Microscopic view of helminths, parasitic worms causing helminthiasis.

Helminthiasis refers to a medical condition caused by infection with helminths, commonly known as parasitic worms. These infections primarily affect the intestinal system but can also impact other bodily organs.

Etymology

The term "helminths" is derived from the Greek word meaning "worm."

Classification of Parasites

Helminth parasites that infect humans are traditionally classified into two categories:

• Heirlooms: Parasites inherited from ancestors, particularly in Africa.
• Souvenirs: Parasites acquired through contact with animals during human evolution, migrations, and agricultural practices.

Epidemiology

Helminthiasis is prevalent worldwide, with higher incidence rates in regions with poor sanitation and hygiene practices.

In developing countries, the most common infectious agents of humans are these helminthic infections. More than a quarter of the world's population, that means approximately 2 billion people are affected by the helminthic parasite, and it is one of the major burdens of developing countries, especially in children.

Symptoms and Diagnosis

Symptoms of helminthiasis vary depending on the type of worm and include:

• Abdominal pain
• Diarrhea
• Malnutrition and anemia
• In severe cases, organ damage

Diagnosis often involves stool tests, blood tests, and imaging for the detection of worms.

Treatment and Prevention

Treatment typically involves anthelmintic medications. Prevention strategies include:

• Improved sanitation and hygiene
• Adequate cooking of food
• Preventative public health measures in high-risk areas
