Ascariasis: is one of the commonest infections of the small intestine. Caused by a nematode called Ascaris lumbricoides ( round worm) 

Mode of Transmission of Ascariasis

• Common ways of acquiring ascariasis include failure to adhere to hygienic practices such as washing hands before food preparation and proper storage of food.
• Therefore the disease is related to poor sanitation and hygiene.
• Infection is acquired from ingestion of food contaminated with mature eggs
• The usual vehicles are fruits and other raw food
• Children are more frequently infected and have higher worm burden than adults because they like putting contaminated objects into their mouths
• Heavy infection in children can contribute to under-nutrition.
• Adults have much lighter infections, although re-infection can occur throughout life.

Signs and Symptoms of Ascariasis

• Cough
• Abdominal discomfort, restlessness and insomnia (sleeplessness)
• Eosinophilia due to allergic reaction
• Intestinal obstruction
