The Erie County Health Department is investigating a possible case of measles at Williamsville South High School. Exposure may have occurred on Friday.
The district sent out an alert notifying the "parents and guardians of South students, and employees about the investigation" as a precautionary measure.
The Health Department says measles is a highly contagious respiratory disease, first causing a fever, then perhaps a cough, runny nose and watery eyes, followed by the appearance of a rash.
Last week, the Health Department confirmed a case of measles in a person who recently arrived from an unspecified Eastern European country. The Williamsville Central District also announced a confirmed case of tuberculosis in an employee that potentially affected nearly 200 students in three different schools.
