Roundworms, also known as nematodes, are parasitic worms that live in the intestines or other areas of the human body, according to the University of Maryland Medical Center. These parasites typically enter the body through the mouth or the skin. They are most common in tropical climates, although children in cooler areas may experience roundworm infections as well. Because there are several types of roundworms, your child may experience a variety of symptoms that can point to a roundworm infection.
Strongyloidiasis
One type of roundworm, Strongyloides stercoralis, is a parasite that causes a condition called strongyloidiasis, according to the Cleveland Clinic website. Although many cases of strongyloidiasis are mild and do not produce symptoms, moderate cases of this condition are characterized by vomiting, a burning sensation in the abdomen, nausea, constipation and diarrhea.
Trichinosis
Trichinosis is an infection caused by the Trichinella spiralis roundworm, which is found in pork and food waste. Children who eat pork are particularly susceptible to this infection. According to the University of Maryland Medical Center, children with trichinosis can exhibit symptoms such as pain in the abdomen, pink eye, increased sensitivity to light, acute fever and diarrhea.
Hookworm Disease
Hookworm disease is one of the most common types of roundworm infections, according to the Cleveland Clinic website. These roundworms live in fecal matter and infected soil, and can be contracted by touching contaminated soil. Your child may experience diarrhea when infected with hookworms, especially if he has never had a hookworm infection before. Other symptoms include abdominal cramps and nausea.
Ascariasis
Ascariasis is typically caused by ingestion of food grown in soil contaminated by Ascaris lumbricoides larvae or eggs. This type of infection is more common than any other type of roundworm infection, according to the University of Maryland Medical Center. Symptoms of ascariasis include breathing difficulties, fatigue, pain in the abdomen, coughing and nausea.
