Enterobius vermicularis, commonly known as the pinworm, is a worm from a class of parasites known as nematodes, or simply roundworms. Pinworms are a common source of infection especially in children, where they have high chances of contracting a pinworm infection . More than 30% of children are infected with pinworms all around the world, but adults also can be infected with pinworms if they do not take the necessary precautions. Pinworms are usually half an inch in size, and they can be easily seen with naked eyes. The most common signs and symptoms of pinworms include peri-anal itching, nausea, and occasional abdominal pain. Also, presence of pinworms in the stool can lead to disturbed sleep due to the irritated anal region and the frequent itching and irritation in the anal area . This infection can be very troublesome and irritating in the long run. This is why you should treat this condition as soon as possible. Pinworm infection is caused by accidental ingestion or inhalation of the eggs by animals or humans, where the eggs are usually transferred via contaminated foods, drinks, or other infected utensils. Pinworm eggs are very small that they cannot be seen by naked eyes. Adult pinworms then continue to move in the body, and later they lay more eggs around the anal region of the infected person where the person then becomes infective to other people within hours. This cycle then continues on and on until the infection is cured, and the entire household of the infected person is disinfected. You need to talk with your doctor if you have pinworms before you start using some of the home remedies mentioned below.
