Parasitic Worm Infection
Parasitic worm infections occur when helminths, roundworms, hookworms, tapeworms, or pinworms, take up residence in the gut or other tissues.
Key takeaways
- Symptoms range from none to abdominal problems, itching, anaemia or organ-specific illness, depending on the worm and where it is located.
- Exposure history, stool tests, blood tests or imaging may be needed because treatment differs between intestinal and tissue infections.
- Albendazole treats selected helminths, not every worm infection, and pregnancy or liver disease can alter the plan.

How worm infections spread and who they affect
Transmission and organ involvement differ by worm species. Heavy or longstanding intestinal infection can contribute to anaemia or poor nutrition, particularly in children. Albendazole treats some—but not all—helminths, so organism, exposure history, pregnancy and possible tissue involvement affect medicine choice and follow-up.
Why the exact diagnosis matters
Pinworm, hookworm, roundworm, tapeworm and tissue-invasive infections require different medicines and follow-up. Treating an assumed intestinal infection can miss disease involving the liver, lungs, brain or other tissues. Household measures or treatment of close contacts are useful for some infections but not universally required.
When to seek urgent care
Seek urgent care for severe abdominal pain or swelling, repeated vomiting, blood in stool, fainting, confusion, seizures, breathing difficulty or severe dehydration. A child with marked weakness, poor growth or a heavy suspected infection needs prompt assessment.
