Threadworms, also known as pinworms, are small white parasites that live in the intestines of humans. They are the most common type of worm infection in children. While threadworms can be present in the intestines at any time, they tend to come out at night and lay eggs around the anus, which can cause itching.
Threadworms are transmitted through contact with contaminated objects, such as bedding, clothing, or toys. They can also be spread through direct contact with someone who has the infection or by consuming contaminated food or drinks.
Once the eggs are laid around the anus, they hatch within a few hours. The larvae then travel up the rectum and into the intestine, where they grow into adult worms. The adult worms then reproduce and lay more eggs around the anus. This cycle can repeat itself over and over again, resulting in the worms coming out every night.
In order to prevent reinfection, it is important to practice good hygiene. This includes washing hands after using the restroom, before eating, and after touching objects that may be contaminated. It is also important to clean the house regularly to prevent the spread of eggs. Additionally, the bedding and underwear of those infected should be changed and washed daily.
By practicing good hygiene and keeping the environment clean, threadworm infections can be prevented and the cycle of reinfection can be broken.
