Measles Cases Resurge in New York: Health Officials Urge Vaccination

Recent Measles Cases Confirmed in Ontario County

In Ontario County, New York, public health officials have reported a confirmed case of measles stemming from late March. The individual, who recently traveled from Ontario, Canada, tested positive for the virus and has since recovered after self-quarantining throughout April. Currently, there are no additional cases reported, but public health authorities remain vigilant in monitoring the situation.

Statewide Increase in Measles Cases

The New York State Department of Health has warned about a significant rise in measles cases, now totaling eight reported cases for the year, including three new cases involving children under five years old from Orange County. These children had also traveled internationally. The state health department is actively collaborating with local healthcare providers to investigate these outbreaks and keep the public informed.

Health Advisory and Prevention Measures

State Health Commissioner Dr. James McDonald emphasized the highly contagious nature of measles, which can lead to severe complications such as pneumonia and encephalitis. He reiterated the importance of the measles, mumps, and rubella (MMR) vaccination, stating that one dose offers 93% protection, while two doses boost efficacy to 97%.

• Travel Advisory: The health department issued a travel advisory on April 2, encouraging travelers to ensure they are fully vaccinated at least two weeks prior to their departure.
• Symptoms and Quarantine: Symptoms of measles include high fever, cough, runny nose, and red, watery eyes, followed by a rash. Those who have been exposed should self-quarantine for 21 days to prevent further spread.
• Reporting Suspected Cases: Healthcare providers have been urged to promptly report any suspected cases to local health authorities.

National Context

As of May 1, the CDC has recorded 935 cases of measles across the United States in 2025, marking a dramatic increase compared to the previous year. Once declared eliminated in 2000 due to effective vaccination campaigns, measles has seen a resurgence in various states, particularly affecting young, unvaccinated children.

Call to Action for Public Health Safety

Health officials reiterate the necessity for all individuals, especially young children, to be up-to-date on their measles vaccinations. New Yorkers are advised to be vigilant and informed about health advisories, particularly when traveling with unvaccinated children.

Furthermore, healthcare providers in areas experiencing outbreaks, such as Orange County, are advised to enhance screening practices for patients, ensuring that potential cases are managed swiftly and effectively to curb further transmission.

As public health officials work to combat this resurgence of measles, community awareness and proactive vaccination remain key to preventing a public health crisis.
