Buffalo Wild Wings confirms that a Middletown employee is suffering from hepatitis A

WHAT HEPATITIS HAS:Here is what you need to know

"We take food safety very seriously and immediately shut down the restaurant and put in place a thorough cleaning process," spokesperson Alison Glenn said in an email. "We worked closely with the Delaware Public Health Division and the restaurant reopened to the public yesterday."

Hepatitis A is a viral infection that affects the liver. It spreads when a person unknowingly ingests the virus from objects, food or drink contaminated with small undetected amounts of stool from an infected person.

The virus can spread in a restaurant when an infected person does not wash his / her hands enough after using the toilet, preparing food or sharing utensils with others while eating.

Symptoms may include loss of appetite, nausea, tiredness, fever, stomach pain, yellowing of the skin of the eyes, brown urine and pale stools. They usually appear 15 to 50 days after exposure.

If someone develops these symptoms, he must stay at home and contact his doctor, said public health officials.
