Measles cases are increasing in Missouri, including in the St. Louis metro area, prompting Arkansas families to evaluate their preventive measures against the highly contagious virus.

Dr. Adam Hurst, a pediatrician with the New York Institute of Technology College of Osteopathic Medicine at Arkansas State University, emphasized that the measles vaccine is the best defense. "The vaccine has been available for decades and has been proven safe and effective," Hurst explained.

Measles spreads easily from person to person, especially in crowded environments. Dr. Hurst noted that travel to high-risk areas can introduce the virus to other regions. Disturbingly, measles symptoms—such as fever and runny nose—can resemble those of a common cold or other respiratory illnesses, complicating early detection.

Hurst offered a situational reminder, saying, "Unfortunately, knowing it’s in the St. Louis area and if you were at a Cardinals game and you didn’t know you got exposed, and all of a sudden you have a high fever, you have a runny nose, [these are] common symptoms that we’re seeing right now because respiratory illnesses are coming up."

If parents suspect exposure or observe concerning symptoms, Hurst advised them to contact a medical provider. He also stressed the importance of consulting with pediatricians about vaccine recommendations, addressing any concerns, and trusting their medical provider's guidance. "The biggest question you need to be asking is to your doctor — to your child’s doctor — ‘Can they be vaccinated? Do they need to be vaccinated?’" he said.

The Centers for Disease Control and Prevention (CDC) reports that no measles cases have been confirmed in Arkansas this year. In 2025, the state saw eight measles cases.

Health officials continue to emphasize the vaccine and booster as critical tools in protecting children. With cases nearby in Missouri, Arkansas families are urged to remain vigilant and prioritize vaccinations for eligible children.

For more information, residents are encouraged to contact their healthcare providers.
