Roundworm infection: pinworms

Many people would be surprised at the amount of various microorganisms that live in our body. These microorganisms are bacteria, viruses, fungi, parasites and many other pathogens and they are really present in our body in great numbers. Not all of these microorganisms are harmful for the body; on the contrary, many of them assist in many body functions. All of these microorganisms live in our body in the excellent environment for their proliferation. However, the body’s immune system is so strong that it regulates their amounts.


Pinworms are the harmful microorganisms and they are intestinal parasites that cause pinworm infection, which is classified as the ringworm infection. Roundworms (including pinworms) use our digestive tract to live and multiply themselves laying eggs in the body until they grow into the adults, which means about 13 millimeters. These grownups then reach the anal area through the digestive tract and then again lay their eggs in the anal region.

Spreading of pinworms

Pinworms may be spread easily through several ways. In the majority of cases, the children are infected and they contract the infection when the pinworms or their eggs get under their fingers, which usually happens when they are scratching their bare anal region. The eggs of pinworms can also be spread when a child does not wash the hands after going to toilet and then touches some toy. Thus, the person who next takes that toy gets infected. The infected child may also spread the pinworms eggs not only to the toys but also everywhere in the house.

The pinworms eggs can survive even two weeks outside our body and we can inhale them when breathing or when we eat foods in which they are deposited. Since the spreading of the pinworms is very easy, it is important to prevent it by taking some precautionary measures, like frequent washing of hands, daily bathing and frequent changing and washing of cloths.

Symptoms of pinworm infection

In mild cases of pinworm infection, the infected people usually do not notice any symptom. Only when the infection is moderate or severe, the symptoms start to show themselves. Pinworm infections tend to cause uncomfortable itching around the anal region, while in cases of girls, it can lead to the occurrence of vaginal itching and irritation, which is known as vaginalitis. The people who contract this type of infection may often experience nervousness, irritability, exhaustion and sleeping disorders. Pain in the abdomen, nausea and the loss of body weight are also some of the warning signs of the pinworm infection.
