There are about 250 species of worms that pose a health threat to adults.As a result of infection with parasitic worms, the disease helminthiasis develops.The vital activity of worms in internal organs can lead to severe allergies, hypovitaminosis and pancreatitis.All age groups of the population are susceptible to infection, but children have a higher infection rate.
Most types of worms are found inside the body, only there they lay eggs and die after a certain period of time.
Forms of parasitic worms and features of their development.
Depending on the method of spread, the main groups of parasites are distinguished:
- Biological helminths.In the process of going through the entire development cycle, several hosts are replaced.These include tapeworms, nematodes and echinococci.
- Geohelminths.Able to spread without intermediate hosts, but through the soil.A person becomes infected by eating unwashed fruits and vegetables.Main representatives: intestinal worms, whipworms, neckers.
- Helminths transmitted by contact with an infected person.This group includes pinworms and dwarf tapeworms.
There are more than 150 species of helminths recorded in humans.
Parasites also differ in their location in the body:
- tissue affects internal organs and the tissues that make them up;
- Cavities live in the intestinal lumen and absorb nutrients that humans need.
According to their appearance, helminths are divided into 3 groups:
- intestinal worms;
- flatworms;
- trematodes.
Methods of infection with helminths
In most cases, parasites enter the host's body in the following ways:
- The larvae or eggs of worms, along with feces, end up in soil or water, infecting a person by consuming unwashed food or raw liquids.During the summer holidays, the probability of invasion through bodies of water increases.
- Upon contact with a sick person or common objects.This method of propagation is typical for pinworms.At night, the female emerges from the anus and lays eggs.This process causes intense itching, as a result of which eggs remain on the hands and underwear.They are then given to a healthy person.
- Tapeworm infection occurs from eating raw and undercooked meat.Tapeworms of this species infect the muscle tissue of intermediate hosts, including cattle and pigs.
- Insects can carry worm eggs and larvae on their limbs, increasing the area of possible infection.
The life cycle of the vast majority of parasites consists of the release of a large number (millions) of eggs that, upon penetrating the human body, after a while become larvae.
The development of the parasite in the human body can cause acute and chronic forms of the disease.The acute form is characterized by pronounced symptoms and persists for up to two months.Chronic infestation can occur throughout a person's life if left untreated.
The main types of helminths that parasitize humans.
Each form of microorganism is characterized by damage to a specific organ and corresponding symptoms.However, all parasites have in common the way they obtain nutrients: at the expense of the host.In this case, a person's metabolism is disturbed, anemia and other types of diseases develop.
There are different forms of helminths:
- Nematodes are large white nematodes up to 20 cm long.Adults live in the small intestine and larvae can travel through the circulatory system to the lungs.They are classified as geohelminths;Infection occurs through consumption of unwashed vegetables, fruits and water.Parasite eggs also accumulate in the sand.
- Pinworms are small worms that can be seen with the naked eye after defecating.The area of distribution is the lower part of the small intestine.Enterobiasis is formed under the influence of the parasite.The cause of infection is contact with a sick person.It is very common in children under 14 years of age.
- Hades.These include the bovine and porcine tapeworm and the broad tapeworm.They are distinguished by their ability to increase the population at a rapid rate due to hermaphroditism.Its body consists of many parts containing the reproductive system and thousands of eggs.Depending on the type of parasite, different diseases develop.Located in the small intestine, they damage the epithelial mucosa.They accumulate in the intestinal lumen and can cause obstruction.Infection occurs by eating undercooked beef, pork, or fish.
- Whipworm is a hair-like roundworm with a thickened back.Due to its structural characteristics, it penetrates blood vessels and feeds on tissue fluid.Lack of treatment leads to a decrease in the body's resistance to infections and cancer.The source of infection is dirty food.
The insidious thing about helminthiasis is that it successfully disguises itself as other diseases.
The development of the parasite from the egg to the mature individual occurs in three weeks.During this period, symptoms may be absent or mild.If left untreated, intensive reproduction of the worms will cause the disease to become chronic.
Signs of illness due to a helminth infestation.
The main symptoms of worm infection appear as:
- weakness and fatigue;
- pain in the intestines;
- constipation alternating with diarrhea;
- swelling in the face or all over the body;
- inflammation of the lymph nodes, cough and choking;
- skin rashes that cause itching;
- joint pain.
The topic of parasites is unpleasant and terrifying, which is why many myths have arisen about these pests.
The consequences of a worm infestation are often disguised as other diseases.The difference between pathologies lies in the specific signs of alterations in the functioning of the body.Depending on the type of helminths there may be:
- increased salivation, slight increase in temperature, hives due to ascariasis;
- frequent urge to urinate, sleep disturbances, persistent pain in the navel area when infected with pinworms;
- nausea, vomiting, pale skin, hypotension when affected by tapeworms;
- yellowing of the sclera, dizziness, heaviness in the liver area, pain throughout the body in case of trematode infestation.
It is important to detect worms quickly through testing and apply effective treatment.
The symptoms of helminthiasis directly depend on the type of parasite, its location in the body and the intensity of the infection.
Material collection methods to identify intestinal parasites.
The main test to accurately diagnose the presence of worms is stool examination.The material is sent to the laboratory in a sterile container on the day of stool collection.The use of laxatives and contact with urine of the material is unacceptable.Before sending it to the laboratory, the container with feces should be kept in the refrigerator at a temperature of 4 to 5 degrees.
Additionally, the following tests may be prescribed:
- immunological test;
- blood and urine tests;
- scraping of the vagina in women and girls;
- sputum examination in the presence of cough;
- Ultrasound and endoscopy;
- bile analysis.
An enzyme-linked immunosorbent test is an effective way to detect helminths in the body.
A person can become infected with one or more types of helminths.As a rule, the presence of individual individuals in the body is characterized by the absence of symptoms.An increase in the worm population causes serious damage to internal organs, leading to health problems.The symptoms of the disease worsen at night, which also affects resistance to the parasite.
Methods to treat helminthic infestations.
Specialized drugs affect different groups of helminths.The use of medications is possible both in case of infection and for prevention.Medications are prescribed only after identifying the type of worm that has infected the body.
Adult nematodes and pinworms are destroyed with medications containing mebendazole, which blocks the worm's ability to feed and reproduce.
Modern pills for worms are divided into three groups, depending on the sensitivity of the parasites to the drugs.
Whipworms are treated with medications containing mebendazole and albendazole.Iron supplements are necessary to eliminate the consequences of rectal prolapse.
The course of treatment is strictly prescribed by the treating doctor.Self-administration of medications is unacceptable due to various contraindications.
Application of traditional medicine.
The most common worm remedy is pumpkin seeds.They are consumed in the morning on an empty stomach, after crushing and adding honey.The recommended dose is about 300 grams in one hour.After taking it, it is necessary to cleanse the stomach with laxatives.
Various decoctions and infusions have proven themselves well:
- tansy;
- yellow gentian;
- sandy immortelle;
- garlic
The use of home remedies for worms in adults is recommended for preventive and therapeutic purposes.
It is recommended to use a decoction of wormwood as an enema.It is possible to use fresh herb juice mixed with alcohol.Carrots and their juice also kill parasites.
Preventive measures against worms and their effectiveness.
Clean hands are the most effective way to protect children and adults from infection with any type of parasite.The concept and rules of personal hygiene must be developed in children from an early age.A healthy lifestyle also helps reduce the likelihood of developing the disease.
Purified or boiled water should be available 24 hours a day to avoid the possibility of drinking contaminated liquid.It is best to wash vegetables and fruits with boiling water.
Caution should be taken when coming into contact with animals.Pets must be treated against various parasites, both external and internal.Don't forget about routine vaccinations for dogs and cats.
Vaccines will minimize the risk of losing a family member to one of the common diseases.
It is possible to use preventive medications prescribed by a doctor.Worm infection can develop into dangerous diseases, so it is important to minimize the risk of worms entering the human body.
