QUEEN CREEK -- Health officials say Hepatitis A has been discovered in a food handler working at a Subway restaurant in Queen Creek.

Pinal County health officials say they're investigating. They tell the Tribune that anyone who ate at the restaurant between Dec. 10 and dec. 23 may have been exposed to the virus.

Hepatitis A can lead to liver disease and should be treated immediately.

This latest case comes on the heels of a report that food handlers who worked at two Guadalupe restaurants had the virus and customers may have been exposed last month.

The virus can spread after an infected person fails to thoroughly wash their hands after using the restroom.
