They enter the body completely unnoticed, the consequences can be very serious. 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 photo.
Different worms live all over the world, they are all divided according to the mode of transmission, the type. Parasitic worms are transmitted to humans mainly in the following ways:
- infected person?
- animals?
- soil, food, water?
- insect bites.
Worms are divided into several types:
- flukes;
- round?
- cassette.
Worms are a very large class of parasitic worms that live on plants, animals and humans. They can live in hollow organs, thicker tissues, the tissues themselves.

- Pork tapeworm is a dangerous disease.
Schistosomes - live in venous blood
The second name of the parasite is blood. Infection occurs through the skin, in 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, the Middle East, Southeast Asia. They do not have a large size, length 2, 6 cm, diameter 0, 6 mm, which is clearly visible in the photo. A person realizes that they are infected with the following symptoms:
- bowel disorder?
- enlarged lymph nodes, spleen.
But the symptoms are different, it all depends on the position of the body where the schistosomes have accumulated:
- nervous system - disorientation, memory loss, headache.
- cyst - inflammation of organs, blood in urine, abdominal pain
- liver - ascites, swelling of the organ, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they penetrate, destroy the walls of lymph and blood vessels of various organs and tissues. In this way, parasites can even enter the uterus, lungs, prostate and stomach. Worms, eggs clog blood vessels, which leads to the formation of varicose veins, tumors, cysts. Worms of this type can lead to serious problems, such as bladder cancer, 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, to wash vegetables, fruits and your hands very well before eating. Schistosomiasis can be treated conservatively if treatment is started early. In case of complications, surgeries are performed.
Rishta - subcutaneous worm
Dracunculiasis is a disease caused by this type of parasite in the human body. Contamination occurs through the dirty water of tropical reservoirs in Asia and Africa. Usually humans are infected, but there are cases of dogs that are infected.
The worm enters the human body when swallowing contaminated water, where live rhoda larvae - carriers. Treatment only with surgery. Secondary infection of already injured skin is very dangerous.
Once found in the body, rishta literally gnaws on tissues, intestinal walls, lives on lymph vessels, subcutaneous fat. In length, the worm can grow up to 80 cm. Strong abscesses appear in the areas of the body where the rishta are located and parasites can be found inside 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 a short distance away, throwing its larvae into the water. These larvae must be caught by copepod crayfish to survive.
Filariae is a very dangerous parasite for the body
Another name for the worm is nematode. Of all the species, about 10 prefer humans, leading to filariasis. Named yarn because of their appearance, the worms are very thin, like a yarn, you can see it in the photo. 0. 3 cm in diameter, however, grow to a length of up to 50 cm or more. Having struck the body, they live in the subcutaneous tissue, the body cavity, the heart, the blood, the lymph vessels, in any part of the body. Very common in hot countries.
They are transmitted through blood-sucking insects, sometimes ticks, which in turn become infected through the blood of an infected animal, a human. The danger lies in the fact that the most terrible worms can be detected when the disease has become chronic, it is almost impossible to cure it. Accumulation, scabs block the lymphatic system, clog blood vessels, causing elephantiasis. The patient's legs become large, swollen too much, to the point of inability to move, there are many photos of people with this disease on the Internet.
Echinococcus is a great danger to humans and animals
This film lives in the intestines of dogs, wolves, rarely cats and can be easily transmitted to humans. 
Echinococcus larvae are one of the most dangerous, causing echinococcosis. An adult worm is 3 to 5 mm long, in the photo depicting the parasite, it is obvious that it has a head with a sucker, hooks and parts. From the dog's body, the eggs come out in the feces, sometimes entering the wool.
Infection is also possible through animals. The infection occurs in humans through the mouth, eating contaminated meat, dog saliva. The larvae penetrate further into the body, through the blood entering the liver, where they live and multiply. You rarely get into the bones, the muscles, the lungs. As they grow, echinococci turn into large bubbles the size of a child's head. Depending on the neglect of the disease, treatment is carried out with drugs or immediately, removing the tissues of the organ along with the bubbles of the larvae.
Whiskered Vandellia - the smallest and most terrible
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 in the bath, an almost transparent, small creature 15 cm long can easily penetrate the urethra, genitals and anus. Vandellia then attaches to the blood vessels and feeds on blood. Unfortunately, the only way to get rid of the parasite is through surgery.
Ascaris - the most famous worm in the human body
The parasite is widespread, often found in the human body. If the eggs of a human worm fall to the ground, they can be stored there for almost a year until they are moved to a favorable environment. In the body, it releases toxins that affect the liver and lungs. Ascaris does not stop in one place, it constantly travels through the body, affects the blood vessels and causes inflammation.
The main habitat of the most harmful worm is the intestine, where the parasites live comfortably, eating the food eaten by the infected person. They can pass into the pancreas, bile, liver, reach the esophagus, block breathing. One worm lays up to 1000 eggs a day. They grow quite large in length, up to 30 cm.
Taurus tape is the biggest and most dangerous worm
This very large parasite lives in the small intestine, the photos in the movie are just amazing. The body of the tape consists of a head with hoods, a large number of parts, ranging from 2, 000 to 5, 000. The length of the worm is constantly increasing 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, a human. The vector through which an individual is infected is bovine. Infection occurs through poor processing, cooked or raw meat, milk, fish, through contact with pets.
Hookworm - a harmful, dangerous worm
The worm is very common in East Asia, it causes hookworm disease. The parasite lives in the human duodenum, does not grow, maximum 14 mm. Infection occurs through dirty hands, vegetables, fruits, and even the skin while working on the ground, when you walk barefoot on the grass, the larvae penetrate the skin.
Once in the body, it enters the blood vessels, from where it goes to the liver, heart, lungs. Ankylosing spondylitis leads to serious complications, especially hepatitis, ulcers.
Wide ribbon - a dangerous parasite with a large long body
Infection with this worm occurs through fish, if a person ate raw, poorly cooked fish, raw pike caviar or was involved in the treatment of infected fish, seafood.
A dangerous tape grows up to 15 meters in length, it is very large, the body consists of a large number of parts - up to 4, 000, on the head there are absorbers with which the worm is attached to the intestines. Looking at the photo 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 can lead to a serious illness - bisexuality.
The patient has a severe vitamin deficiency because the worm feeds on all the nutrients in the body. His whole big body absorbs substances on its surface. At the point where the film has sucked, necrosis begins. The most dangerous film can live in the human body for up to 10 years.
Pork film is a very harmful worm to the human body
This worm may be confused with a bovine tapeworm, but it does not grow that big, with a maximum length of 3 meters. There are also fewer parts of the body, up to 1, 000. There are suckers on the worm's head, a proboscis with hooks. Thus, the tape is attached to the intestinal walls. It takes root in the bodies of pigs, rabbits, hares, dogs, camels, through which it reaches the individual - the ultimate owner. Infection is allowed with the use of raw bacon, meat. It is very dangerous for eggs to enter the human body, as it becomes an intermediate master, the Finnish stage appears in it, which often leads to the most serious diseases and death.
Elminthia causes cysticercosis, tension. They can penetrate the intestinal walls, enter the lymph vessels and enter the internal organs. Complications of the disease lead to damage to the subcutaneous tissue, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to prevent, to carefully process the meat before eating. A person must observe personal hygiene, the prevention of helminthiasis.
