The most common symptom of a pinworm infection is intense itching around the anus, but some individuals with pinworm infections may not experience any symptoms.
How long does pinworms last? The life cycle of a pinworm is 4 to 6 weeks. Without treatment, infestation will continue as long as fresh eggs are being swallowed, unless a person develops immunity to pinworms, which is unusual before age 15.
If left untreated, the intense itching and scratching associated with these infections will result in secondary bacterial infections. Some of these may be difficult to treat. Untreated people can continue to infect other people.
Most people infected with pinworms have no symptoms, but some people experience anal itching and restless sleep.
Your child may be fussy and wake often at night. If your child is infected, it may take 2 to 8 weeks for symptoms to start.
Summary. Pinworm is the most common worm infection in Australia. The major symptom is an itchy bottom, particularly at night. Treatment usually includes a single or 2-dose course of medication that should be taken by all members of the affected household.
Pinworm infection (called enterobiasis or oxyuriasis) causes itching around the anus which can lead to difficulty sleeping and restlessness. Symptoms are caused by the female pinworm laying her eggs. Symptoms of pinworm infection usually are mild and some infected people have no symptoms.
Threadworms do not go away by themselves, and people do not build up immunity to them, so they must be treated in order to eradicate them totally from the body.
Pinworms are also called “threadworms.” They're the most common type of intestinal worm infection in the U.S., and one of the most common in the world. They're thin and white, and about one-quarter to one-half inch long -- about as long as a staple. Tapeworms are flatworms that look a bit like ribbons.
Pinworms mostly reside in areas of the large intestine of humans but are sometimes found in the small intestine. The life expectancy of these worms is approximately four to eight weeks.
Pinworms can usually be treated completely with two doses of over-the-counter medicine called pyrantel pamoate, available in the United States under the brand names Pin-X and Reese's Pinworm Medicine.
When someone scratches the itchy area, tiny pinworm eggs get on their fingers. Contaminated fingers can then carry pinworm eggs to the mouth, where they go back into the body, or onto touched surfaces, where they can live for 2 to 3 weeks.
One way to detect pinworms is to shine a flashlight on the anal area. The worms are tiny, white, and threadlike. If none are seen, check for 2 or 3 additional nights.
It moves. If it doesn't wiggle, it's probably lint or a thread. The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning.
At night, the female adult worms deposit their eggs outside the rectum or anal area. One way to detect pinworms is to shine a flashlight on the anal area. The worms are tiny, white, and threadlike. If none are seen, check for 2 or 3 additional nights.
Although the diagnosis can be made during endoscopy, the more common diagnostic test is the cellophane tape test, in which eggs are identified. There are no estimates of the prevalence of pinworms during routine colonoscopy.
Occasionally, colonoscopy can reveal unexpected findings, including the presence of parasite infections, even if patients are asymptomatic. There have been a number of case reports where colonoscopy identified the presence of adult worms by direct visualization [4-11].
Pinworm is the most common worm infection in the United States. Humans are the only species that can transfer this parasite. Household pets like dogs and cats cannot become infected with human pinworms.
Adults are rarely affected, except for parents of infected children. Infection often occurs in more than one family member. While an infected person sleeps, female pinworms crawl out of the anus and lay their eggs on the surrounding skin.
According to the CDC, pinworms can survive for up to 2 to 3 weeks in the home. So parents…you have a lot of cleaning to do to get rid of that itchy feeling you just got, and to ensure your family does not re-infect themselves. Where should you start when it comes to cleaning your home post-pinworm infection?
While serious complications are rare, pinworms can lead to: Bacterial infections: When the infected person scratches the anal area, the skin can bleed and become infected. Urinary tract infections (UTIs): In females, the worms can travel to the vagina and cause infections.
People are most likely to get pinworms if they swallow their eggs. This can happen if a person with pinworms scratches around the anus. Then the person gets eggs on his or her hands or under the fingernails. You can then get pinworms if you touch that person or if you touch something he or she touched.
Scratching an affected area and then eating can lead to unintentionally ingesting pinworm eggs. This can lead to a repeat pinworm infection. Sometimes eggs on the anus hatch, and the larvae can reenter the large intestine. If not treated, this can cause the infection to continue indefinitely.
After a few weeks, the female pinworms move to the end of the large intestine, and they come out of the body at night to lay their eggs around the anus (where poop comes out). The amount of time that passes from when someone swallows the eggs until the worms lay new eggs is about 1 to 2 months.
