Bacterial Infection Hitting Northwest Iowa

SIOUX CITY, Iowa (AP) - Health officials say 95 cases of a contagious bacterial infection that causes diarrhea have been reported in northwest Iowa's Woodbury County.  The Siouxland District Health Department's deputy director Tyler Brock says the majority of those sick are children, but a number of adults have contracted shigellosis, too.  Most people who are infected with Shigella have frequent watery stools that could be bloody, as well as fever and stomach cramps, starting a day or two after exposure to the bacteria. Symptoms usually last several days.  Woodbury County recorded a single case of shigellosis last year.  But on Friday, 95 cases had been reported. About 20 of those had been diagnosed in early November.
