Etymologies

ascar(id) + -iasis.
(American Heritage® Dictionary of the English Language, Fourth Edition)

Examples

  • Infections of this intestinal roundworm, called ascariasis, are extremely common in rural communities around the world and affect as many as 1.5 billion people, almost one-quarter of the world's population.

    undefined

  • This plant is widely used in medicine for treating ascariasis and as a bactericidal agent; it is also used in perfume industry.

  • They would learn that a significant number of other crippling and killing diseases, including African river blindness, schistosomiasis, trauchoma, lymphatic filariasis, hookworm, ascariasis, and trichuriasis, could be brought under control for well under $2 per American citizen per year, and perhaps just $1 per American citizen!

    How Aid Can Work

  • Excreta fertilized crops are, therefore, potential transmitters of A. Lumbricoides eggs where ascariasis is endemic.

    Chapter 6

  • The World Health Organisation has identified ascariasis as a neglected disease in urgent need of better research and control.

  • Ascaris suum is closely related to Ascaris lumbricoides which causes ascariasis in humans.

    Ascariasis is the most common helminthic infection, with an estimated worldwide prevalence of 25% (>1.25 billion people). Usually asymptomatic, infections are most prevalent in tropical and developing countries, where they are perpetuated by contamination of soil by human feces or use of untreated feces as fertilizer. Symptomatic disease may be manifested by growth retardation, pneumonitis, intestinal obstruction, or hepatobiliary and pancreatic injury. In developing countries, ascariasis may exist as a zoonotic infection associated with exposure to pigs or pig manure.

    Intestinal obstruction in children is the most commonly attributed fatal complication, resulting in 8000-100,000 deaths per year, according to the World Health Organization. Besides direct obstruction of the bowel lumen, toxins released by live or degenerating worms may result in bowel inflammation, ischemia, and fibrosis.

    History:
    Symptoms include cough, dyspnea, asthma, and chest pain (during the initial lung migration). This may be seasonal in some countries, such as Saudi Arabia.
    Abdominal pain, distension, colic, nausea, anorexia, and intermittent diarrhea may be manifestations of partial or complete intestinal obstruction by adult worms.
    Jaundice, nausea, vomiting, fever, and severe or radiating abdominal pain may suggest cholangitis, pancreatitis, or appendicitis.

    Physical:
    Rales, wheezes, and tachypnea may be present during pulmonary migration.
    Abdominal distension is nonspecific but is often observed in children with worms.
    Abdominal tenderness, especially in the right upper quadrant, hypogastrium, or right lower quadrant, may suggest complications of ascariasis.
