Pinworms are an intestinal parasite that is common in both adults and children. They can cause itching and discomfort around the anal area, leading to sleep disturbances and irritability. Pinworms are known by several synonyms, including threadworms, seatworms, and Enterobius vermicularis. Other lesser-known terms to refer to these parasites include rectal worms, anal worms, and helminths. Despite the different names used, the symptoms and treatment for pinworms remain the same across the board. Treatment often involves medication that helps to kill the worms and prevent re-infestation. Importantly, good hygiene practices such as proper handwashing can also help prevent the spread of pinworms.
