What is the most effective way to prevent Enterobiasis (pinworm) infection?

• A. Hand washing with warm water and soap is most successful way to prevent infection
• B. Prevent spread of infection with daily morning showers to remove large amount of eggs on skin
• C. Infected people should wash hands consistently, keep fingernails short, avoid biting nails and scratching around anus
• D. Daily morning changing of bedsheets and underclothes and laundered in hot water/dryer is also recommended

Answer: (A)

Pinworm transmission occurs mainly through a fecal-oral route: eggs contaminate hands and surfaces, and when hands reach the mouth, infection can start or continue. The most effective way to break this cycle is thorough hand hygiene. Washing with soap and warm water after using the bathroom and before eating removes or inactivates eggs on the hands, reducing autoinoculation and spreading the infection to others and to the environment. Other measures can help, but they’re not as consistently protective on their own. Showering in the morning might remove some eggs from the skin but doesn’t address eggs under the nails or on contaminated surfaces. Keeping nails short and avoiding nail-biting reduces the chance of carrying eggs, but without regular handwashing, transmission can still occur. Laundering bed linens and clothing helps environmental cleaning, yet hand hygiene remains the most important, practical step to prevent infection.
