Ascaris lumbricoides, or “roundworm”

Roundworm is most prevalent in regions with hot, humid climates and inadequate sanitation. The parasite primarily affects children ages 1-14. The worms live in the intestines, and the eggs are passed through the feces of an infected person and contaminate the soil. They are transmitted by ingestion of the eggs on unwashed fruits and vegetables, utensils, or dirty hands that have been exposed to feces-contaminated soil. The health effects range from mild abdominal discomfort to severe infections that can lead to bowel obstruction, rupture, and death. Malnutrition can develop among those infected with intestinal worms. Children with these infections may also have mental and physical growth impairments. Roundworm infections are preventable and treatable with prescribed medication.
