Health officials say people who ate at a doughnut shop in Wilkesboro earlier this month may have been exposed to hepatitis A.

The Wilkes County Health Department said an employee at Dixie Donuts was diagnosed with the virus Sunday.

Authorities say people at the most risk would have eaten at the business in the morning on May 8 or May 9, or in the afternoon and evening on May 10 or May 12.

Hepatitis A attacks the liver and is contracted through food, drink or close contact with an infected person. A vaccine can reduce the risk of contracting the disease if taken within two weeks of exposure. Otherwise, doctors often let hepatitis A run its course. Symptoms like nausea, diarrhea and yellowing of the skin can last for weeks.
