The human body is constantly exposed to external dangers. This is another type of disease, infection and so on. One of the most common, serious problems is parasites. They enter the body completely imperceptibly, the consequences can be very serious. It is important to know which parasites are the most dangerous in the human body, which are health hazards due to them. You can see the parasites in detail in the photo.
Different worms live around the world, all divided by mode of transmission, 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;
- circle;
- bar.
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 - live in venous blood
Another name for the parasite is flukes in the blood. The 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 often in South America, Africa, the Middle East, Southeast Asia. They are not large in size, 2, 6 cm long, 0, 6 mm in diameter, which is clearly visible in the photo. The 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 location of the body where the schistosomes have accumulated:
- nervous system - disorientation, memory loss, headache;
- bladder - inflammation of organs, blood in urine, abdominal pain;
- liver - ascites, enlargement of organs, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they break through, they damage the walls of lymphatic and blood vessels of various organs and tissues. In this way, parasites can also 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, and liver fibrosis. To avoid infection by the most dangerous parasites in the human body, it is very important to avoid bathing in tropical waters, wash vegetables, fruits and hands well before eating. Schistosomiasis can be treated conservatively 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 with dirty water from tropical reservoirs in Asia and Africa. Usually people are infected, but there are cases of dogs being infected.
The worm enters the human body by swallowing contaminated water, where copepods - carriers of larval larvae - live. Surgical treatment only. Secondary infection of already wounded skin is very dangerous.
Once in the body, the ridge literally penetrates 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 the parts of the body where the ridges are located, and parasites can be found inside them. The disease is caused only by females, males die after mating. When the infected area of skin comes in contact with water, the female worm comes out at a short distance and throws its larvae into the water. These larvae must be caught by copepod crabs in order to survive.
Filariae are very dangerous parasites for the body
Another name for the worm is filamentous. Of all the species, about 10 people prefer humans, which leads to filariasis. They are called threads because of their appearance, the worms are very thin, like threads, you can see it in the photo. Diameters 0, 3 cm, however, grow to great lengths, up to 50 cm or more. By hitting the body, they live in the subcutaneous tissue, body cavity, heart, blood, lymph vessels, any part of the body. Very often in hot countries.
They are transmitted by blood-sucking insects, sometimes ticks, which in turn infect 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. Accumulating, filariae block the lymphatic system, clog blood vessels, causing elephantiasis. The patient's legs become large, excessively swollen, 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 tapeworm lives in the intestines of dogs, wolves, rarely cats and is easily transmitted to humans.
Echinococcus larvae are one of the most dangerous, causing echinococcosis. The adult worm is 3 to 5 mm long, and the photograph describing the parasite clearly shows that it has a head with tits, hooks and segments. From the body of the canine, the eggs come out with the feces, sometimes reaching the wool.
Infection is also possible in livestock. Infection in humans occurs through the mouth, they eat contaminated meat, dog saliva. The larvae penetrate further into the body, enter the liver with blood, where they live and multiply. They rarely enter the 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 drugs or immediately by removing the tissue of the organ along with the vesicles of the larvae.
Whiskered Vandellia - the smallest and scariest
In general, this creature belongs to fish, but is one of the most dangerous to the body. People are afraid of it because during bathing it is almost transparent, a small creature 15 cm long easily penetrates the urethra, genitals and anus. Then Vandellia is tied to vessels and feeds on blood. Unfortunately, the only way to get rid of parasites is surgery.
Ascaris - the most famous worm of the human body
The parasite is widespread, often found in the human body. If the eggs of the human roundworm fall into the ground, they can be stored there for almost a year until they move to a favorable environment. It releases toxins in the body that affect the liver and lungs. Ascaris does not stop in one place, constantly travels through the body, affects blood vessels and causes inflammation.
The main habitat of the most harmful worm is the gut, where parasites live comfortably, eating the food an infected person eats. They can pass into the pancreas, bile, liver, reach the esophagus, block breathing. One roundworm lays up to 1000 eggs a day. They grow quite large lengths, up to 30 cm.
Taurus tapeworm is the largest and most dangerous worm
This very large parasite lives in the small intestine, the tapeworm photos are simply amazing. The body of the tapeworm consists of a head with tits, a large number of segments, numbering 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 in its life cycle.
It lives only in the small intestine of an animal, a human. The temporary host through which a person becomes infected is cattle. Infection occurs with poorly processed, cooked or raw meat, milk, fish, contact with pets.
Hookworm - a harmful, dangerous worm
The worm is very common in East Asia, Africa, and causes ankylosing spondylitis. The parasite lives in the human duodenum, does not grow large, at most 14 mm. Infection occurs with dirty hands, vegetables, fruits, even through the skin during work with the ground, while walking barefoot on the grass, the larvae penetrate the skin.
Once in the body it enters the blood vessels, thence into the liver, heart, lungs. Hookworm leads to serious complications, especially hepatitis, ulcers.
Wide tapeworm - a dangerous parasite with a large long body
Infection with this worm comes through fish, if a person has eaten raw, poorly cooked fish, raw pike caviar or has been processing infected fish, seafood.
Dangerous tapeworm 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 pumps with which the worm is attached to the intestines. Looking at a photo of a worm, it’s just hard to believe it can live in a human. The larva develops in just one month. Broad tapeworm leads to a serious disease - diphyllobotriasis.
The patient has a severe vitamin deficiency because the worm feeds on all the nutrients in the body. All his large body absorbs substances on its surface. At the place where the tapeworm 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 of the human body
This worm can be mistaken for beef tapeworm, but does not grow as large, a maximum of 3 meters in length. There are also fewer segments on the body, up to 1000. On the head of the worm there are suckers, proboscis with hooks. Thus, the tape is attached to the intestinal walls. It is rooted in the body of pigs, rabbits, hares, dogs, camels, through which it reaches the person - the final owner. Infection is allowed by using raw bacon, meat. It is very dangerous for eggs to enter the human body, as they become middle masters, the Fina phase occurs in it, which often leads to the most severe diseases and death.
Helminth causes cysticercosis, teniasis. If there are a lot of parasites, they clog the intestines, resulting in the patient needing urgent surgery. They can penetrate the intestinal walls, enter the lymphatic vessels and enter the internal organs. Complications of the problem lead to damage to the subcutaneous tissue, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to carry out prevention, carefully process the meat before eating. The person must respect personal hygiene, prevention of helminthiasis.
