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.
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.
Tapeworms are the flatworms that live in the human digestive tract. If you suspect you might have tapeworms, you need to visit a doctor for stool sample analysis, a blood test, and imaging tests.
Factors that may put you at greater risk of tapeworm or larval cyst infection include: Eating raw or undercooked meats. The main risk factor for tapeworm infection is eating raw or undercooked meat and fish. Dried and smoked fish also may have larval cysts in them.
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.
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).
Tapeworms are uncommon in the U.S. today because of laws on feeding practices and inspection of the animals we use for food. You can further reduce your risk of tapeworms by washing your hands before and after using the toilet and by following these food safety tips. Avoid raw fish and meat.
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.
If your doctor confirms you have a tapeworm infection, follow their instructions to lessen the risk of complications. If left untreated, there's the risk of developing an invasive infection which can affect your tissue and organs. This can lead to brain swelling, inflammation, and intestinal blockage.
Anyone who has a tapeworm will need medical treatment to get rid of it. Treatment is about 95% effective and typically takes a few days.
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.
In rare cases, tapeworm segments become lodged in the appendix, or the bile and pancreatic ducts. Infection with T. solium tapeworms can result in human cysticercosis, which can be a very serious disease that can cause seizures and muscle or eye damage.
Left untreated, adult tapeworms can live in a host body for up to 30 years.
The adult tapeworm is made up of many small segments, called proglottids, each about the size of a grain of rice. Adult tapeworms may measure 4-28 inches in length.
Symptoms of cysticercosis depend on the location and size of the cysts, and can range from no symptoms at all to tender lumps under the skin to headaches, seizures, stroke or death.
Another less common group of tapeworms called Echinococcus is of increasing concern as a threat to human health. These tapeworms cause serious, potentially fatal disease when humans become infected.
"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.
For the most common types of worms, including roundworms, hookworms, whipworms and tapeworms, there are all-in-one medications for your dog (allwormers) in flavoured chewable tablets which will kill the existing infestation.
For most people, treatment will involve taking a single dose of a medication called mebendazole to kill the worms.
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.
As disgusting as tapeworms are, the vast majority of them are not contagious to people and do not cause any significant problems to cats.
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.
This infection occurs after a person swallows tapeworm eggs. The larvae get into tissues such as muscle and brain, and form cysts there (these are called cysticerci). When cysts are found in the brain, the condition is called neurocysticercosis.
