Ascaris

Ascaris is a genus of parasitic nematode worms which are among the most common human parasites. Ascaris lumbricoides, the most common species, is responsible for the most prevalent intestinal worm infection in humans, known as ascariasis. Ascaris lumbricoides is distributed worldwide, mainly in tropical and subtropical regions with poor sanitation. Infection may lead to a range of symptoms and health effects, including abdominal discomfort, malnourishment, and impaired growth and development. Ascariasis is treatable with anthelmintic drugs, but mass drug administration is necessary to reduce transmission and prevent re-infection. Thus, improved sanitation and hygiene are important strategies for reducing the burden of Ascaris transmission.
