[20] However, reinfection is frequent regardless of the medication used. Most reptiles are oviparous and lay their eggs with tough covering and do not need to lay their eggs in water. [23] They are so effective that many medical scientists regard hygienic measures as impractical. Pinworm infection. Treating pinworms involves either prescription or over-the-counter drugs. [12] The male and female pinworms mate in the ileum (last part of the small intestine),[12] whereafter the male pinworms usually die,[18] and are passed out with stool. Some people who are infected do … [18] Individual eggs are invisible to the naked eye, but they can be seen using a low-power microscope. [9] In a heavy infection, female pinworms may adhere to stools that pass out through the anus, and they may thus be detected on the surface on the stool. While the infected person sleeps, female pinworms leave the intestinal tract and lay their eggs on the skin around the anus. [1] Other animals do not spread the disease.

[23] Children should wear gloves while asleep, and the bedroom floor should be kept clean. [11] Despite the limited, 13-week lifespan of individual pinworms,[12] autoinfection (infection from the original host to itself), either through the anus-to-mouth route or through retroinfection, causes the pinworms to inhabit the same host indefinitely. [29][30], This article is about the human infection with pinworms. Change and wash clothing and bedding frequently.

Encourage children to avoid scratching their bare anal areas. Tiny pinworm eggs can live on surfaces -- toys, bathroom fixtures, school desks, or bed linens -- for up to 3 weeks. [18] The estimations of the number of eggs in a gravid female pinworm ranges from about 11,000[12] to 16,000. The ingested eggs will travel down the large intestine, and they will hatch … [24] Pinworms located in the genitourinary system (in this case, female genital area) may require other drug treatments.

Pinworm infection, also known as enterobiasis, is a human parasitic disease caused by the pinworm. During their life cycle, the adults produce microfilariae measuring 250 to 300 μm by 6 to 8 μm, which are sheathed and demonstrate diurnal periodicity (organisms circulate in the bloodstream during the day and are non-circulating in the night). [12][17] Females survive for 5 to 13 weeks, and males about 7 weeks. [8], The relationship between pinworm infestation and appendicitis has been researched, but there is a lack of clear consensus on the matter: While Gutierres (2005) maintains that there exists a consensus that pinworms do not produce the inflammatory reaction,[15] Cook (1994) states that it is controversial whether pinworms are causatively related to acute appendicitis,[13] and Burkhart & Burkhart (2004) state that pinworm infection causes symptoms of appendicitis to surface.

[27] German botanist Lonicerus (1564) recommended garlic against parasitic worms. [11][17] According to Burkhart (2005), when this retroinfection occurs, it leads to a heavy parasitic load and ensures that the pinworm infestation continues. Because bathing or a bowel movement can remove the eggs, the tape test should be done as soon as the person wakes up in the morning. Seal in a plastic bag. [18] Infection may occur in the highest strata of society, where hygiene and nutritional status are typically high. [17] Pinworms are particularly common in children, with prevalence rates in this age group having been reported as high as 61% in India, 50% in England, 39% in Thailand, 37% in Sweden, and 29% in Denmark. [23] Pyrantel pamoate (also called pyrantel embonate, brand names e.g., Reese's Pinworm Medicine, Pin-X, Combantrin, Anthel, Helmintox, and Helmex) kills adult pinworms through neuromuscular blockade,[24] and is considered as effective as the benzimidazole compounds and is used as a second-line medication. 3.

Thus, a baby can easily pick up the worms by holding any object like a towel or a toy and can put her fingers in the mouth.
