Contagious helminthiases are helminthiases, eggs and larvae of which are capable of invasion without prior development in the external environment or in the body of an intermediate host.

The incidence of helminthiasis was known in ancient times. To date, more than 400 species of parasites that cause pathology have been officially registered. Medical research has shown that infection with helminthiases is the most common disease in the human body. In the third world countries, polyinvasion occurs en masse, which causes the development of tropical and mixed helminths (when two or more types of parasites are in the body of one patient).

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

Types of human helminthiasis

The causative agents are divided into three types: trematodes, cestodes and nematodes, less often - worms and annelids. Helminths are mainly fixed in the intestines, but they can also affect other organs: liver, muscles, bile ducts, brain, and visual apparatus. By mechanically damaging the internal organs, they poison the body with metabolic and decay products. Multicellular organisms weaken the immune system, making the host more vulnerable to viral and bacterial infections.

Tapeworms (trematodes) cause diseases - trematodes. Some species become infected after eating raw fish, wild plants, water from stagnant sources. The classification of flukes is divided depending on the organ of location in the body.

Tape worms (cestodes)

Worms of the cestode class cause the following types of helminthiasis - cestodes. Subdivided into tapeworms and tapeworms. About 3 thousand species of parasites of this category are known. In most cases, the course of the disease is severe and can be fatal.

The most common group among parasites are nematodes. There are about 24 thousand known species. Pathogens enter the human body with dirty water, food, after an insect bite, through the skin. The cause of the occurrence may be a banal lack of personal hygiene.

According to the biological and epidemiological indicators, helminthiases are divided into types:

  • biohelminthiasis;
  • geohelminthiasis;
  • contact helminthiasis.

If intestinal helminthiasis is a frequent occurrence, then the development of parasites in the eyes is rare. Helminthiasis of the eye develops by the entry of worms into the body, which can penetrate into any human organ.

Signs

The impact of worms on the body occurs for a long time: from two weeks to several years. The complex of actions of parasites goes through several stages. The main symptoms of the appearance of worms in the body:

  • constipation / diarrhea;
  • gas formation, bloating;
  • poor sleep;
  • allergy.

In case of untimely treatment, acute helminthiasis flows into the chronic stage. In this case, there are: indigestion, nervous system, joint and muscle pain, anemia. Sometimes organ damage by parasites leads to serious consequences. With any suspicion of their appearance, you must consult a doctor.

Why are contagious helminthiases dangerous? Complications and consequences

Modern medicine allows you to detect the disease in time and cure it. Therefore, serious consequences were recorded in rare cases. The vital activity of helminths, depending on the species, leads to the following consequences:

  • obstruction of the bronchi or intestines;
  • allergic rash;
  • predisposition to poisoning;
  • the development of anemia;
  • deterioration of health;
  • lowering the percentage of hydrochloric acid in gastric juice.

Helminthic invasion can provoke weight loss, the acquisition of a pale skin, itching in the anal passage. Complications depend on the type of parasite and the degree of infection. The appearance of helminths in children and during pregnancy is especially dangerous.

Helminthiasis in children

Symptoms of the development of the disease in children are similar to infectious and non-infectious diseases, which complicate diagnosis. Detection of helminthiasis in small patients occurs in the laboratory (delivery of tests). Outbreaks of infection are observed in the spring and summer.

The age of children who are especially susceptible to the disease is from one to 14 years. Unfortunately, the development of helminthiasis is also observed in infants. The larvae are able to enter the body of the crumbs through the mother during pregnancy, household members or animals. Infection through insects is possible. This is how transmissible helminthiases are transferred.

The first signs of infection in a child appear 2-3 days after contact with a carrier of the infection. The phase of the disease is similar to the signs of ARVI:

  • malaise;
  • loss of appetite;
  • cough;
  • temperature.

Perhaps the appearance of urticaria, rash on the limbs, flatulence, nausea. Prolonged invasion in a child can lead to side infectious processes: stomatitis, purulent diseases.

The high incidence rate among children is due to the typical non-observance of personal hygiene rules. More than three hundred types of helminths are known that develop in the child's body. Divided into intestinal and extraintestinal helminthiasis. In the first case, parasites develop in the intestines, in the second, in other organs. Infection in children occurs mainly with nematodes. A common causative agent of childhood helminthiasis is ascaris. Larval migration occurs through dirty fruits and water, causing ascariasis. Other types of helminths rarely enter the child's body.

Treatment

The basis of the fight against any helminthiasis is a specific treatment. The most commonly used are the following highly active and at the same time low-toxic drugs:

  • Levamisole (more often - with ascariasis);
  • Albendazole (trichinosis, strongyloidosis, ankylostomiasis, trichocephalosis, ascariasis and enterobiasis);
  • Mebendazole (trichinosis, ascariasis, enterobiasis, trichocephalosis and ankylostomiasis);
  • Pirantel (enterobiasis, ascariasis);
  • Medamin (strongyloidosis, ascariasis, enterobiasis, trichocephalosis and ankylostomiasis);
  • Praziquantel (opisthorchiasis, clonorchiasis, paragonimiasis, schistosomiasis, diphyllobothriasis, teniosis);
  • Diethylcarbamazine (filariasis).

The frequency of taking the drug and its dosage are different for different helminthiases and also depend on the age or body weight of the patient.

In parallel with the therapeutic measures indicated above, symptomatic treatment is carried out, the purpose of which is to eliminate the symptoms caused by the pathological effect of the helminth on the infected body.

The basis for the primary prevention of any type of helminthiasis (i.e., prevention of infection) is the formation of both a child and an adult, a healthy lifestyle, including the social well-being of the family, the level of culture of all its members, material security, etc. Important the moment in the struggle is the use of only high-quality, non-parasitic water in everyday life.

To prevent the spread of infection from an infected person to all family members, you can use individual towels, dishes, personal hygiene items and other accessories for everyday use.

In the spring-summer period, one should not forget about the possibility of infection with helminths by eating dirty vegetables, fruits, berries, as well as through soil and water. The risk of this decreases significantly if the rules of personal hygiene are followed and the fruit is thoroughly washed before use.

The most important preventive measure is sufficient heat treatment of meat and fish products. Raw fish (such as sushi) should not be eaten.

Prevention can be carried out through the use of medication.

Indications:

  • regular contact with pets;
  • finding children in children's groups;
  • contact with the ground;
  • hobby for fishing or hunting;
  • frequent travel to exotic countries.

Medication prophylaxis is required for the whole family 2 times a year (for example, in spring and autumn). Most often, for this purpose, the drug Albendazole is used, which is prescribed according to the scheme: for children over 2 years old and for adults 400 mg (1 tablet or 10 ml of suspension) of the drug once a day after meals for 3 days.
