Ohio Reports Third Measles Outbreak in 2026 Amid Unvaccinated Cases and National Surge

One documented exposure site linked to the outbreak is Smokey Lane Stables in Sugarcreek, with the Tuscarawas County case believed to have been exposed there on July 17.
Measles can persist in the air for up to two hours after an infected person coughs or sneezes, broadening the window for potential exposure beyond direct contact.
The four cases in this outbreak range from 4 to 30 years old, and all are unvaccinated, underscoring vulnerabilities in vaccine uptake among young people.
The Ohio cluster meets the CDC threshold for an outbreak, defined as three or more related cases.
Nationwide in 2026, measles cases have reached 2,295—the highest annual total since 1991—with Ohio reporting 15 cases so far in 2026 and earlier outbreaks in Cuyahoga and Franklin counties.
Ohio has declared its third measles outbreak of 2026, with four confirmed cases spread across Ashtabula and Tuscarawas counties. Canton Repository reported that every infected person is unvaccinated, and their ages range from 4 to 30 years old.
The outbreak comes as measles cases across the United States hit a 35-year high. Nationwide, 2,295 cases have been confirmed so far in 2026 — the most in a single year since 1991, according to Lancaster Eagle-Gazette.
Ohio health director Bruce Vanderhoff declared the outbreak after three cases emerged in Ashtabula County and one in Tuscarawas County, according to Medical Daily. Under CDC rules, three or more linked cases qualify as an outbreak. Ohio has now recorded 15 measles cases in 2026 alone, following earlier outbreaks in Cuyahoga and Franklin counties.
One confirmed exposure site is Smokey Lane Stables in Sugarcreek. The Tuscarawas County patient is believed to have been exposed there on July 17, according to Canton Repository. Health officials are now reaching out to anyone who may have visited that location during the contagious window.
Health officials are warning that measles is one of the most contagious diseases known. The virus can linger in the air for up to two hours after an infected person coughs or sneezes. That means people can get sick even if the infected person has already left the room.
Anyone exposed should watch for symptoms for 21 days. The News-Messenger reported that officials advise staying home if symptoms appear. People should also call a doctor before going to a clinic or hospital, so staff can prepare and stop the virus from spreading further.
Measles was declared eliminated in the US in 2000. But vaccination rates have slipped in many communities, falling below the 95% threshold needed for herd immunity — meaning enough people are vaccinated to protect everyone. When that threshold drops, outbreaks become far more likely, according to Lancaster Eagle-Gazette.
Ohio's case count has climbed steadily through 2025 and into 2026 as part of that national trend. Every patient in this latest outbreak was unvaccinated, reinforcing what officials have said all year: vaccination is the clearest way to prevent infection and stop outbreaks before they grow.
Mahoning Matters reported that Ohio health officials are conducting exposure notifications to find anyone who may have come into contact with infected individuals. The MMR vaccine — which protects against measles, mumps, and rubella — is available through doctors and local health departments.
Vanderhoff has pointed to vaccination as the state's best defense. Two doses of the MMR vaccine are about 97% effective at preventing measles. Officials say children and adults who are not up to date on their shots should act quickly, especially those who may have visited exposure sites in recent weeks.
