What is Ascariasis?
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.

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.

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.

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 .
