The Allegheny County Health Department has confirmed a second case of measles in the county.

Pittsburgh, PA, October 9, 2026 — The Allegheny County Health Department (ACHD) announced on [Date of Announcement – Not Provided in Summary] that it has confirmed a second case of measles within the county. This development follows the recent confirmation of the county’s first measles case.
Health officials are urging residents to remain vigilant and informed about measles, a highly contagious viral illness. The ACHD is currently investigating the circumstances surrounding the second confirmed case to determine the source of infection and potential exposure timelines. Information regarding the identity of the affected individual, their vaccination status, or specific locations visited while potentially infectious was not immediately available.
Measles is spread through respiratory droplets when an infected person coughs or sneezes. Symptoms typically appear 7 to 14 days after exposure and can include a characteristic rash, fever, cough, runny nose, and red, watery eyes. The illness can lead to serious complications such as pneumonia, encephalitis (swelling of the brain), and death, particularly in young children and individuals with weakened immune systems.
The department’s Public Health nurses are working to identify and notify individuals who may have been exposed. Those identified will be provided with guidance on monitoring for symptoms and recommended actions. The ACHD emphasizes that vaccination is the most effective way to prevent measles. The measles, mumps, and rubella (MMR) vaccine provides strong protection against the disease.
Further details regarding public health advisories, potential exposure sites, and vaccination recommendations will be released by the Allegheny County Health Department as the investigation progresses. Residents seeking more information about measles or vaccination schedules are encouraged to consult the ACHD’s official resources or their healthcare providers.
