It is important to know which parasites in the human body are the most dangerous, what are the health threats posed by them. You can see the parasite in detail in the photo.
Different worms live all over the world, they are all divided according to mode of transmission, type. Parasitic worms are transmitted to humans mainly through the following ways:
infected people- ;
- animals;
- soil, food, water;
- insect bites.
Worms are divided into several categories:
flukes- ;
- round; tape
- .
Worms are very large parasitic worms that live in plants, animals, and humans. They can live in hollow organs, thicker tissues, the same tissues.

Schistosomes - living in venous blood
The second name of the parasite is the blood fluke. Infection occurs through the skin, in contact with contaminated water. Diseases caused by schistosomiasis are called schistosomiasis.
They differ from other helminths in that they live and multiply in the venous system. Most common in South America, Africa, the Middle East, Southeast Asia. They are not large in size, 2, 6 cm long, 0, 6 mm in diameter, evident in the photo. A person finds themselves infected with the following symptoms:
- bowel disorders;
- enlarged lymph nodes, spleen.
But the symptoms vary, it all depends on the location of the body where schistosomes accumulate:
Nervous system- - disorientation, memory loss, headache;
- bladder - organ inflammation, blood hematuria, abdominal pain;
- liver - ascites, enlarged internal organs, spleen;
- intestines - diarrhea, polyps.
Worm eggs are very dangerous, they pierce and damage the lymph walls and blood vessels of various organs and tissues. In this way, the parasite can even enter the uterus, lungs, prostate, and stomach. Worms, eggs clog blood vessels leading to the formation of veins, tumors, cysts. These helminths can lead to serious problems, including bladder, liver, prostate, and cirrhosis of the liver. In order to avoid infection with the parasites most dangerous to the human body, it is very important to avoid swimming in tropical waters, and to wash vegetables, fruits and hands before eating. Schistosomiasis can be conservatively cured if treatment is started promptly. In the event of complications, operations are performed.
Rishta - subcutaneous worms
Worm disease is just a disease caused by this parasite in the human body. Infection occurs through dirty water in tropical reservoirs in Asia and Africa. Usually people are infected, but there are also cases where dogs are infected.
This worm enters the human body when swallowing contaminated water, where vertebrates are vertebrates - larvae carriers of the rishta species. Treatment only with surgery. Secondary infection of the injured skin area is very dangerous.
When entering the body, rishta will literally gnaw the tissues, intestinal wall, live in lymphatic vessels, subcutaneous fat layer. In length, the worm can grow large, up to 80 cm. Strong abscesses appear in areas of the body that have rishta and parasites can be found within them. The disease is caused only by the female, the male dies after mating. When the diseased skin comes into contact with water, the female worms go out briefly, throwing the larvae into the water. These larvae must be captured by crayfish in order to survive.
Filariae is a parasite that is very dangerous to the body
Another name for a worm is a filament. Out of all species, about 10 people prefer more, leading to filariasis. They are called threads because of their appearance, the worms are very thin, like a thread, you can see this in the photo. Diameter 0, 3 cm, however, they grow to large lengths, up to 50 cm or more. After attacking the body, they live in subcutaneous tissue, body cavity, heart, blood, lymphatic vessels, any part of the body. Very popular in hot country.
They are transmitted through blood-sucking insects, sometimes ticks, which are then infected through the blood of infected animals, humans. The danger lies in that, the most terrible worms that can be detected when the disease has turned chronic, is almost incurable. Accumulating, the worms only clog the lymphatic system, clog blood vessels, causing edema of the legs of the elephant. The patient's legs became so large, so swollen that he could not move, many photos of this patient appeared online.
Echinococcus is a great danger to humans and animals
This tapeworm lives in the intestines of dogs, wolves, rarely cats, and can be easily transmitted to humans.
The larvae of Echinococcus are one of the most dangerous species, causing echinococcosis. An adult worm from 3 to 5 mm long, in the photo depicting the parasite, it can be clearly seen that it has a head with tips, hooks, segments. From the canines, the eggs emerge in the feces, sometimes on wool.
Can also be transmitted by cattle. Human infection by mouth, eating contaminated meat, dog saliva. The larvae penetrate deeper into the body, through the bloodstream, they enter the liver, where they live and multiply. Rarely penetrates into bones, muscles, lungs. While growing, echinococci turn into bubbles as large as a child's head. Depending on whether the disease is ignored, treatment is carried out with drugs or promptly, by removing tissues of the organ along with bubbles of the larvae.
Whiskered Vandellia - smallest and most terrible
Overall, this creature is a fish, but it is one of the most dangerous to the body. People are afraid of her because during the bath, a small, almost transparent, 15 cm long creature can easily penetrate the urethra, genitals and anus. Then, Vandellia is attached to the vessels and eats blood. Unfortunately, the only way to get rid of parasites is through surgery.
Roundworm - the most famous worm on the human body
The parasite is widely available, usually found in the human body. If the eggs of the human roundworm fall into the soil, they can be stored there for nearly a year until they transition to a favorable environment. The body releases toxins that affect the liver and lungs. Roundworms do not stop in one place, but constantly move around the body, affecting the blood vessels and causing inflammation.
The main habitat of the most harmful worms is the intestines, where parasites live comfortably, and eat food that the infected person eats. They can go into the pancreas, bile, liver, to the esophagus, causing obstruction of breathing. A roundworm lays up to 1000 eggs per day. They are quite large in length, up to 30 cm.
The bovine tapeworm is the largest and most dangerous of all worms
This very large parasite lives in the small intestine, the pictures of tapeworms are simply amazing. The body of the tapeworm is composed of a head with vertebrae, a large number of segments, ranging in number from 2, 000 to 5, 000. The length of the worms constantly increases as they grow, up to 10 meters. In the human body, without treatment, it can live up to 20 years. It produces about 600 million eggs per year, up to 11 billion eggs per life cycle.
Only lives in the small intestine of animals, humans. The intermediate host to which a person is infected is cattle. Infection occurs through well-cooked, cooked or raw meat, milk, or fish, by contact with livestock.
Hookworms - a poisonous, dangerous worm
This type of worm is very common in East Asia, Africa, causing hookworm disease. The parasite lives in the human duodenum, does not grow large, up to 14 mm. Infected through dirty hands, vegetables, fruits, even through the skin when working with soil, walking barefoot on grass, the larvae penetrate the skin.
When it enters the body, it enters the blood vessels, from there to the liver, heart, and lungs. Adhesions lead to serious complications, namely hepatitis, ulcers.
Wide ribbon - a dangerous parasite with a large long stem
This worm infection occurs through fish, if a person eats raw, undercooked fish, raw caviar or is processing infected fish or seafood.
A dangerous tapeworm up to 15 meters in length, it is very large, the body consists of a large number of segments - up to 4, 000, on the head there are the ends to which the worm is attachedintestine. Looking at the worm's photo, it's hard to believe it can live inside a human. The larvae develop in just one month. Broad tapeworm leads to a serious disease - diphyllobothriasis disease.
Patients with severe vitamin deficiency, because the worms eat up the body's nutrients. All of its large bodies absorb substances on its surface. Where the tapeworm was injected began to necrosis. The most dangerous tapeworms can live in the human body for up to 10 years.
The pig tapeworm is a worm that is very toxic to the human body
It is possible to confuse this worm with a bovine tapeworm, but it does not grow too large, up to 3 meters in length. There are also fewer sections on the body, possibly up to 1, 000. On the deep head there are suction burns, the nozzle has hook. Thus, the tapeworm has attached to the intestinal wall. It is rooted in the bodies of pigs, rabbits, hares, dogs, camels, through which it reaches man - the ultimate owner. Contamination can be permitted when using raw bacon. Eggs entering the human body is very dangerous, as it becomes an intermediate owner, the Finnish period in which it occurs often leads to dangerous diseases and death.
Worms cause tapeworms, helminths. If there are a lot of these parasites, they clog the intestinal tract, so the patient needs urgent surgery. They can penetrate the intestinal wall, enter the lymphatic vessels and enter internal organs. Complications of the disease lead to damage to the subcutaneous tissue, muscle, skin, spinal cord, brain, bones, and internal organs. The most important thing is to practice prevention, careful preparation of meat before eating. A person must adhere to personal hygiene, prevention of helminthiasis.
