Unfortunately, people learn what trichinosis is, having already faced the disease. If they had been interested in parasitic diseases in advance, they could possibly have prevented its development. That is why scientific and educational work with the population that lives in unfavorable sanitary and environmental conditions is of such great importance. Theoretically savvy, which means armed and ready for possible contact with parasites.

What is Trichinosis?

Trichinosis is a massive defeat of the human body by parasites called Trichinella. This is a filamentous helminth of microscopic size. As a rule, a sexually mature female does not exceed 5 mm. The mature helminth parasitizes the small intestine, but its larvae can be found in all muscles except the heart.

Once in the human body, Trichinella parasitizes there for 56 days, giving birth to 20,000 live larvae during this time. The larvae enter the lymphatic and blood vessels and are carried throughout the host's body. 18-20 days after infection, the parasite lengthens to 0.8 mm and begins to coagulate.

Trichinosis symptoms in humans are pronounced, it all starts with temperature jumps, which gradually develops into a fever. Symptoms of parasitic invasion may differ, depending on the stage of trichinosis, treatment must be carried out already at the first alarm bells.

At the stage of invasion, the parasite has not yet had time to fully attach to the intestinal walls and release toxic substances, respectively, the signs of a pathological condition will be blurred. In the first few days after infection, a person can observe:

  • violation of appetite;
  • nausea;
  • loose stools;
  • pain in the navel;
  • bloating and colic.

The second phase of the development of the disease is called dissemination. At this stage of development, the signs of trichinosis in humans will be more intense, the patient feels:

  • swelling of the face, especially the eyelids;
  • muscle pain;
  • rash on the skin and severe itching;
  • decreased performance;
  • vomiting;
  • irritation;
  • sleep disturbance;
  • convulsions at night;
  • pallor of the skin.

At the stage of encapsulation, the intensity of the symptoms decreases, and the disease becomes chronic. Symptoms of trichinosis at the stage of encapsulation will give depending on the organ that is struck. With kidney damage, nephritis develops, liver - hepatitis, lungs - pneumonia. The whole complexity of the treatment of trichinosis in humans lies in the fact that doctors rarely assume that the parasite is affected by these organs, and they treat the above diseases with anti-inflammatory drugs to which helminths are not sensitive.

Trichinosis infection methods


The source of infection is wild animals, they are the primary host of the parasite. Together with feces, Trichinella spreads to forest berries, mushrooms, gets into the water - infecting fish. Contacting the grass and directly with feces, pets become infected and, accordingly, transmit the larvae to people. A person can catch Trichinella by eating infected berries and drinking water.

Trichinosis in humans can occur after eating meat from an infected animal. It is in meat that most of all sexually mature parasites are invisible to the human eye, and their larvae. It will be interesting to know that infections are usually of a group nature. All people can become infected, regardless of the degree of immunity that they ate infected meat. The seasonal nature of group parasitic outbreaks of the disease has been established. They are due to the spring slaughter of cattle, pigs, and the preparation of meat products. Trichinella photos, which are presented in our article, parasitize the bodies of pigs, bears, foxes, wild boars, dogs, cats, as well as rodents, fish and marine mammals.

Trichinosis diagnosis, which is the key to successful treatment, requires an integrated approach to therapy. The sooner the doctor identifies the parasite and makes a diagnosis, the more favorable the outcome will be. In the presence of the above manifestations of the disease, the doctor may prescribe the patient to undergo a series of laboratory tests of blood and feces. If the presence of the parasite is confirmed, the doctor usually prescribes the following drugs:

  • Mebendazole;
  • Vermox;
  • Albendazole;
  • Thiabendazole.

The above drugs have a high level of toxicity, so you cannot prescribe them yourself or deviate from the dosage indicated by your doctor.

Treatment for trichinosis will also include symptomatic therapy. Occasionally, patients are prescribed anti-inflammatory medications such as Volaren, Ortofen and Diclofenac. In the presence of a stable temperature, Paracetamol, Aspirin and Ibuprofen tablets are shown. Trichinosis does not respond to antibiotics, therefore, the appointment of these medicines is not advisable. Be sure to use funds that increase the body's immune forces, and vitamins. Sometimes sorbents are prescribed, which help to remove toxic waste products of parasites.

Trichinosis what it is, now you know, respectively, everyone understands that it is better to avoid infection by observing preventive measures. Taking into account the severity of the disease, trichinosis prevention is the responsibility of the Consumer Surveillance Service, since massive outbreaks of the disease and the spread of the parasite to large areas can occur. The first signs and symptoms of the disease should be carefully controlled in a hospital setting. Doctors are required to warn relevant government agencies of outbreaks of trichinosis, and infected meat and fish must be disposed of.

To prevent the development of this parasitic disease, you can properly subject the products to heat treatment. Pig and cattle meat must be cooked at a temperature of at least 75 degrees for 30 minutes. Freezing is also an excellent method of killing the parasite. If the meat is frozen to -15 degrees for 3 days, then all pathogenic microorganisms, and Trichinella in particular, die. There are preventive measures that directly concern farmers, they should not allow pigs to eat dead rats and rodents.

Probably the simplest measure of disease prevention is buying meat and fish at proven points of sale. Infected meat of a pig or game can contain up to 200 larvae per gram, this is simply an amazing amount, destructive to humans. At the same time, a piece of meat will absolutely not differ in consistency, color and smell from good meat of healthy animals. The larvae can only be detected under a microscope in the appropriate laboratories. That is why, when buying, make sure that the carcass is labeled from the laboratory. This indicates that the meat has been inspected and is safe for humans.
