Understanding Ascariasis: Causes, Symptoms, Diagnosis, and Treatment

Ascariasis, also known as roundworm infection, is a condition caused by roundworms that live in the small intestine of humans. This article discusses the causes, symptoms, diagnosis, and treatment of ascariasis.


  • Ascariasis is caused by roundworms, which can grow up to about 25-40 cm in length and live for up to one year.
  • The female worm lays up to 200,000 eggs, which are passed into the soil with feces and mature there.
  • Contact with contaminated soil, consumption of unwashed fruits and vegetables, and poor hand hygiene are contributing factors in transmission.

Infection Process:

  • Eggs grow in the soil, mature, and are then swallowed by humans.
  • Larvae migrate through the bloodstream to the lungs and are then swallowed again, reaching the small intestine where they develop into mature roundworms.
  • This process takes about 14-15 days.


  • Ascariasis symptoms can be divided into two stages: migratory and intestinal.
  • Migratory stage: Symptoms include skin rash, itching, coughing, and chest pain.
  • Intestinal stage: Symptoms include nausea, stomach pain, loss of appetite, weight loss, and diarrhea.


  • Stool examination for worm eggs.
  • General blood analysis.


  • In the migratory stage, Dimedrol, calcium chloride, and calcium gluconate are used.
  • Drug treatment includes anthelmintics such as albendazole, mebendazole, pyrantel pamoate, nitazoxanide, and others.
  • Prevention includes personal hygiene practices, mass screening, and careful sewage and waste treatment.

Understanding the causes, symptoms, diagnosis, and treatment of ascariasis is important for effectively managing this common medical condition. By following preventive measures and consulting a doctor if infection is suspected, the risk of infection can be reduced, and overall health can be improved.
