It is important to know which parasites in the human body are the most dangerous, what are the threats to health 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:
moat- ;
- round;
- tape.
Worms are a very large class of parasitic worms that live in plants, animals and humans. They can live in hollow organs, thicker tissues, the tissues themselves.

Schistosomes - living in venous blood
The second name of the parasite is the blood fluke. Infection occurs through the skin on 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. More common in South America, Africa, the Middle East and Southeast Asia. They are not large in size, length 2. 6cm, diameter 0. 6mm, which is clearly visible in the photo. A person realizes that they are infected with the following symptoms:
- intestinal disorders;
- enlarged lymph nodes, spleen.
But the symptoms are different, it all depends on where in the body the schistosomes have accumulated:
- nervous system - disorientation, memory loss, headache;
- bladder - inflammation of organs, blood in the urine, abdominal pain;
- liver - ascites, organ enlargement, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they pierce, damage the walls of lymphatic and blood vessels of various organs and tissues. In this way, the 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. 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, to wash vegetables, fruits and hands thoroughly before eating. Schistosomiasis can be conservatively cured if treatment is started on time. In case of complications, operations are performed.
Rishta - subcutaneous worm
Dracunculiasis is a disease caused by this type of parasite in the human body. Infection occurs through dirty water from tropical reservoirs in Asia and Africa. Usually humans are infected, but there are cases of infected dogs.
The worm enters the human body by swallowing contaminated water, where copepods - carriers of the rishta larvae live. Treatment only by surgery. Secondary infection of already injured skin is very dangerous.
Once in the body, the rishta literally eats away at the tissues, the intestinal walls, lives in the lymphatic vessels, the subcutaneous fat. In length, the worm can grow large, up to 80 centimeters. Strong abscesses appear in areas of the body where rishta are found, and parasites can be found inside. 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, throwing its larvae into the water. These larvae must be captured by copepod crayfish 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 people prefer, lead to filariasis. They were called thread because of their appearance, the worms are very thin, like a thread, you can see in the photo. 0. 3 cm in diameter, however, they grow in length, up to 50 cm or more. After hitting the body, they live in the subcutaneous tissue, body cavity, heart, blood, lymphatic vessels, any part of the body. Very common in hot countries.
They are transmitted by blood-sucking insects, sometimes ticks, which in turn become infected with the blood of an infected animal, humans. 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. As they accumulate, heartworms block the lymphatic system, clog blood vessels, causing elephantiasis. The patient's legs grow large, swell excessively, until the 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 tapeworm lives in the intestines of dogs, wolves, rarely cats, and can easily be transmitted to humans.
Echinococcus larvae are among the most dangerous, causing echinococcosis. An adult worm is 3-5mm long, in the photo describing the parasite it is clearly visible that it has a head with suckers, hooks and segments. From the body of dogs, the eggs come out with feces, sometimes on the wool.
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 they enter the liver, where they live and multiply. Rarely get into bones, muscles, lungs. As they grow, echinococci turn into large bubbles the size of a child's head. Depending on the neglect of the disease, the treatment is carried out with drugs or quickly, removing the tissues of the organ as well as the bubbles of the larvae.
Whiskered Vandellia - the smallest and most terrible
In general, this creature belongs to fish, but it is one of the most dangerous for the body. People are afraid of her because during the bath, a small, almost transparent creature 15 cm long can easily enter the urethra, genitals and anus. Then Vandellia is attached to the 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 roundworm fall into the ground, they can be stored there for almost 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 in one place, constantly moves around the body, affects blood vessels and causes inflammation.
The main home of the most harmful worm is the intestine, where the parasites live comfortably, eating the food the infected person eats. They can pass into the pancreas, bile, liver, reach the esophagus, block breathing. A round worm lays up to 1, 000 eggs per day. They grow quite large, up to 30 cm.
Bull tapeworm is the biggest and most dangerous worm
This very large parasite lives in the small intestine, the pictures of the tapeworm are simply amazing. The body of the tapeworm consists of a head with suckers, a large number of segments, which number from 2000 to 5000. The length of the worm constantly increases with growth, up to 10 meters. In the human body, without treatment, it can live up to 20 years. It produces around 600 million eggs per year, up to 11 billion per life cycle.
Lives only in the small intestine of an animal, a human. The intermediate host through which a person is infected is cattle. Infection occurs through improperly processed, cooked or raw meat, milk, fish, through contact with domestic animals.
Hookworm - a harmful and dangerous worm
The worm is very common in East Asia, Africa, causes hookworm infection. The parasite lives in the human duodenum, does not grow, maximum 14 mm. Infection occurs with dirty hands, vegetables, fruits, even through the skin while working with the soil, walking barefoot on the grass, the larvae penetrate the skin.
Once in the body, it enters the blood vessels, from there it goes to the liver, heart, lungs. Hookworm disease causes 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, undercooked fish, raw pike caviar or was engaged in the processing of infected fish, seafood.
A dangerous tapeworm reaches 15 meters in length, it is very large, the body consists of a large number of segments - up to 4000, on the head there are suckers with which the worm is attached to the intestines. Looking at the photo of the worm, it is just hard to believe that it can live inside a person. The larva develops in just a month. Wide tapeworm leads to a serious disease - diphyllobothriasis.
The patient is severely deficient in vitamins, as the worm feeds on all the nutrients in the body. Its whole large body absorbs substances on its surface. Where the tapeworm has sucked, necrosis begins. The most dangerous tapeworm can live in the human body for up to 10 years.
Pork tapeworm is a very harmful worm in the human body
This worm can be mistaken for a bovine tapeworm, but it doesn't grow that big, maximum 3 meters long. There are also fewer segments on the body, up to 1000. On the head of the worm there are suckers, a proboscis with hooks. Thus, the tapeworm is attached to the intestinal walls. It takes root in the body of pigs, rabbits, hares, dogs, camels, through which it reaches the person - the final owner. Infection is allowed through the use of raw bacon, meat. It is very dangerous for the eggs to enter the human body, since it becomes an intermediate master, the Finnish stage occurs there, which often leads to the most serious diseases and death.
Helminths cause diseases of cysticercosis, tapeworm. If there are a lot of parasites, they clog the intestines, therefore, the patient must be urgently operated on. They can pierce the intestinal walls, enter lymphatic vessels, and enter internal organs. Complications of the conditions lead to damage to the subcutaneous tissue, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to do prevention, to treat the meat carefully before eating it. A person should observe personal hygiene, the prevention of helminthiasis.
