Although not all infected people will have symptoms, many will experience itching around the rectum. Some females may also experience itching in the genital area. How soon do symptoms appear? Symptoms usually are noticed one to two months after infection.
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.
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.
The incubation period is usually 1–2 months; successive reinfections might be needed before symptoms appear. The most common symptom is perianal itching, which can be severe, causing sleep disturbances and irritability. Secondary infection of irritated skin also can occur.
Complications. Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals. The parasite can travel from the anal area up the vagina to the uterus, fallopian tubes and around the pelvic organs.
Remember that pinworms are quite common among kids and aren't harmful. By taking medicine and following some prevention tips, you'll be rid of the worms in no time.
So many of us or our family members have experienced this relatively mild though distressing infection.
The worm may be seen around the anus or on the child's bottom. It is especially active at night or early morning. Rarely, the pinworm is seen on the surface of a stool. The pinworm's secretions are a strong skin irritant and cause the itching.
It is more common in school-age children than pre- schoolers. 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.
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. The best way to diagnose this infection is to do a tape test.
The eggs stick to the tape. You then take the tape to your appointment so the doctor can look for pinworms or eggs under a microscope. Preparing a list of questions can help you make the most of your time with your doctor.
Threadworms often go unnoticed by people who have them. However, they can cause intense itching around the anus (and the vagina in girls), particularly at night when the female worms are laying eggs.
Most pinworm infections are mild and easily treated. Your doctor may prescribe a single chewable tablet of a medicine called mebendazole. A second tablet is taken about 3 weeks later if the infection isn't cured. Or your doctor may recommend another kind of medicine called pyrantel, which is taken as a single dose.
Pinworm infections often produce no symptoms but, when they occur, symptoms can include: itchy bottom, especially at night.
Yes. A pinworm infection can also be spread through: Bed sheets and undergarments: Eggs can spread through contact with contaminated sheets, towels or underwear of infected people. Inhalation: Because the eggs are so tiny, they can travel through the air and inhaled.
Sometimes pinworms can be seen around your anus or on your underwear or bed sheets about 2 to 3 hours after you've gone to bed. Most of the time, pinworms don't cause major problems. But in rare cases, they can cause infections of the vagina and uterus.
Because pinworms lay their eggs at night, washing the anal area in the morning can help reduce the number of pinworm eggs on your body. Showering may help avoid possible re-contamination in bath water. Change underwear and bedding daily. This helps remove eggs.
Pinworms can survive up to two weeks on clothing, bedding or other objects, if kept at room temperature.
If you or someone in your family has pinworms that keep coming back, or if more than one family member is infected, every member of your family or household should be treated. Follow-up care is a key part of your treatment and safety.
The key is to break the 6-week cycle of pinworm reinfection by killing any live pinworms and preventing the ingestion of eggs. A diagnosis should be confirmed before treating with medications. Medications kill only the adult worms and have no effect on developing eggs and larvae.
Prevention of Pinworms
Pinworm eggs can live on hard surfaces and in clothes and bedding for 2 to 3 weeks. In addition to your regular household cleaning, you'll want to take these steps to stop the spread: Pinworms lay their eggs at night. Wash your anal area in the morning to reduce the number of eggs on your body.
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.
Pinworms do not cause abdominal pain, bloody bowel movements,fevers, or poor appetite. If the person has any of these signs or symptoms, they may have a more serious condition and should call a doctor or visit the hospital's emergency department.
