Guinea worm

6. When a person swims or bathes in ponds with unfiltered water, he can swallow a water flea. These fleas love polluted lakes and ponds, where they sit and wait for their prey. When they enter the stomach, the gastric juice dissolves the flea, but the guinea worm that was inside the flea (guinea worm) passes on. A year later, the worm already reaches a length of 60-90 cm. The human body becomes small for it, and it tries to get out of it to the surface. The body begins to burn, there is a desire to plunge into cold water to get rid of burning and pain. But that’s what the worm needs! It releases thousands of its larvae into the water, but remains in the body.

Common Vandellia - vampire fish

7. Both parents and government officials always remind people that peeing in a river, lake, or swimming pool is prohibited. Now, for sure, no one will do this after reading about the ordinary vandellia. This is a very small fish that lives in the Amazon and enters the bladder during urination. In the body, it feeds on blood and flesh, causing severe pain.

Ascaris

8. Ascaris, an annelid worm, can grow up to 30 cm in length in the human body. It is easy to become infected in rural areas. Her residence inside is not accompanied by any symptoms until the number of worms reaches a maximum. If this happens, then you will suffer from headaches, fever, nausea, diarrhea, etc. In general, roundworms affect children more often than adults, since they wash their hands less often.

Scabies itching

10. The tapeworm is the most terrible parasite, so to speak. It mainly resides in the human brain and lives for 20 years. During this period, symptoms arise that are so widespread that it is extremely difficult to associate them with the vital activity of the parasite. When it grows up, it seeks to kill its owner. You can become infected with the parasite by drinking contaminated water and meat.

  • presence of pain in the lower abdomen, in the navel area;
  • increased appetite or lack thereof;
  • irritability;
  • sleep disturbance;
  • grinding of teeth at night;
  • itching in the anal area;
  • bloating;
  • intestinal dysbiosis;
  • low hemoglobin.

The disease spreads quickly among children. It is much less common in adults. Treatment is carried out with medications and folk remedies.

Ascaris and ascariasis

Infection with this type of helminth occurs quite quickly. Initially, the larva penetrates the bloodstream through the intestinal walls. It spreads throughout the body. It concentrates in the liver, moves to the heart, and stops in the lungs. This migration route takes approximately 2 weeks. The larva in the lung tissue provokes fever, severe cough, inflammation, pneumonia with a large amount of sputum. When a patient swallows sputum, the larva appears again in the intestine and there it continues to develop until adult.

A female roundworm lays up to 240 eggs per day. Together with feces, they leave the body and return to the soil. It takes several months for an adult roundworm to develop. The female's body reaches a length of 40 cm. The body color is reddish. Lives for about 1 year, dies and is excreted in the feces. The body color becomes gray. A photo of the worms is shown below.

In general, helminthiasis is a dangerous disease that can affect various internal organs. Especially the liver, heart, gallbladder, small intestine. The symptoms of the disease depend on the location. The existence of an adult worm in the lungs can lead to death. Treatment is prescribed by a doctor. Folk remedies should be taken after consultation with a specialist.

Toxocara and toxacorosis

Treatment is aimed at removing worms from the body and restoring protective functions.

Hookworm (hookhead) and hookworm

The hookworm or torticollis is similar in appearance to other worms. But it has one peculiarity - its head with teeth turned on its back. You can see it clearly in the photo below. Body length is about 18 mm. With its sharp jaw, the worm gnaws through the intestinal walls. At the site of the bites, bleeding wounds form that do not heal for a long time. With a significant infection with worms, a person loses about 1 liter of blood per day. Which can lead to anemia with all the consequences. In addition, this type of worm affects the heart, gall bladder, and bone marrow. Hence the washed away symptoms.

The main symptom of the disease is low hemoglobin. In general, symptoms of the disease include:

  • vomiting;
  • nausea;
  • skin rashes;
  • dizziness;
  • dysbacteriosis;
  • inflammatory processes in the pelvic organs;
  • digestive problems;
  • menstrual irregularities;
  • insomnia;
  • headache;
  • constant weakness;
  • cough;
  • impotence.

Broad tapeworm and diphyllobothriasis

The body length of the wide tapeworm reaches 10 m. The photo is presented below. In the human body it exists in a twisted form. IN environment gets in the patient's feces. However, further development of the egg occurs only in reservoirs. After a few days, the larva is swallowed by a mollusk. There it develops for several days, leaves the body of the first host, and floats in the water. It is swallowed by a predatory fish, where the worm continues to develop.

The second host, the fish, becomes the cause of human infection. Main symptoms of the disease:

  1. abdominal pain;
  2. increased salivation;
  3. loss of appetite - sometimes absent, sometimes increased;
  4. pain while eating;
  5. signs of anemia;
  6. enlarged spleen;
  7. sleep disturbance;
  8. irritability.

A helminth capable of completely disrupting activity digestive system. Lives in the body for about a year. Treatment consists of expelling the worm from the body, with further restoration of all vital functions.

Bovine, pork tapeworm and taeniarinhoz disease

  • skin rashes;
  • bowel dysfunction;
  • intestinal problems;
  • changeable appetite;
  • decrease in hemoglobin;
  • weakening of the body's protective functions;
  • indigestion;
  • developmental delay;
  • nervous pathologies.

The symptoms of helminthiasis are similar. Diagnosing the disease takes a lot of time. You can avoid this terrible disease by following the rules of hygiene and quality food preparation.

Further, when the egg enters the intestine, a larva emerges from it. The larva can remain in the intestine or penetrate through its walls into the blood. It can migrate through the blood vessels throughout the body until it finds a “suitable” organ. There it settles (with the help of hooks or suction cups it clings to the walls of the organ) and begins to form a bubble or pupa. So the larvae can live for years in the body. Adults will emerge from the pupa or bladder and the cycle will repeat.

When a person is an “intermediate” link, as a rule, there is a special danger internal organs with good “supply”: heart, liver, brain. The larva does not grow into a monster several meters long, like an adult. In the human body they form cocoons or bubbles. In other words, a tumor-like structure is formed, which gradually compresses the blood vessels of the organ, depriving it of nutrition, and also preventing its normal functioning.

Symptoms indicating the presence of the disease

In some cases this may manifest itself as allergic reactions on the skin.

Diagnostic measures

The first thing that is done is stool and blood tests:

Therapeutic measures

In the case when a person is an intermediate carrier and a tumor-like structure is formed in his body, which contains quite a lot of underdeveloped adult individuals “waiting in the wings,” surgical methods are almost always used. This is due to the fact that the shell of such forms is quite strong, and its destruction threatens subsequent infection of the body. Therefore, this formation is simply removed as a tumor.
