Whipworm Infection [Trichiniasis]

Whipworm Infection [Trichiniasis]

A whipworm infection, also known as trichuriasis, is an infection of the large intestine caused by a parasite called Trichuris trichiura. This parasite is commonly known as a “whipworm” because it resembles a whip.

A whipworm infection can develop after ingesting water or dirt contaminated with feces containing whipworm parasites. Anyone who has come into contact with contaminated feces can also contract a whipworm infection. The infection most often occurs in children. It is also more common in people who live in regions with hot, humid climates and in areas with poor hygiene and sanitation.

What Are the Symptoms of a Whipworm Infection?

A whipworm infection can cause a variety of symptoms, ranging from mild to severe. They may include the following:

  • bloody diarrhea
  • painful or frequent defecation
  • abdominal pain
  • nausea
  • vomiting
  • headaches
  • sudden and unexpected weight loss

Poor hygiene is associated with T trichiura transmission, and children are especially vulnerable because of their high exposure risk. This is especially true in developing countries, where poor sanitary conditions correlate with heavy disease burden and infections.

How does trichuriasis spread?

Trichuriasis is associated with poor hygiene. Children are particularly vulnerable to infection, particularly in developing countries. It is thought that partial immunity to whipworms develops with age.

What Causes a Whipworm Infection?

A whipworm infection is caused by a parasite called Trichuris trichiura. This parasite is also known as a “whipworm” because it is shaped like a whip. It has a thick section on one end that resembles the whip handle, and a narrow section on the other end that looks like the whip.

People typically get whipworm infections after consuming dirt or water contaminated with feces containing whipworm parasites or their eggs. Whipworm eggs can get into the soil when contaminated feces are used in fertilizers or when an infected person or animal defecates outside.

How is trichuriasis confirmed?

Trichuriasis is diagnosed by looking under the microscope for whipworm eggs in the stool. Sometimes, the adult worms can be seen on proctoscopy or colonoscopy. A female whipworm normally produces up to 25,000 eggs per day which is huge.

How is trichuriasis treated?

Treatment of trichuriasis is with anthelminthic medication such as mebendazole or albendazole.

Prevention of infection is equally important. Children and adults should wash their hands before handling food, and wash, peel, and cook food fully before eating. Improving sanitation is the best way to eradicate trichuriasis.

What Are the Risk Factors for a Whipworm Infection?

A whipworm infection can occur in anyone. However, people may be more likely to contract a whipworm infection if they:

  • live in a region with a hot, humid climate
  • live in an area with poor sanitation and hygiene practices
  • work in an industry where they come into contact with soil that contains manure
  • eat raw vegetables that are grown in soil fertilized with manure

Children also have a higher risk of getting a whipworm infection. They often play outdoors and might not wash their hands thoroughly before eating.
