Ascaris lumbricoides is a species of Ascaris that lives in the human intestine and adults may grow to 12 in. long. Eggs are passed with the feces and require at least 2 weeks’ incubation in the soil before they become infective
Ascaris lumbricoides, an intestinal roundworm, is one of the most common helminthic human infections worldwide.

- It is estimated that more than 1.4 billion people are infected with A. lumbricoides, representing 25 percent of the world population.
- The highest prevalence of ascariasis occurs in tropical countries where warm, wet climates provide environmental conditions that favor year-round transmission of infection.
- This contrasts to the situation in dry areas where transmission is seasonal, occurring predominantly during the rainy months
ASCARIS LUMBRICOIDES is found worldwide.
- Transmission is enhanced by the fact that individuals can be asymptomatically infected and can continue to shed eggs for years, yet prior infection does not confer protective immunityHow to Manage Hay Fever at Home. Read more ... »

- Route of infection is oral.
- The gastrointestinal location of worms is small intestine.
- In a 1- to 2-year life span, the female is capable of producing 200,000 eggs per day.

- Transmission occurs mainly via ingestion of water or food (raw vegetables or fruit in particular) contaminated with A. lumbricoides eggs and occasionally via inhalation of contaminated dust.
- When infections with only female worms occurs, infertile eggs that do not develop into the infectious stage are produced.
- With male-only worm infections, no eggs are formed.
- · 65 – 70 days and may survive for one year.
- Larvae usually reach the lungs by four days after ingestion of eggs.

- The mainstays of treatment are the benzimidazoles mebendazole and albendazole.
- Mebendazole (100 mg BID for 3 days or 500 mg as a single dose) is an alternative
- A single dose of albendazole (400 mg) is effective in almost 100 percent of cases, although reinfection commonly occurs,
- a single does of either 400 mg albendazole or 200 mcg/kg ivermectin showed similar cure rates (70 percent versus 78 percent) and egg reduction rates (93 percent versus 94 percent) for both therapies,
- However, they should not be given during pregnancy because of possible teratogenic effects; pyrantel pamoate should be used in pregnancy.
