WATERLOO – Local health officials have confirmed a case of measles in an unvaccinated Seneca County resident who recently returned from travel to Pennsylvania.
The resident was admitted to Cayuga Medical Center on Thursday, August 13, where diagnostic samples were collected and sent to the state Department of Health’s Wadsworth Laboratory. Following confirmation of the infection, the patient was discharged to isolate and recover at home. County and state health officials are actively conducting contact tracing to identify and notify anyone who may have been exposed.
Key information regarding symptoms, transmission, and public safety guidelines includes:
- Regional Context: Officials noted that approximately 15 measles cases have been confirmed outside New York City this year, including a recent case in neighboring Tioga County.
- Symptoms & Timeline: Symptoms typically appear 7 to 14 days after exposure (and up to 21 days). Initial signs include high fever, cough, runny nose, red eyes, and light sensitivity, often followed by small bluish-white spots inside the mouth and a blotchy red rash spreading from the face downwards.
- High Contagiousness: Measles spreads through the air via coughing or sneezing and can remain infectious in enclosed airspace for up to two hours after an infected individual leaves. Individuals are contagious from four days before the rash appears through four days after.
- Protocols for Care: Anyone showing potential symptoms should stay home and contact a healthcare provider immediately. Patients needing in-person emergency or urgent care must call ahead before arriving so facilities can implement safety precautions.
- Vaccination & Risk: While overall public risk remains low—especially for those fully vaccinated—unvaccinated individuals, infants, pregnant individuals, and immunocompromised people face the highest risk. The Seneca County Health Department is accessible by calling 315-539-1920.
