March 20, 2025 – Columbus, Ohio – The Ohio Department of Health (ODH) has confirmed the state’s first measles case of the year in an unvaccinated adult from Ashtabula County. The individual had contact with a recent international traveler, raising concerns about potential exposure and the importance of vaccination.
ODH is working closely with the Ashtabula County Health Department to track possible contacts and encourage vaccinations.
“This case serves as a stark reminder of the need for full vaccination,” said ODH Director Dr. Bruce Vanderhoff. “Measles can be serious, but it is preventable. I urge all Ohioans to ensure they and their children are up to date on their vaccinations.”
Rising Measles Cases & Risks
Measles outbreaks have been increasing worldwide, with current cases reported in Texas and New Mexico. Ohio previously experienced a major outbreak in 2022 with 90 cases, followed by a smaller number in 2023 and 2024.
Measles is highly contagious, spreading through coughing and sneezing. If unprotected, 9 out of 10 people exposed to the virus will become infected. The virus can linger in the air for up to two hours, making vaccination the best defense.
The Importance of the MMR Vaccine
The MMR vaccine, which protects against measles, mumps, and rubella, is 97% effective with two doses. The CDC recommends:
✔️ First dose at 12-15 months
✔️ Second dose at 4-6 years
✔️ Adults born after 1957 who are unvaccinated should also receive the vaccine
Measles Symptoms & Complications
Early symptoms include:
🔹 High fever
🔹 Cough, runny nose, and red, watery eyes
🔹 Rash that spreads from the face down the body
Measles can lead to serious complications, including pneumonia, ear infections, and in severe cases, death—especially in young children, pregnant women, and those with weakened immune systems.
Dr. Vanderhoff recently held a news conference urging parents to ensure their children are immunized, particularly as cases rise in other states. The full video is available on the ODH YouTube channel.
