Pinworm (intestinal parasite) infections generally occur when personal hygiene rules are not followed and can spread easily. Comprehensive hygiene practices are of great importance to protect against these parasites, which tend to live under the fingernails.

To prevent pinworm infections, the following measures should be taken:

* Hand Hygiene: Wash hands thoroughly with soap and water frequently, especially after using the toilet and before preparing meals. Avoid finger or thumb sucking and nail-biting habits, and keep nails short and clean.
* Clothing and Linen Hygiene: Daily change underwear, pajamas, towels, and bedding; wash them with hot water and dry them at high temperatures.
* Food Safety: Do not consume undercooked meat and meat products. Wash raw vegetables and fruits thoroughly. Consume safe water and food from reliable sources.
* Anal Region Hygiene: Avoiding scratching the anal region is critically important to prevent the spread of the parasite's eggs.
