👉 Pinworm is a type of worm that lives in the skin and can cause infections, particularly on the nails. They are commonly found in children's toenails and can be transmitted through direct contact with infected fingernail crevices or by sharing toys with someone who has pinworms. Pinworms may also infect other parts of the body such as the mouth, anus, and vagina. Treatment for pinworms usually involves oral antiseptic rinses (such as chlorhexidine)
