B81

B81 is a code used in the International Classification of Diseases (ICD) to denote a specific type of parasitic disease. The full code, B81.0, refers to Enterobiasis, a type of parasitic infection caused by the Enterobius vermicularis worm, commonly known as the pinworm.

Overview

Enterobiasis is a common parasitic infection, particularly among children. It is caused by the Enterobius vermicularis worm, which is ingested and then matures in the host's intestines. The female worms lay eggs around the anus, causing intense itching. This often leads to re-infection as the eggs are transferred back to the mouth via the fingers.

Symptoms

The primary symptom of enterobiasis is pruritus ani, or intense itching around the anus. Other symptoms can include discomfort, irritability, and insomnia due to the itching. In severe cases, the infection can lead to complications such as appendicitis or peritonitis.

Diagnosis

Diagnosis of enterobiasis is typically made through the identification of eggs or adult worms. This is often done through the "tape test", where a piece of clear tape is applied to the anal area upon waking, then examined under a microscope for the presence of eggs.

Treatment

Treatment for enterobiasis typically involves a course of anti-parasitic medication, such as mebendazole or albendazole. It is often recommended that all members of a household receive treatment, due to the ease with which the infection can spread.

Prevention

Prevention of enterobiasis involves good hygiene practices, such as regular hand washing, particularly before meals and after using the toilet. It is also important to clean and vacuum living areas regularly to remove any eggs.
