Humans are the only host of threadworms. The adult worms live in the lower intestine, coming out of the anus at night to lay their eggs. Children with threadworms can get the eggs under their fingernails when scratching their itchy bottoms at night.
About half the world's population (over 3 billion people) are in infected with at least one of the three worms forming what Columbia University parasitologist Dickson Despommier calls the "unholy trinity"—large roundworm, hookworm and whipworm.

It takes about five months for larvae to become adult worms inside the human body. Larvae can become adults only inside the human body. The adult worms live between layers of connective tissue (e.g., ligaments, tendons) under the skin and between the thin layers of tissue that cover muscles (fascia).
Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms doesn't wash their hands.
Threadworms live about 5-6 weeks in the gut, and then die. However, before they die the female worms lay tiny eggs around the anus. This tends to be at night when you are warm and still in bed. The eggs are too small to see, but cause an itch around the anus.
The spread of worm infections
Threadworms are easily spread so the slightest contact can pass on the infection, which is why many adults end up with the same infection as their children. To halt the spread of worms, it's crucial to treat all members of the family – not just the youngsters!
It's rare in the United States but may occur in the rural Southeast. Infection occurs from contaminated food or water. Adult worms can grow more than a foot long. Usually, they don't cause symptoms.
But just 100 years ago, before toilets and running water were commonplace, everybody had regular exposure to intestinal worms. Thanks in part to modern plumbing, people in the industrialized world have now lost almost all of their worms, with the exception of occasional pinworms in some children.
Symptoms may include diarrhoea, tiredness and weakness, abdominal pain and weight loss. Some worms cause anaemia.
Nausea or vomiting. Gas or bloating. Dysentery (loose stools containing blood and mucus) Rash or itching around the rectum or vulva.
Sometimes worms are visible in the anal area, on underwear, or in the toilet. In stool, they look like small pieces of white cotton thread.

Intestinal worms (also known as soil-transmitted helminths) affect more than 1.7 billion people worldwide including more than 1 billion children, according to the World Health Organization. The three most common intestinal worms are hookworm, ascaris (roundworm), and trichuris (whipworm).
Doctors generally prescribe a single dose of albendazole tablets once every six months for children. It works for most parasitic worms in the gut except for tapeworm. Anti-worm products will only treat the adult worms currently residing in the intestines. They will not treat the eggs or immature worms.
Most of them are not a problem in Australia because of our climate and good standard of sanitation. Worms causing infection in people are parasites that live and breed mostly in the bowel (intestine). The most common worm in Australian children is the threadworm, Enterobius vermicularis, sometimes called the pinworm.
While Australia is free from many serious human parasitic diseases there are some parasites that we often encounter and are forced to deal with: Head lice. Dog Hookworm. Paralysis tick.
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.
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.
Rope worms are long, rope-like structures that sometimes occur in the intestines. According to some scientists, they are parasitic worms, but it is more likely that they are nothing more than a buildup of intestinal mucus and other debris.
Itching during the night in a child's perianal area strongly suggests pinworm infection. Diagnosis is made by identifying the worm or its eggs. Worms can sometimes be seen on the skin near the anus or on underclothing, pajamas, or sheets about 2 to 3 hours after falling asleep.
To diagnose a tapeworm infection, doctors will collect and examine a stool sample on 3 different days to check for tapeworm eggs or pieces of worm. They may also do a blood test. If a child could have cysticercosis, the doctor might recommend a CT (CAT) scan or MRI of the brain or other organs to look for cysts.
Once in the body, the worms find their way to the small intestine and lay eggs. Those eggs hatch before they are pooped out and the worms may infect someone else. Often there aren't any symptoms, but the worms can cause: Belly pain.
