Hello, It seems you have pinworm infection which can easily be cured. Since if proper measures are not undertaken, this infection is likely to recur. The following treatment and prevention recommended for pinworm infection. -A single oral dose of Mebendazole or Albendazole, repeated in two weeks, is effective in the eradication of pinworms. -Do not use your toothpaste to get rid of the worms as it is not effective in the total eradication of the worms. -You may apply carbolated petrolatum or other antipruritic creams or ointments to the perianal region may relieve itching. The infection can be prevented by: 1. All family members or classmates must be treated simultaneously. 2. Personal and group hygiene must be improved: You must wash your hands before eating, and refrain from activities such as scratching the perianal area), finger-sucking, nail-biting, and your nails should be trimmed. 3. To reduce your risk of getting or spreading infection, wash your hands thoroughly after having a bowel movement or changing a diaper and before eating. 4. Daily morning bathing and daily changing of underwear help remove a large proportion of eggs. Showering is preferred to avoid possible contamination of bathwater. 5. Careful handling and frequent changing of underclothing, nightclothes, towels, and bedding can help reduce infection, reinfection, and environmental contamination with pinworm eggs. These items should be laundered in hot water, especially after each treatment of the infected person, and after each usage of washcloths until the infection is cleared.
