In November 2025, The Asthma Center, which operates under Allergic Disease Associates, P.C., discovered suspicious activity on its computer systems. An investigation confirmed that an unauthorized actor accessed certain systems between October 28, 2025, and November 17, 2025, and may have downloaded files containing sensitive information. This incident was disclosed by August 2026. The Asthma Center provides specialized care for adults and children with allergies, asthma, sinus disorders, and other respiratory conditions in Philadelphia and southern New Jersey.
The review identified that names, dates of birth, health insurance member numbers, provider names, and medical information (including limited clinical, diagnosis, prescription, and treatment information) were potentially exposed. The exact number of affected individuals has not been publicly disclosed.
Further details, including official notifications to consumers, may emerge over time.
