CHAPEL HILL — Orange County issued a health warning Friday night for anyone who has dined at Bud & Eb's Grill in Chapel Hill over the past few weeks.

Health officials say a restaurant worker has been diagnosed with Hepatitis A, and anyone who ate at the restaurant from Jan. 1 to Jan. 12 is at risk of infection as well.

Saturday, the Orange County Health Department waiting room was packed with Bud and Eb's customers. Many waited an hour or more to get a vaccination after learning that a cook was diagnosed with the virus.

Officials estimate that about 1,000 people may need a vaccine. Symptoms of Hepatitis include fever, nausea, vomiting, diarrhea, dark urine and jaundice.

Health officials say the restaurant is no longer hazardous, and the infected worker is at home.

Loyal patrons do not seem to mind getting a shot.

"I've been here a couple times between the period of January first through twelfth, and I intend to come back," says patron Cathryn Chappell. "I think it is a great place, and things like this just happen."
