The human body is constantly exposed to dangers from the outside. It is another type of disease, infection and so on. One of the most common, most serious problems is parasites. They get into the body completely unnoticed, the consequences can be very serious. It is important to know which parasites are most dangerous in the human body and what health risks they pose. You can see the parasites in detail in the photo.
Different worms live all over the world, each divided into the mode and type of transmission. Parasitic worms spread to humans mainly by the following methods:
- infected person;
- animals;
- soil, food, water;
- insect bite.
Worms can be divided into several types:
- flukes; 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.

- Rishta is a worm that lives under human skin.
- Filariae is a dangerous parasite of elephantiasis.
- Echinococci are dangerous larvae in the body.
- The foamy Vandellia is a fish parasite.

- Swine tapeworm is a dangerous disease.
Schistosomes - live in venous blood
The second name of the parasite is bloody. 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 reproduce in the venous system. Most common in South America, Africa, the Middle East, Southeast Asia. Its size is not large, length 2, 6 cm, diameter 0, 6 mm, which can be clearly seen in the photo. A person realizes that they are infected with the following symptoms:
- intestinal disorder;
- enlarged lymph nodes, spleen.
But the symptoms are different, it all depends on where the systems are located in the body:
- nervous system - disorientation, memory loss, headache;
- bladder - inflammation of the organs, blood in the urine, abdominal pain;
- liver - ascites, enlargement of the organ, spleen;
- intestines - diarrhea, octopuses.
Worm eggs are very dangerous, they pierce and damage the lymphatic and vascular walls of various organs and tissues. In this way, the parasites can even enter the uterus, lungs, prostate and stomach. Worms, oocytes clog blood vessels, leading to varicose veins, tumors and cysts. These types of helminths can lead to serious problems including 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 and to wash vegetables, fruits and hands thoroughly before meals. Schistosomiasis can be cured conservatively if treatment is started on time. In case of complications, actions are performed.
Rishta - subcutaneous worm
Dracunculiasis is a disease caused by these types of parasites in the human body. Infection occurs through the dirty waters of tropical reservoirs in Asia and Africa. Usually people are infected, but there are cases where dogs are infected.
The worm enters the human body, where copepods live, when they swallow contaminated water - carriers of rishta larvae. Surgical treatment only. Secondary infection of already wounded skin is very dangerous.
Once in the body, rishta literally chews through tissues, intestinal walls, lives in the lymphatics, and fat under the skin. In length, the worm can grow up to 80 centimeters. Strong abscesses appear in the areas of the body where the rishta is located and there are parasites in them. The disease is caused only by females, males die after mating. When the infected skin surface comes in contact with the water, the female worm goes out a short distance, throwing its larvae into the water. These larvae must be caught by copepoda crabs in order to survive.
Filariae is a very dangerous parasite for the body
Another name for the worm is filamentous. Of all species, about 10 people prefer to develop filariasis. Because of their appearance, they were called threads, the worms are very thin like a thread, you can see this in the photo. They are 0. 3 cm in diameter, but grow to great lengths, up to 50 cm or more. When they hit the body, they live in the tissues under the skin, in the body cavity, in the heart, in the blood, in the lymphatics, in any part of the body. It is very common in hot countries.
They are spread by blood-sucking insects, sometimes ticks, which in turn become infected with the blood of an infected animal, a human. The danger is that the worst worms can be detected when the disease has become chronic, it is almost impossible to cure. Accumulating filarias occlude the lymphatic system, clogging blood vessels, causing elephantiasis. The patient’s legs will be large, swollen excessively, to immobility, there are many photos on the internet of those suffering from the disease.
Echinococcus poses a major threat to humans and animals
This tapeworm lives in the intestines of dogs, wolves, rarely cats, and is easily transmitted to humans.
Echinococcal larvae are one of the most dangerous, causing echinococcosis. An adult worm is 3–5 mm long, and the photo describing the parasite clearly shows that it has a head with suckers, hooks, and segments. From the body of the canines, eggs are excreted in the feces, sometimes on the wool.
Infection is also possible through livestock. Infection occurs in humans through oral consumption of contaminated meat and dog saliva. The larvae continue to penetrate the body, entering the liver through the blood, where they live and reproduce. They rarely get into the bones, muscles, lungs. As it develops, the echinococcus become large bubbles corresponding to the child's head. Depending on the neglect of the disease, treatment is done with medication or immediately by removing organ tissues and larval bubbles.
Mustache Vandellia - the smallest and most horrible
This creature usually belongs to fish, but it is one of the most dangerous to the body. People are afraid of it because while bathing, an almost transparent, 15 cm long little creature can easily penetrate the urethra, genitals and anus. Vandellia then connects to the blood vessels and feeds on blood. Unfortunately, the parasite can only be rid of by surgery.
Ascaris - the most famous worm in the human body
The parasite is widespread and often found in the human body. If the eggs of a human nailworm fall into the soil, they can be stored there for almost a year until they are placed in a favorable environment. It releases toxins in the body that affect the liver and lungs. Ascaris does not stop in one place, it constantly walks the body, affects the blood vessels and causes inflammation.
The main site of the most harmful worm is the intestines, where the parasites live comfortably, consuming the food consumed by the infected person. They can pass through the pancreas, bile, liver, reach the esophagus, block breathing. A nail worm lays up to 1, 000 eggs a day. They are long, growing up to 30 cm.
The bull tapeworm is the largest and most dangerous worm
This very large parasite lives in the small intestine, the photos of the tapeworm are simply amazing. The body of the tapeworm consists of a head with suction cups, a large number of segments ranging in number from 2, 000 to 5, 000. The length of the worm increases continuously as it grows, up to 10 meters. It can live in the human body for up to 20 years without treatment. Generates about 600 million eggs a year, up to 11 billion eggs per life cycle
Only one animal lives in the small intestine of a human. The intermediate farmer through which a person becomes infected is cattle. Infection occurs through contact with poorly processed, cooked or raw meat, milk, fish, pets.
Hookworm - a harmful, dangerous worm
The worm is very common in East Asia, Africa, causing hookworm diseases. The parasite lives in the human duodenum, does not grow large, up to 14 mm. Infection occurs through dirty hands, vegetables, fruits, or even through the skin, while working with the soil when you walk barefoot on the grass, the larvae penetrate the skin.
Once in the body, it enters the blood vessels, from there it enters the liver, heart, and lungs. Ankylostomosis leads to serious complications, especially hepatitis, ulcers.
Wide band - a dangerous parasite with a large, long body
Worms are infected through fish if someone has eaten raw, poorly cooked fish, raw pike, or infected fish, processing seafood.
The dangerous tapeworm grows to 15 meters, is very large, consists of a large number of segments of the body - up to 4000 - and has suckers on the head with which the worm is connected to the intestines. Looking at the photo of the worm, it is simply hard to believe that one can live inside. The larva develops in less than a month. The broad 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. Every large body absorbs substances on its surface. Necrosis begins at the site of tapeworm extraction. The most dangerous tapeworm can live in the human body for up to 10 years.
Swine tapeworm is a very harmful worm of the human body
This worm can be confused with a bovine tapeworm, but it does not grow as large as 3 meters in length. There are also fewer segments on the body, up to 1000. There are suckers and proboscis with hooks on the head of the worm. Thus, the tapeworm attaches to the intestinal wall. It takes root in the bodies of pigs, rabbits, hares, dogs, camels, through which it reaches man - the ultimate owner. Infection is allowed using raw bacon and meat. It is very dangerous for oocytes to enter the human body as it becomes an intermediate master, the Finnish stage occurs in it, which often leads to the most serious illnesses and deaths.
Helminth causes cysticercosis, teniasis. If there are many parasites, the intestines are clogged, and as a result, the patient needs to be operated on urgently. They can penetrate the intestinal walls, enter the lymphatics and internal organs. Complications of the diseases lead to damage to the subcutaneous tissues, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to do prevention, to process the meat carefully before eating. A person must adhere to personal hygiene, prevention of helminthiasis.
