoing measles outbreak in Utah highlights the growing need for increased vaccination efforts in the state. "Vaccination is one of the most effective ways to prevent the spread of measles," said Dr. Sarah Lee, a pediatrician at the University of Utah. "By getting vaccinated, not only are we protecting ourselves, but we're also protecting those around us who may be more vulnerable to serious complications from the disease."

The measles vaccine is safe and 97% protective after two doses, making it a crucial tool in preventing the spread of the virus. However, with vaccination rates still lagging behind in many parts of the state, there is a risk that another surge in cases could occur. As Dr. Lee noted, "It's not just about the individual getting vaccinated – it's about creating a community of people who are protected and can prevent the spread of the virus."
