A00-A09: Intestinal infectious diseases
A07: Other protozoal intestinal diseases
The category of "Other protozoal intestinal diseases" encompasses illnesses caused by tiny, one-celled organisms called protozoa which can infect the digestive systems. Such diseases can occur when these organisms are ingested, often through contaminated food, water, or even contact with fecal matter. Once inside the body, these parasites may cause a range of symptoms like diarrhea, abdominal pain, cramping, and nausea. For some people, symptoms may remain mild and self-limited while others can experience severe symptoms, including dehydration. The disease progression differs from one person to another, and depends largely on the type of organism causing the infection, along with the individual's overall health status. Multiple body systems can be affected, but the digestive system is usually the primary target.
