Gastrointestinal (GI) illness is caused by a variety of different disease-causing germs that can be acquired by consuming contaminated food or beverages, contact with contaminated recreational water, infected animals or their environments, or infected people. These germs can cause a variety of symptoms, such as diarrhea, nausea, vomiting, abdominal pain, fever, body aches, headaches and sometimes rash.  The Communicable Disease staff monitor and investigate GI illnesses that are spread through food, water, person-to-person contact and contact with infected animals.
