A restaurant worker at Crescent City Tavern in Dalton has tested positive for hepatitis A, according to the North Georgia Health District.

Health officials say the employee worked while infected from December 28 until January 31.

Anyone who dined at the restaurant is urged to contact their doctor to determine if a hepatitis A immunization is needed to prevent the disease.

Free vaccinations are also available at the Whitfield County Health Department.

Hepatitis A is a viral infection of the liver. Symptoms include loss of appetite, nausea, tiredness, fever, stomach pain, dark-colored urine and light-colored stools. Yellowing of the skin or eyes may also appear.

People can become ill up to 50 days after being exposed to the virus.

Hand-washing can prevent the spread of the virus.

The Whitfield County Health Department is located at 800 Professional Boulevard in Dalton.
