SULLIVAN COUNTY – With a rising number of reported cases of measles in neighboring Pennsylvania, the Sullivan County Department of Public Health is closely and actively monitoring the spread of this contagious disease.

“Our Epidemiology and Disease Surveillance team maintains ongoing surveillance and is in regular communication with the NYS Department of Health regarding emerging risks, guidance, and any activity that may impact Sullivan County,” says Public Health Director Dr. Jessie Moore. “Our clinical and outreach teams also monitor local measles-mumps-rubella (MMR) vaccine coverage and maintain vaccination access.”

According to the Pennsylvania Department of Health, as of Wednesday 594 measles cases have been confirmed across 37 counties in Pennsylvania so far in 2026.

Measles is a highly contagious virus that can cause serious short- and long-term health problems including pneumonia and brain swelling, with nearly 20 percent of people who contract measles being hospitalized.

Measles spreads when a person who is infected breathes, coughs, or sneezes. The virus remains infectious in the air and on surfaces for up to two hours after the person with the infection leaves the area.

Measles is not just a concern for children. Adults who are unsure of their immunity status should speak with their healthcare provider about whether immunity testing (titers) or MMR vaccination is appropriate.

Should a suspected case or exposure occur in Sullivan County, Public Health stands ready to immediately investigate, conduct contact tracing, coordinate testing, provide treatment and vaccinations, and notify the community.

“Public health emergency preparedness is intentionally integrated across our programs rather than operating as a stand-alone function,” adds Moore. “This allows epidemiology, nursing, clinical services, outreach, communications, and leadership to respond collectively and immediately based on the needs of an event, with continued coordination and guidance from the NYS Department of Health.”
