Anyone who was in the UPMC Chautauqua emergency department in Jamestown, New York, during two windows in late September may have been exposed to measles. The Chautauqua County Health Department said in an October 1 alert that people who tested positive for measles were at the hospital, at 207 Foote Ave., on the night of Saturday, September 26, and during the day on Tuesday, September 29. The department said the people who tested positive do not live in Chautauqua County. It has not said how many people were infected.
For western New York families, the alert is practical. Emergency departments often serve the people most likely to develop measles complications, including young children, pregnant patients, and people with weakened immune systems. A parent who brought a sick child in that Saturday night now has a few weeks of watching to do.
Two Emergency Room Windows and Two Monitoring Deadlines
The first exposure window ran from 9 p.m. Saturday, September 26, through 1 a.m. Sunday, September 27. The second ran from 9 a.m. to 4 p.m. on Tuesday, September 29. The county said anyone present during the first window should watch for symptoms through Saturday, October 17, and anyone present during the second should watch through Tuesday, October 20. Both dates fall 21 days after the exposure.
Measles does not show up right away. The CDC's clinical overview of measles says the rash usually appears about 14 days after exposure. Fever, cough, runny nose, and red, watery eyes come first, followed by a rash that starts on the head and spreads down the body.
Even a brief visit can count. "The virus can remain in the air for up to two hours after an infected person has left an area," the department said.
Officials stressed that most people are likely protected. "Many people in our community are protected against measles because they have been vaccinated or have measles immunity. The risk of developing measles from these potential exposures is considered low," the health department said, as reported by WKBW and other local outlets.
Checking Immunity Records for Kids, Parents, and Grandparents
The county's guidance gives families a clear way to sort out who needs to worry. A person is generally considered immune if they have records of two doses of a measles vaccine, such as the measles, mumps, and rubella (MMR) vaccine; a blood test showing immunity or lab confirmation of a past measles infection; or a birth year before 1957.
For many households, the first job is paperwork, not panic. Parents can check school or pediatrician records. Adults can ask their primary care office or call the county health department at 716-753-4491. Anyone without proof of immunity should ask a clinician whether a blood test or vaccine dose makes sense.
Some family members carry more risk than others. The CDC lists children under 5, adults over 20, pregnant women, and people with weakened immune systems as the groups most likely to develop complications. Babies too young for their first MMR dose depend on the immunity of the people around them.
Local vaccination coverage leaves some room for concern. According to the county, 85.6% of Chautauqua County children ages 24 to 35 months had received one MMR dose before their second birthday as of January 1, 2026. The county has recorded three laboratory-confirmed measles cases in 2026, according to local radio station WRFA.
Free MMR Shots and Calling Ahead Before Care
Cost does not have to be a barrier. The health department offers free MMR vaccines at its Mayville office Monday through Friday, from 8:30 a.m. to 4:30 p.m. It is also running mobile health clinics at locations around the county from October 2 through October 29.
If symptoms appear, the county's key instruction is to call before walking in. "If you become sick, call your healthcare provider or emergency department before going for care," the department said. That call lets staff keep a possibly contagious person out of a crowded waiting room, the kind of shared space this alert describes. The county also advises people to stay away from public places while sick.
The alert comes during a heavy measles year nationally. The CDC counted 3,659 confirmed U.S. measles cases in 2026 as of September 24, including two deaths. New York posts updates on its state measles dashboard, which is updated each Tuesday with cases through the prior Saturday and covers the state outside New York City.
For now, the county considers the risk low, and the steps are simple: check records, watch for symptoms through October 17 or October 20, and call ahead if illness appears.
