While assuring the public that there is no evidence of an outbreak, the Central District Health Department is alerting the public that an employee of the Cheesecake Factory on North Milwuakee Road in Boise, Idaho, was infected with the hepatitis A virus, but is no longer infectious.

CDHD is alerting patrons who may have dined at the restaurant between Dec. 13, 2011, and Jan. 22, 2012, that they may have been exposed to hepatitis A. If a person has had a hepatitits A vaccine or have had the illness in the past, the CDHD said they are protected from the infection.

"The risk to the public health is extremely low because the employee was not involved in food preparation," said a statement from CDHD. "Still, there is the possibility that patrons could have been exposed to hepatitis A."

The Cheesecake Factory has fully cooperated with the investigation into the situation. The employee is believed to have practiced good hand hygiene. The risk of exposure is considered very small, but not zero.
