They enter the body completely unnoticed, the consequences can be very serious. Importers It is important to know which parasites in the human body are the most dangerous, what are the health threats due to them. You can see the parasites in detail in the picture.
Different worms live all over the world, all are divided according to the mode of transmission, the type. Parasitic worms are transmitted to humans mainly in the following ways:
- infected person;
- animals;
- land, food, water;
- insect bites.
Worms are divided into several types:
- rrymat;
- round; tape
- .
Worms are a very large class of parasitic worms that live on plants, animals and humans. They can live in empty organs, thicker tissues, the tissues themselves.
Top 10 most dangerous parasites in the human body

- Rishta is a worm that lives under human skin.
- Echinococcus are dangerous larvae in the body.
- Whiskered Vandellia is a fish parasite.
- Roundworms are known for all worms.
- Bovine tapeworm is a very large and tall worm. Ankylosing spondylitis is a small, harmful worm.
- Wide tape - a danger to the human intestine.
- Swine fever is a dangerous disease.
Schistosomes - living in venous blood
The second name of the parasite is blood. Infection occurs through the skin, contact with contaminated water. The disease caused by schistosomiasis is called schistosomiasis.
They differ from other helminths in their habitat: they live and multiply in the venous system. Most common in South America, Africa, Middle East, Southeast Asia. They are not large in size, length 2. 6 cm, diameter 0. 6 mm, which is clearly visible in the picture. A person realizes that they are infected with the following symptoms:
- bowel disorder;
- enlarged lymph nodes, spleen.
But the symptomatology is different, it all depends on the place of the body where the schistosomes are gathered:
- nervous system - disorientation, memory loss, headache;
- urinary bladder - inflammation of organs, blood in urine, abdominal pain;
- liver - ascites, organ enlargement, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they pierce, damage the walls of lymphatic vessels and blood of various organs and tissues. This way, the parasites can even enter the uterus, lungs, prostate and stomach. Worms, eggs block blood vessels, which leads to the formation of varicose veins, tumors, cysts. Helminths of this type can lead to serious problems, including cancer of the bladder, liver, prostate, liver fibrosis. To avoid infection with the most dangerous parasites of the human body, it is very important to avoid swimming in tropical waters, wash vegetables, fruits and hands well before eating. Schistosomiasis can be cured conservatively if treatment is started on time. In case of complications, operations are performed.
New - subcutaneous worm
Dracunculiaza is a disease caused by this type of parasite in the human body. Infection occurs through contaminated water from tropical reservoirs in Asia and Africa. Usually humans are infected, but there are cases of dog infection.
The worm enters the human body when it swallows polluted water, where coppods live - carriers of young larvae. Treatment only with surgery. Secondary infection of already injured skin is very dangerous.
Once introduced into the body, the newcomer literally digs through the tissues, intestinal walls, lives in the lymph vessels, subcutaneous fat. In length, the worm can grow large, up to 80 centimeters. Strong abscesses appear in areas of the body where they are newly located, and parasites can be found within them. The disease is caused only by females, males die after mating. When an infected area of skin comes in contact with water, the female worm comes out at a short distance, throwing its larvae into the water. These larvae must be caught by copepod lobsters in order to survive.
Filariae is a very dangerous parasite for the body
Another name for the worm is filamentous. Of all the species, about 10 prefer humans, leading to filariasis. They were called threads because of their appearance, the worms are very thin, like a thread, you can see this in the picture. 0, 3 cm in diameter, however, they grow to great lengths, up to 50 cm or more. After hitting the body, they live in the subcutaneous tissue, body cavity, heart, blood, lymph vessels, every part of the body. Very common in hot places.
They are transmitted through blood-sucking insects, sometimes ticks, which in turn become infected through the blood of an infected, human animal. The danger lies in the fact that the most horrible worms can be detected when the disease has become chronic, it is almost impossible to cure it. Accumulating, filariae block the lymphatic system, block blood vessels, causing elephantiasis. The patient's legs become large, swollen excessively, to the point of inability to move, there are many pictures of people with this disease online.
Echinococcus is a major threat to humans and animals
This tape lives in the intestines of dogs, wolves, rarely cats and can easily be transmitted to humans.
Echinococcus larvae are one of the most dangerous, causing echinococcosis. An adult worm is 3 to 5 mm long, in the picture depicting the parasite, it is clearly visible that it has a sucker head, hooks and segments. From the dog's body, eggs come out in the feces, sometimes getting into the fur.
Infection is also possible through livestock. Infection occurs in humans through the mouth, eating contaminated meat, dog saliva. The larvae penetrate further into the body, through the blood enter the liver, where they live and multiply. Rarely do we get into bones, muscles, lungs. As they develop, echinococci turn into large bubbles the size of a child's head. Depending on the neglect of the disease, treatment is carried out with medication or immediately, removing the tissues of the organ along with the larval blisters.
Whiskered Vandellia - the smallest and most horrible
In general, this creature belongs to the fish, but it is one of the most dangerous to the body. People are afraid of it because during bathing, an almost transparent, small creature 15 cm long can easily penetrate the urethra, genitals and anus. Then Vandellia is attached to the vessels and fed with blood. Unfortunately, the only way to get rid of the parasite is through surgery.
Ascaris - the most famous worm of the human body
The parasite is widespread, often found in the human body. If the eggs of a human roundworm fall to the ground, they can be stored there for nearly a year until they move to a favorable environment. In the body, it releases toxins that affect the liver and lungs. Ascaris does not stop at one place, constantly travels through the body, affects blood vessels and causes inflammation.
The main place of life of the most harmful worm is the intestines, where the parasites live quietly, eating the food that the infected person eats. They can cross the pancreas, bile, liver, reach the esophagus, block breathing. A worm lays up to 1000 eggs a day. They grow quite tall in length, up to 30 cm.
Taurus is the biggest and most dangerous worm
This very large parasite lives in the small intestine, the strip photos are simply amazing. The body of the tapeworm consists of a sucker head, a large number of segments, which number from 2, 000 to 5, 000. The length of the worms increases continuously with growth, up to 10 meters. In the human body, without treatment, it can live up to 20 years. It produces about 600 million eggs a year, up to 11 billion per life cycle.
Lives only in the small intestine of an animal, of a human. The intermediate host through which a person becomes infected is livestock. Infection occurs through meat, milk, poorly processed fish, cooked or raw, through contact with pets.
Circle - a harmful, dangerous worm
The worm is very common in East Asia, Africa, it causes worm diseases. The parasite lives in the human duodenum, does not grow large, maximum 14 mm. Infection occurs through contaminated hands, vegetables, fruits, and even through the skin while working with the soil, when you walk barefoot on the grass, the larvae penetrate the skin.
Once it enters the body, it enters the blood vessels, from there it goes to the liver, heart, lungs. Ankylosing spondylitis leads to serious complications, especially in hepatitis, ulcers.
Broadband - a dangerous parasite with a long long body
Infection with this worm occurs through fish, if a person has eaten live fish, poorly cooked, raw point caviar or has been engaged in processing infected fish, seafood.
A dangerous band grows up to 15 meters in length, is very large, the body consists of a large number of segments - up to 4, 000, on the head there are suckers with which the worm is attached to the intestines. Looking at the picture of the worm, it is simply hard to believe that it can live inside a person. The larva develops in just one month. Wide tape leads to a serious disease - difilobotriasis.
The patient has a severe vitamin deficiency because the worm feeds on all the nutrients in the body. His entire large body absorbs the substances on its surface. At the site where the strips were sucked, necrosis begins. The most dangerous tapeworm can live in the human body for up to 10 years.
Pig tapeworm is a very harmful worm of the human body
This worm can be confused with a bovine tapeworm, but it does not grow that big, up to 3 feet tall. There are even fewer segments on the body, up to 1, 000. On the worm's head there are suckers, a proboscis with hooks. Thus, the tape attaches to the intestinal walls. It takes root in the body of pigs, rabbits, rabbits, dogs, camels, through which it passes to the person - the ultimate owner. Infection is permissible through the use of raw bacon, meat. Summer very dangerous for eggs to enter the human body, as it becomes an intermediate master, the stage of the Finns occurs in it, which often leads to the most serious diseases and death.
Helminth causes cysticercosis, tenacity. If there are many parasites, they block the intestines, as a result, the patient must be operated on urgently. They can pierce the intestinal wall, enter the lymphatic vessels, and enter the internal organs. Disease complications lead to damage to subcutaneous tissue, muscle, skin, spinal cord, brain, bone and internal organs. The most important thing is to carry out prevention, carefully process the meat before eating. A person should observe personal hygiene, prevention of helminthiasis.
