BUFFALO, N.Y. (AP) — Health officials are warning diners at a western New York restaurant and residents of a nursing home that they may have been exposed to hepatitis A from an infected employee.

The Erie County Health Department issued the warning Tuesday to people who ate at the Al-E-Oops restaurant in Lancaster and the Brookdale Senior Living facility in Williamsville at the end of January.

The warning comes a day after a food service employee who worked at both locations tested positive for the contagious liver virus.

The county is offering immunizations to people who believe they've been exposed.

Symptoms of the virus can include fatigue, nausea and loss of appetite and joint pain.
