Nassau County health officials have confirmed a second measles case this year, and this time the potential exposure site wasn't a doctor's office or a school — it was a restaurant table in Roslyn Heights. Officials say an infected New York City resident dined at 388 Italian Restaurant on Willis Avenue on May 3, and anyone who was there between 7:15 p.m. and 10:30 p.m. that night may have been exposed to the virus.
The news comes after the county's first confirmed case of the year, which involved an unidentified, unvaccinated child under the age of 5, according to longisland.com. The Nassau County Department of Health said it was closely investigating the second case, including any potential exposures tied to the restaurant visit.
Measles is a highly contagious illness. Complications can include pneumonia and encephalitis, and in the most serious cases the disease can lead to hospitalization or death.
Measles Cases Across New York
So far in 2026, there have been 10 confirmed cases of measles across New York state, per the same report.
Measles is highly contagious, and a single case can prompt a public-health response.
Nassau's Previous Case
How unusual is a measles case in Nassau County? A report citing county officials put the county's last confirmed case in March 2025. Health officials have treated both of this year's cases as rare enough to warrant public alerts.
The county's exposure notice for the restaurant visit, issued through its Nassau County Department of Health alert system, laid out the specific window during which anyone dining at the Roslyn Heights restaurant could have come into contact with the virus. The earlier case, also confirmed by the county, involved a laboratory-confirmed infection in an unvaccinated child under 5.
What Residents Are Being Told to Do
Officials have not publicly identified either patient, consistent with standard privacy practices in these investigations. What they have emphasized is the importance of vaccination status for anyone who may have been near either case. Measles spreads easily through the air and can linger in a space even after an infected person has left, which is why health departments move quickly to publicize exposure windows down to the minute.
For now, the Nassau County Department of Health says its investigation into the second case remains active, with officials continuing to examine potential exposures connected to the Roslyn Heights visit. The county's notice identified the restaurant and the exposure window for anyone who may have been there.
