Contact with an infected person or animal's stool can also spread tapeworms. Pinworms may spread when a person comes into contact with an affected individual's anus, contaminated bedding, clothing, food, or other items. Washing hands with soap and water and cooking food thoroughly can help to avoid infection.
In general, the mode of tapeworm transmission from pet to person is due to close physical contact such as allowing a pet to lick you or letting it sleep on your bed which causes accidental ingestion of the tapeworm eggs. Contact with cat or dog faeces also carries a risk, as is eating unwashed wild foods.
Invasive infection
If tapeworm larvae have migrated out of your intestines and formed cysts in other tissues, they can eventually cause organ and tissue damage, resulting in: Headaches. Cystic masses or lumps. Allergic reactions to the larvae.
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).
People can pass tapeworm eggs to others when they don't wash their hands after using the bathroom. Tapeworm eggs in feces can then spread into food or onto surfaces like doorknobs.
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.
Left untreated, adult tapeworms can live in a host body for up to 30 years.
It's important to note that some tapeworm infections don't require treatment. Sometimes, the tapeworm leaves the body on its own. This is why some people never have symptoms or only have mild symptoms. If a tapeworm doesn't leave your body, your doctor will recommend a treatment based on the type of infection.
Some people with tapeworm infections never need treatment, for the tapeworm exits the body on its own. Others don't realize they have it because they have no symptoms. However, if you're diagnosed with intestinal tapeworm infection, medication will likely be prescribed to get rid of it.
Eating undercooked meat from infected animals is the main cause of tapeworm infection in people. Although tapeworms in humans usually cause few symptoms and are easily treated, they can sometimes cause serious, life-threatening problems.
If you have a tapeworm infection, you may not have any symptoms. But some people have nausea, stomach pain, weakness, or diarrhea. You might notice a change in appetite (eating more or less than usual). And since the tapeworm keeps your body from absorbing nutrients from food, you may lose weight.
Yes; however, the risk of infection with this tapeworm in humans is very low. For a person to become infected with Dipylidium, he or she must accidentally swallow an infected flea. Most reported cases involve children. The most effective way to prevent infections in pets and humans is through flea control.
Regardless of how regal they may seem, cats can carry worms and kissing your pet on their fur or head can lead to the transfer of worms to people.
Worms that affect dogs are not typically transmitted to people by licking, but licking can transmit other types of infectious diseases (e.g. bacterial infections).
Humans become infected by eating raw or undercooked infected beef or pork. Once ingested, cysticerci attach to the small intestine and develop into adult tapeworms over the course of 2 months. The adult tapeworms produce proglottids that mature, detach, and migrate to the anus and are then passed in the feces.
The Spirometra tapeworm can live in humans for up to 20 years. A man in China experienced seizures and other mysterious symptoms for years before doctors finally found the cause: He had a rare parasite living in his brain, which had likely been there for more than a decade, according to news reports.
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).
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.
An adult dwarf tapeworm can live for 4-6 weeks. However, once you are infected, the dwarf tapeworm may reproduce inside the body (autoinfection) and continue the infection.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites.
People can also contract hookworms. Like tapeworms, hookworms can enter humans by being accidently consumed (for example, after petting your flea-infested dog or cat). Hookworm larvae can also burrow into your skin if you walk across a contaminated area in your bare feet.
Ingesting Fleas
It's also possible for tapeworms to be transmitted directly from pets to humans; we can become infected with the flea tapeworm if we eat an infected flea by accident, often through playing or sleeping with our pet.
Because cats are not feces eaters (coprophagic), humans are unlikely to become infected by parasites from their cats. Giardia and Cryptosporidia are immediately infective so potentially could be transmitted by a lick.
