SIOUX CITY, Iowa (AP) – The outbreak of a contagious bacterial infection that causes diarrhea has worsened in northwest Iowa’s Woodbury County.  Siouxland District Health Department Deputy Director Tyler Brock tells the Sioux City Journal that shigellosis had sickened 225 children and adults in the region as of Wednesday. That’s up from 95 cases in late November.   Woodbury County recorded a single case of shigellosis last year.

Most people who are infected 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.
