Health department officials say people that attended certain Catholic churches and took communion may be exposed to hepatitis A--which causes infection of the liver.
A press release names a September 27th service at Holy Spirit Church in Fargo, an October 2nd service at St. James Basilica in Jamestown, an October 6th service at Cathedral of St. Mary's in Fargo and an October 7th service at St. Paul's in Fargo.
Symptoms include fever, tiredness, loss of appetite, abdominal discomfort and jaundice.
It can take 15-50 days for symptoms to develop. They last up to two months.
Officials say to be tested only if you develop symptoms.
