These infections are not common in Australia, and are usually only acquired overseas. Dog tapeworms (Echinococcus granulosus) are yet another type of tapeworm. They can infect humans who accidentally ingest the tapeworm's eggs, which are released from dog or dingo stools.
In Australia, the causative tapeworms are considered endemic in wildlife animals, however, there have been only five reported human infections.
The most common tapeworm infection in Australia is caused by dwarf tapeworm. There is also a risk in Australia of contracting a serious condition called hydatid disease from the eggs of a type of tapeworm called Echinococcus granulosus found in dog faeces (poo).
There are many worms worldwide that can infest the bowels of people. 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).
Tapeworm infections are rare in the United States. When they do happen, they're easy to treat. Often, people may not know they have a tapeworm infection because they have no symptoms or their symptoms are mild.
Complications. The most serious symptoms happen when tapeworm larvae invade parts of your body outside the intestines. You may have serious problems with your nervous system, including seizures, or you could get headaches, masses or lumps, allergic reactions to the larvae, or problems with your vision.
Tapeworm infections usually don't cause complications. Problems that may happen include: Anemia. Long-term infection with a fish tapeworm may lead to the body not making enough healthy red blood cells, also called anemia.
"It's very rare, particularly in Australia. There's only one documented case of a type of fish tapeworm in Australia," Dr Ho said. "But in other countries, particularly in the northern hemisphere, people do get them." The longest type of tapeworm found in humans can grow to 10 metres and live for 20 years, Dr Ho said.
A person with intestinal worms may not have any symptoms, but threadworms (Enterobius vermicularis), the most common worm infection in Australia, often do cause symptoms. A person with threadworms (also known as pinworms) may have an itchy bottom or redness and scratch marks around the bottom.
Deworming is not always necessary, but is recommended for children who live in endemic areas once a year when the prevalence of soil-transmitted parasitic worms in the community is over 20% and twice a year when the prevalence of soil-transmitted parasitic worms in the community is 50%.
A tapeworm infection is usually diagnosed by finding eggs or tapeworm segments in the stool. Your doctor may ask you to bring in a sample so a lab can look for eggs, larvae, or tapeworm segments. A blood test can spot antigens, foreign substances that let your doctor know your body is trying to fight the infection.
You can easily kill tapeworms with anthelmintic drugs, including praziquantel (Biltricide®), albendazole (Albenza®) and nitazoxanide (Alinia®). Healthcare providers usually recommend praziquantel because it also paralyzes the worm, forcing it to dislodge from your intestinal wall.
How long does it take for tapeworm symptoms to develop? Sometimes, tapeworm symptoms develop within a few months of the parasite taking up residence in your intestine.
People who live in close proximity to livestock or free-range animals and/or have poor sanitation have a greater risk of developing a tapeworm infection. Tapeworm infections are more common in developing areas of the world where sanitation is poor and people may eat undercooked meats.
The cure rate for tapeworm infestation is greater than 95% in patients who receive appropriate treatment. The prognosis for systemic cysts depends on the location of the cysts.
Tapeworm infections due to T. solium are more prevalent in under-developed communities with poor sanitation and where people eat raw or undercooked pork.
The best way to diagnose this infection is to do a tape test. The best time to do this is in the morning before bathing, because pinworms lay their eggs at night. Steps for the test are: Firmly press the sticky side of a 1-inch (2.5 centimeters) strip of cellophane tape over the anal area for a few seconds.
If you have worms, a GP will prescribe medicine to kill them. You take this for 1 to 3 days. The people you live with may also need to be treated. Any worms in your gut will eventually pass out in your poo.
The most common type of human worm infection in Australia is pinworm. Other names for this parasite include threadworm and Enterobius vermicularis, or the common term 'worms'.
Take the correct dewormer
When infected with worms, it should be dewormed periodically, for adults and children over 2 years old should be dewormed 2 to 3 times a year, ie every 4 to 6 months.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Diagnosis of tapeworm infection
A health care provider tests for a tapeworm infection in the intestines using a test of a stool sample. A lab test may find pieces of tapeworms or eggs. You may give a sample on more than one day.
Many times, people can be infected for long periods of time without even knowing they have a tapeworm infection. While viral or bacterial infections can disappear in a matter of days or weeks, a tapeworm could be with you for years.
But could a tapeworm really be lured out of a person with a lump of meat? Not really, according to Brian Louden, from Science Channel's MythBusters. “Luckily, this entire idea is from the imagination of a creative individual who took already scream-inducing diseases and created a terrifying chimera,” he told TheWrap.
