GRAND FORKS – The North Dakota Department of Health and Human Services (HHS) has confirmed one case of hepatitis A in a food worker in Grand Forks, possibly exposed following out-of-state travel. No additional cases have been identified at this time.

HHS determined that people who ate at the University of North Dakota Memorial Union Chick-fil-A at 3625 Campus Road in Grand Forks on various dates and times between Jan. 15-Feb. 7 may have been exposed to hepatitis A, which is a contagious liver infection.

Cases can happen in the U.S. in connection to eating contaminated food or drink, person-to-person contact or from other high-risk exposures. It can take about 15 to 50 days (average is one month) after being exposed to hepatitis A to develop symptoms.

The best way to prevent infection in exposed individuals is to receive a hepatitis A vaccine as soon as possible, according to HHS.
