Humans swallow the eggs when they eat contaminated food or put contaminated fingers in their mouth. Importantly, someone with a tapeworm can infect him-or herself with tapeworm eggs (this is called autoinfection), and can infect others in the family.
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.
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.
Don't Worry, They're Rare
If the thought of tapeworms makes you squirm, take heart. You probably won't ever get one. Less than 1,000 people in the U.S. get them a year.
Animals who consume the eggs — including insects and fish — can incubate the tapeworm larvae. Humans become infected by accidentally ingesting the eggs or the larvae. People in less-developed countries with inadequate sewage treatment are more likely than others to get an infection by contamination from poop.
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.
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.
Eating affected meat or fish
If meat or fish have larvae cysts and are undercooked or raw, the cysts can travel to the human intestine, where they can mature into adult tapeworms. An adult tapeworm can : live as long as 25 years.
Treatment for tapeworms in humans
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.
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.
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.
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.
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.
The answer is yes. Unfortunately, even cats that never venture outside are still at risk for intestinal parasites like tapeworms and roundworms. That's why it's important to familiarize yourself with the types of worms your indoor cat could get, as well as the treatment options.
"After treatment, the tapeworm dies and is usually digested within the intestine, so worm segments do not usually pass into the stool." The deworming medication called an anthelmintic may be given as a tablet or an injection.
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 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).
Doctors in India were stunned to remove a tapeworm measuring more than 6 feet through a patient's mouth, according to a report published this week in the New England Journal of Medicine.
Your health care provider treats a tapeworm infection in the intestines with anti-parasitic drugs. These include: Praziquantel (Biltricide). Albendazole.
Tapeworms can cause digestive problems including abdominal pain, loss of appetite, weight loss, and upset stomach. The most visible sign of taeniasis is the active passing of proglottids (tapeworm segments) through the anus and in the feces.
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.
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.
