A00-A09: Intestinal infectious diseases

Intestinal infectious diseases refer to a variety of infections that occur within the digestive tract, more specifically, the intestines. These illnesses can have various causes, typically arising from harmful bacteria, viruses, or parasites entering the body. Frequently, transmission happens due to ingesting contaminated food or water, close contact with an infected person, or exposure via unwashed hands, utensils or bathroom facilities. Classic symptoms shared among these infections include diarrhea, abdominal pain, cramps, bloating, and occasionally fever, nausea, or vomiting. Severity and duration of the disease depend on the specific causative agent, a person's overall health status, and the quickness of diagnosis. These conditions primarily compromise the digestive system, yet untreated or severe cases might lead to complications impacting other body systems. Due to the diverse array of microbes that can cause these diseases, the type of intestinal infectious disease is usually determined through medical tests examining stool samples.
