Ascariasis may be a roundworm infection of your intestines. It’s common throughout the planet in places wherever sanitation is poor. In these areas, individuals could also be carrying the parasite that causes the infection.

Ascariasis, hookworm and whipworm square measure parasitic worms. They’re referred to as soil-transmitted helminths (STH) as a result of the infection spreading through contaminated soil.

What is Ascariasis?

Ascaris, typically abbreviated as A., is the cluster of worms that cause infestation. The worm sounds like the common oligochaete. It’s about half a dozen to thirteen inches long and about as thick as a pencil. Up to a hundred worms might probably infect an individual.

A calculable 807 million–1.2 billion individuals within the world square measure infected with nematode worm (sometimes known as simply genus Ascaris or ascariasis). Ascaris, hookworm, and whipworm square measure parasitic worms referred to as soil-transmitted helminths (STH). Together, they account for a serious burden of parasitic sickness worldwide. Infestation is no longer common within the us.

Ascaris parasites board the internal organ. genus Ascaris eggs square measure passed within the body waste (poop) of infected individuals. If an infected person defecates outside (for example, close to bushes, during a garden, or during a field), or if the body waste of an infected person is employed as chemical, worm eggs square measure deposited on soil. The worm eggs will then grow into a kind of parasite which will infect others. Infestation is caused by ingesting those worm eggs. This will happen once hands or fingers that have contaminated dirt on them square measure place within the mouth, or by consuming vegetables or fruits that haven't been fastidiously raw, washed, or cooked.

People with infestation usually show no symptoms. If symptoms occur they will be light-weight. Symptoms embrace abdominal discomfort or pain. Serious infections will block the intestines and slow growth in kids. different symptoms like cough square measure thanks to migration of the worms through the body. infestation is treatable with medication prescribed by your care supplier.

Humans may also be infected by pig roundworm (Ascaris suum). nematode worm (human roundworm) and genus Ascaris suum (pig roundworm) square measure arduous to inform apart. It's unknown what number of individuals worldwide square measure infected with genus Ascaris suum.

medical terms

  • Ascariasis is a parasitic infection caused by roundworms from the Ascaris genus. It is the most common type of helminthic, or parasitic worm, infection in humans and is estimated to affect around 1.2 billion people worldwide. Ascariasis is spread by ingesting contaminated food or water, which can contain tiny eggs that hatch into larvae in the human digestive system.

  • Ascariasis happens most frequently in youngsters in tropical and subtropical regions of the globe — particularly in areas with poor sanitation and hygiene. 

  • Ascariasis is caused by the roundworm Ascaris lumbricoides and is one of the top 10 parasitic infections in humans The worms live in the lower intestine where they consume blood and other nutrients causing abdominal pain and diarrhea The disease can lead to malnutrition low weight gain in children stunted growth vitamin deficiencies and anemia It has been estimated that there are 1.4 billion people with ascariasis around the world Most cases occur in developing countries where access to clean water or appropriate sanitation facilities or health services is limited or non-existent.

  • Ascariasis is a common intestinal worm infection The worms live in the small intestine and females live for up to 15 years in humans Ascariasis mostly affects preschool children who acquire the infection when they swallow soil contaminated with dog or cat feces or through hand-to-mouth contact while playing with pets People can also contract this condition by eating uncooked vegetables grown in contaminated soil or drinking water that has not been adequately purified of fecal matter In tropical countries where ascariasis is prevalent people are at risk of re-infection if they do not wash their hands after using the bathroom and before preparing food.

Children typically become infected after they place their hands in their mouths once enjoying contaminated soil, in step with the World Health Organization. infestation may also be passed directly from person to person.

Ascariasis does not unfold directly from person to person. Instead, an individual needs to get contact with soil mixed with human or pig feces that contain infestation eggs or infected water. In some developing countries, human feces are used for plant food, or poor healthful facilities permit excretory products to combine with soil in yards, ditches and fields. folks may also grasp from feeding raw pig or liver that's infected.

Small children typically play in dirt, and infection will occur if they place their dirty fingers in their mouths. Unwashed fruits or vegetables fully grown in contaminated soil can also transmit the infestation eggs.

Life cycle of a worm

  • Ingestion. The tiny (microscopic) infestation eggs cannot become infective while not coming back into contact with soil. individuals will accidentally ingest (swallow) contaminated soil through meager contact or by ingestion raw fruits or vegetables that are big in contaminated soil. 

  • Migration. Larvae hatch from the eggs in your intestine and so undergo the enteric wall to jaunt the center and lungs via the blood or vascular system.

The roundworm is found worldwide, however it’s additionally often found in tropical and climatic zone regions, as well as geographical area and geographic area. It’s conjointly common in areas wherever sanitation is poor.

Risk factors for ascariasis include:

  • Age. Most people who have ascariasis are 10 years old or younger. Children in this age group may be at higher risk because they're more likely to play in dirt.

  • Warm climate. In the u. s., infestation is additional common within the Southeast. However, it's additionally frequent in developing countries with heat temperatures year-round . 

  • Poor sanitation. Ascariasis is widespread in developing countries where human feces are allowed to mix with local soil.

CT scans mix X-ray pictures taken from several angles. MRI uses radio waves and a powerful force field. 

Treatment Ascariasis

In developing countries, teams at higher risk for soil-transmitted parasitic worm infections (hookworm, Ascaris, and whipworm) are usually treated while not having a previous stool examination. Treatment during this method is termed preventive treatment (or “preventive chemotherapy”). The unsound teams are known by the globe Health Organization area unit educational institution and school-age kids, ladies of childbearing age (including pregnant ladies within the ordinal and third trimesters and wet women) and adults in occupations wherever there's a high risk of significant infections. School-age kids are usually treated through school-health programs and educational institutions for kids and pregnant ladies at visits to health clinics.

Typically, solely infections that cause symptoms have to be compelled to be treated. In some cases, infestation can resolve on its own.


Anti-parasite medications are the first line of treatment against ascariasis. The most common are:

  • Albendazole (Albenza)

  • Ivermectin (Stromectol)

  • Mebendazole

These medications, taken for one to a few days, kill the adult worms. aspect effects embody gentle abdominal pain or looseness of the bowels.

Pregnant girls could take pyrantel pamoate.

The roundworms can grow up to a foot long and reside in the small intestine, where they cause damage to the lining and lead to abdominal pain, nausea, and diarrhea. Severe infections can result in blockages in the intestines and even serious complications such as obstruction of the bile duct or pancreatic duct.

  2. Ascariasis is a disease caused by a type of roundworm that affects the intestines of humans. It is also known as “small intestinal roundworm infection” and is one of the most common parasitic infections in the world, affecting about 1 billion people globally. The small intestine is the main organ affected by ascariasis. The roundworm larvae enter the body through contaminated food or water and then migrate to the small intestine where they mature into adults.

  3. The best way to treat ascariasis is to take medications that kill the parasites. A doctor may prescribe albendazole or mebendazole as treatment for ascariasis in humans.
