BISMARCK, N.D. – Thirteen cases of the intestinal disease shigellosis have been confirmed in Rollette County this month, state health officials said.
State epidemiologist Kirby Kruger said 12 of the cases involve children, and six people have been hospitalized.
Kruger said five additional cases are pending laboratory confirmation.
Shigellosis is caused by shigella bacteria, which are spread through undercooked or contaminated food and poor hygiene. The illness can cause bloody diarrhea, fever, vomiting and stomach cramps. Typical treatment is fluids and antibiotics.

The Health Department said a common source for the infections has not been found.
Kruger said some people sickened by the disease reported swimming at Lake Upsilon in Rolette County. Water samples from the lake this month tested negative for sewage contamination, he said.
