Definition

Ascariasis is a human disease. It is caused by the parasitic roundworm name as Ascaris lumbricoides.
Perhaps as many as one quarter of the world’s people are infected, and
ascariasis is particularly prevalent in tropical regions and in areas
of poor hygiene. Other species of the genus Ascaris are parasitic and can cause disease in domestic animals.

They
may however be accompanied by inflammation, fever, and diarrhea, and
serious problems may develop if the worms migrate to other parts of the
body.

Causes

Ascariasis is the most common intestinal worm
infection. It is found in association with poor personal hygiene, poor
sanitation. In many developing countries human feces are used for
fertilizer, or poor sanitary facilities allow human waste to mix with
local soil in yards, ditches and fields. The eggs can survive in soil
for years to reinfect members of the community. The eggs infect their
hosts when humans eat the contaminated vegetables and fruit grown in
that soil.Once in the stomach, immature worms hatch from the eggs. The
larvae are carried through the lungs and then to the throat where they
are swallowed. Once swallowed, they reach the intestines and develop
into adult worms. During movement through the lungs the larvae may
produce an uncommon form of pneumonia called eosinophilic pneumonia.

It
is estimated that 1 billion people are infected worldwide. Ascariasis
occurs in all ages, though children seem to be affected more severely
than adults.

Symptoms

Although no symptoms may occur, the
greater the number of worms involved in the infestation, the more
severe a child’s symptoms are likely to be. Children are more likely
than adults to develop gastrointestinal symptoms because they have
smaller intestines and are at greater risk of developing intestinal
obstruction. The following symptoms may be seen with mild infestation:

• worms in stool
• coughing up worms
• loss of appetite
• fever
• wheezing
• vomiting
• shortness of breath
• abdominal distention
• severe stomach or abdominal pain
• intestinal blockage
• biliary tract blockage

More
than 796 Ascaris lumbricoides worms weighing 550 g [19 ounces] were
recovered at autopsy from a 2-year-old South African girl. The worms
had caused torsion and gangrene of the ileum, which was interpreted as
the cause of death.

Treatment

Anti-parasite
(antihelminthic) medications are the first line of treatment against
ascariasis. The most common are mebendazole (Vermox), albendazole
(Albenza) and pyrantel. These medications work by killing the adult
worms as well as the larvae and eggs to prevent reinfection. You may
have mild gastrointestinal side effects during the course of treatment,
and you may need to take multiple doses to get rid of the infestation
completely.

Some recent studies exist in the medical literature
suggesting that sun-dried papaya seeds may reduce infections by a large
factor. The adult dosage is one tablespoon of the seed powder in a
glass of sugar water once a week for two weeks.
