The major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.
Parasites can get into the intestine and go through the mouth from uncooked or unwashed food, contaminated water, or hands, or by skin contact with larva infected soil. When the organisms are swallowed, they move into the intestine, where they can reproduce and cause. Children are particularly succeptible.
In some people, intestinal parasites do not cause any symptoms, or the symptoms may come and go. Common signs and complaints include coughing, cramping abdominal pain, bloating, flatulence and diarrhea. In more serious infections, diminished sex drive, skin-itching, fever, nausea, vomiting, or bloody stools may occur. Some parasites also cause low red blood count (anemia), and some travel from the lungs to the intestine, or from the intestine to the lungs and other parts of the body. Many other conditions can result in these symptoms, so laboratory tests are necessary to determine their cause.
In children, irritability and restlessness are commonly reported by parents.
