Enterobiasis is the most common type of worm infestations. Pinworm (Enterobius) is thin white worm, living as a parasite in the gut and causing Enterobiasis.
The main symptom of enterobiasis
Itching in the anal area (usually in the evening, at night or early in the morning) is one of the most common symptoms. People having small quantity of pinworms may have no obvious signs of the disease.But more often certain signs of the disease are usually observed. In mild enterobiasis the patient has mild itching in the area around the anus at bedtime. The itching lasts 1-3 days and then spontaneously disappears, but after 2-3 weeks it often reappears. This periodicity in the occurrence of itching is associated with the change of pinworm generations, which occurs as a result of re-infection as female worms postpone eggs and die.
The symptoms of moderate and severe enterobiasis
If there is large number of pinworms in the patient’s intestine and in the cases of massive re-infection – the itching becomes constant and very painful. Combing of anus area leads to secondary bacterial infection of the skin and the appearance of dermatitis. All this aggravates the disease. In some cases, the main sign of the disease are intestinal disorders, which are characterized by frequent mushy stools, sometimes with mucus, pain in the perineum.
Although the most characteristic feature of enterobiasis is itching in the anal area, it is necessary to remember that itching is observed in a number of other diseases – proctitis, hemorrhoids, bowel cancer, chlamydia, genital trichomoniasis, liver disease and kidney disease, candidiasis, diabetes, atopic dermatitis, etc. Therefore, to clearly define the diagnosis of enterobiasis, pinworm eggs or worms should be detected.
Pinworms postpone eggs mainly in the area around the anus, very rare in the gut. Therefore, is usually not possible to find them in the stool. Much easier to find pinworm eggs, examining scrapings from the skin, surrounding the anus under a microscope. Pinworm eggs are often detected under the fingernails.
