Shigella is a contagious infection typically spread by contaminated surfaces, food or water, or person to person. Those at increased risk include young children (especially those in daycare), people who are experiencing homelessness, travelers to locations with poor sanitation and men who have sex with men.

Typical symptoms of shigellosis include diarrhea (sometimes bloody), fever and stomach cramps. While most people will recover fully without antibiotic treatment, some individuals with poor immune systems can develop life-threatening disease and may need further treatment.
