Helminthiasis is a common problem in some categories of the population.Children, as a rule, are parasitized by pinworms, people who often consume fish are diagnosed with diphyllobothriasis, and trichinosis is common among hunters.
The fact that human worms cause the development of many diseases that would seem to have nothing to do with helminthiasis is currently confirmed by a wide variety of studies.In particular, there is a theory that helminthic diseases are associated with the development of oncological processes.
Also, you should be aware that if helminths are present in the body, this does not mean that the patient will have symptoms of such an infection.The signs of their presence can be masked by other disorders of the liver, gallbladder and gastrointestinal tract.As a result, a person can use different means for a long time and not detect the infection.And after selecting the correct anthelmintic treatment regimen for the patient, the disease can be cured.Therefore, asking yourself the questions: "What should I do if I have helminths, how can I control parasites and will I infect my loved ones?", you should not be afraid to consult a doctor and get all the answers, as well as find out what to do if you have worms.
Read the article below for answers to questions about what worms are, how dangerous these parasites are, and how to avoid getting infected with different types of parasites.We will also talk about what the signs of worm infection are, both general and specific.
How can you get helminth infection?
Helminth eggs can enter the human body in several ways.There are four main methods of infection:
Biohelminthiasis.Worms can be found in raw or undercooked meat, as well as fish.You can get the infection by consuming lard, shish kebab, dried fish, sushi, etc.
Geohelminthiasis.Mature helminth eggs found in soil and water enter the body.They are found in this environment, and because human feces ends up there, as well as animal feces.Infestations also occur when a person comes into contact with animals, for example, constantly cleaning up cat or dog feces, as well as when food is contaminated with fly eggs.
Contact.The most common worms, human pinworms, are transmitted from person to person.In this case, the risk of contracting this disease is higher.
A number of parasites can enter the body when a person is bitten by insects.
When trying to find the answer to the question of what causes worms and how they are transmitted, it should be borne in mind that the main route of infection by parasites is oral-fecal.That is, a person simply swallows worm eggs when eating food or drinking water.In rarer cases, worms appear in humans after bites from infected insects.
Worm infection through the soil
After contact with earth, sand, etc., it is necessary not only to wash your hands very well, but also to clean your nails.It is best for children to cut their nails very short.All vegetables growing in the ground must be washed very thoroughly and, if possible, scalded with boiling water.
Animals and flies
Wikipedia shows that worm eggs can appear in the house and from pets: cats, dogs walking on the street.The risk of infection is high if children play with these animals.Therefore, you need to act immediately if you suspect your cats have worms.You can learn about the symptoms and treatment of infection in animals from your veterinarian or watch the corresponding video online.In this way, any type of worm can appear in the body.Therefore, the answer to the question of whether they are transmitted from dogs to humans and whether it is possible to contract the infection from a dog is clear: yes, it is possible.
Another carrier of helminths are flies.They may initially land on feces and livestock waste, then fly and land on food.As a result, they spread helminth eggs, and people develop helminth diseases after infection.
How are worms transmitted from person to person?
How can you get infected with pinworms and are these parasites transmitted from person to person?The answer to this question is simple: If a female pinworm crawls out of the intestine through the rectum of a child's butt at night, she can lay a large number of eggs near the anus – up to 5,000 eggs.As a result, severe itching occurs, the child itches, and eggs fall on his hands.Then the eggs fall from the child's hands onto clothes, bedding and other objects that the child touches.It is clear how worms are transmitted further: the eggs infect other children and adults, after which small white pinworms multiply in the body.This is why it is very important to wash your hands before eating and after returning home from public places.
Infection through water
Many parasite eggs are found in open water bodies, as well as in well water.That is why people using such water must use a special bactericidal filter.It is also very important to boil the water you drink and eat the dishes prepared with it.It is very dangerous to swallow water from tanks.
When talking about what a helminth infestation is, it should be borne in mind that this is a disease that mainly affects children, as they are very susceptible to helminthiasis.The fact is that protective barriers are not yet developed in children to the same extent as in adults;their stomach acid is lower.
Also, signs of the presence of worms in a child appear very often due to the fact that young children, in the process of exploring the world, taste everything that comes to hand.Therefore, parents very often notice symptoms of helminth infestation in children, in particular itching in the anus, poor appetite, cough in infected children, etc.But it is still impossible to teach a child to strictly follow the rules of hygiene in the first years of life.Therefore, at this time, the risk of infection is high for all family members.
Speaking about worms - what it is and how to treat this disease, you should remember that worms do not reproduce in the human body.Worms in the human body die within a certain period of time.For example, pinworms live for several weeks, roundworms for about a year.The eggs that adult parasites lay in the body definitely come out of the intestine - either when the baby's feces or poop comes out, or they end up on the skin near the anus, as happens with pinworms.When the eggs are outside the human body, they mature in the external environment, after which they enter the human body again and parasitize it again.
Since worms do not reproduce in the body, a large number of helminths is observed only if reinfection occurs, if the eggs enter the body again through the mouth.
As a result, if reinfection does not occur, pinworms living in the body die in about 4 weeks.And if you carefully follow all preventive measures, you can eliminate the presence of worms without treatment.However, in the case of children, compliance with all these rules is a very difficult task.
Signs of helminths
When infected with parasites, some first symptoms of worms appear in humans.You can find out in detail from a specialist what symptoms of worms appear if you are infected.But some signs of worms in humans can easily be noticed independently.
So, the most obvious sign that a parasitic infection has occurred is the presence of sudden weight loss.The patient's skin also becomes pale: this is how anemia manifests itself.Signs of helminth infestation also appear in appearance: the person seems exhausted and his level of fatigue may increase.
Helminths cause itching in the anus if the intestine is infected.However, they can also parasitize other organs: lungs, liver, bladder and even arms or legs, etc.
However, all of the above symptoms of parasites in the human body are only the first general signs of infection, which develop with extensive damage to the body by worms and allow you to recognize that something is wrong with your health.There are other more specific symptoms of helminth infestation in adults.The patient may perceive them as a manifestation of other diseases.At the same time, it can cure such diseases for a long time, of course, unsuccessfully.This lasts until the exact cause of such symptoms is determined - helminthiasis.You can see more details about it in the corresponding videos on the Internet.
What symptoms of worms can occur in an adult and a child?
Digestive disorders
If the parasites are located in the intestine and not in other organs, the main symptoms in adults and children are dysfunction of the digestive system.A person may be bothered by constant diarrhea or constipation, periodic nausea, vomiting, stomach pain, pain in the right hypochondrium, near the navel and intestinal disorders.If you have intestinal parasites, you are often worried about flatulence.
All of the above symptoms can be strong or weak, long-lasting or intermittent.It all depends on the severity of the infection.There are types of helminths that produce hormone-like substances, under the influence of which constant diarrhea develops.If large worms become large (like tapeworms), they block the intestines and cause constipation.
General malaise, nervous system disorders
Worms live and secrete very large amounts of toxic substances, regardless of whether parasites live in the blood, liver, lungs of humans.The more massive the infection, the more pronounced the signs of intoxication of the body, which negatively affects the nervous system.
As a result, headache, dizziness and nausea develop.Some people mistake these signs for the development of a migraine and, as a result, take painkillers.
Sometimes, when infected with parasites, the temperature rises and joint pain occurs.In addition, helminth infections cause a deficiency of vitamins and nutrients in the body.This phenomenon, as well as depression of the nervous system, leads to the manifestation of chronic fatigue syndrome.The patient feels tired, drowsy and a feeling of weakness in the body.If we are talking about a child, he is capricious and constantly nervous.Young children have difficulty sleeping and cry or scream at night.School-age children may have difficulty learning due to inattention and tiredness.
Allergies and skin manifestations
Signs of helminths Worms cause deterioration of the skin.The toxins that worms infect the body negatively affect its general condition and can cause a variety of reactions on the skin.Skin rashes appear as a result of the release of histamine from mast cells and the accumulation of the liquid part of the blood in the tissues with lifting of the epidermis.
These same reasons lead to the development of allergic reactions.In particular, itching, red spots, pimples, hives, but also dry cough, allergic rhinitis and manifestations of bronchial asthma may appear.Also, in case of infection, nails may peel, hair may become brittle, and cracks may appear on the heels.
Deterioration of immunity and infectious diseases
As worms feed on the body, they release toxic waste products.The toxic effect, the decrease in vitamins and minerals in the body leads to the fact that the immunity of the infected person deteriorates significantly.As a result, the state of health of chronic diseases also worsens, and inflammatory processes in the nasopharynx - sinusitis, stomatitis - begin to worry.Vulvovaginitis and bacterial vaginosis are possible in women and girls.There is evidence that with prolonged infection with pinworms, inflammation of the appendages can develop.In this case it is very important to promptly detect its presence.Parasites in the liver also cause bad breath and a persistent bad taste.
There is also an opinion that worms in humans provoke the appearance of snoring and night grinding of teeth.But at the moment this relationship has not been proven.
Where do parasites live in the human body?
The types of parasites in the human body are determined depending on where exactly they live in the body.How to determine the presence and how to remove parasites from the body depends on their type.
Translucent
These worms mainly inhabit the intestine, living in its various parts.Hookworms, roundworms, broad tapeworms, and other tapeworms are located in the small intestine.The small intestine is home to dwarf tapeworms and pinworms, while the large intestine is home to whipworms.There are about a hundred species of cavity parasites.Photos and images can be found online.
Tissue
These types of worms in humans do not live in the intestines, but in organs and tissues.There are varieties that live in the brain (cysticercosis), liver (echinococcosis), lungs (paragonimiasis), muscles, lymphatic vessels (filariasis), as well as other helminths.
You can find out what other worms a person has from a specialist.
Nematodes are a species that belongs to both luminal and tissue parasites, since in the first stage of their development they can move through the blood and affect any organ.How to get rid of roundworms will be explained by the doctor, who will prescribe a treatment regimen for infection with such parasites.
You can find out what worms look like in humans by looking at a picture of the corresponding type of parasite.Special literature shows how worm eggs appear.
Signs of infection depending on the type
How worms manifest themselves and why they are dangerous depends on the type of parasite, where exactly they live in the body, and also on the intensity of the infection.Signs of infestation in humans can be detected within a few days.For example, if roundworms appear, health worsens within 2-3 days.When infected with other types of helminths, the first signs are observed in the patient after 2-3 weeks.The incubation period for heartworm varies from 6 to 18 months.
Intestinal worms are dangerous from the point of view that if there is a single individual in the intestine, it is impossible to understand that a person is infected, since there are no signs.Some symptoms may only be worrisome if the worms are long (roundworms, broad tapeworm, etc.) or if a massive infection has occurred.Almost all helminthiasis cause headache, fatigue, dizziness and irritability.
What types of worms are there, what are they called and what do they look like?
Pinworms (enterobiasis) - the presence of this type of helminths can be determined by the manifestation of the main symptoms, as well as the manifestation of itching in the anus, which becomes more intense at night.If there are only a few pinworms in the body, the itching may occur for a few days, then disappear and return after a few weeks.With a severe infestation, itching may be felt constantly.
Roundworms: What are the signs of ascariasis depends on the stage of development of these parasites.In the phase in which the larvae migrate to the heart, lungs and other organs, weakness, low-grade fever and a cough that produces sputum, sometimes with pus and blood, occur.If you take an x-ray of the lungs at this time, it will show volatile infiltrates, which will then disappear.Allergic reactions develop, a blood test shows a large percentage of eosinophils.If the infestation is severe, bronchitis, pneumonia and asthma attacks are likely to develop.People often wonder if there can be a cough when they are infected?Indeed, it is possible.You may also experience a sore throat.The signs of the second phase are associated with digestive disorders.Nematodes produce substances that neutralize pepsin and trypsin, the human digestive enzymes.As a result, proteins are not digested and the patient loses a lot of weight.Ascariasis sometimes causes complications: pancreatitis, obstructive jaundice, intestinal obstruction, appendicitis.
Ankylostomiasis, schistosomiasis, diphyllobothriasis, trichocephalosis - with such lesions anemia and vitamin deficiencies develop.After all, toxins secreted by helminths of these varieties significantly worsen the intestinal microflora, provoking the development of dysbacteriosis.
Opisthorchiasis, fascioliasis, clonorchiasis are liver parasites.The consequences of the invasion are jaundice syndrome, enlargement of the liver, spleen, pancreatitis, cholecystocholangitis, neurological disorders, pathologies of the digestive system.
Trichinosis: With such a lesion, the most common symptoms are muscle pain, swelling of the eyelids, swelling of the face and fever.
Strongyloidosis is caused by roundworms, the symptoms are very different.Signs of dyspepsia, allergies, biliary tract dysfunction, etc. may appear.
Urogenital schistosomiasis is caused by flatworms and manifests as diuretic disorders.At the end of urination, blood is found in the urine.In men it can lead to pathological lesions of the prostate and pathologies of the seminal vesicles.In women it causes consequences in the form of vaginal bleeding and genital lesions.Fibrosis can appear in the bladder.
Cestodosis is caused by tapeworms.These are bovine tapeworm, sheep brain worm, echinococcus, tapeworm, etc.Signs of the disease are severe weight loss, weakness, and gastrointestinal dysfunction.
How to determine the presence of worms in a person?
If you are worried about some symptoms that indicate an infection, a person is naturally concerned about how to tell if you have helminths.Of course, it is possible to say for sure whether there is an infection or not only after visiting a doctor and carrying out all the necessary tests.But there are other methods suitable for those who are interested in finding out that they have worms.To do this, you need to carefully monitor your health and pay attention to the changes that occur in the body.After all, the presence of some pronounced symptoms answers the question of how to understand that you have worms.
Prevention of worm infection
To prevent infection, it is necessary to clearly understand what the causes of the invasion are, what helminthiasis is and what worms are.It is important to take all preventive measures that significantly reduce the likelihood of infection.
- It is necessary to thoroughly wash fruits and vegetables and pour boiling water over them.
- It is important to fight flies, cockroaches, mosquitoes - to track where they come from and destroy them.
- Cook meat and fish for at least 40-60 minutes.
- You need to use only your own hygiene items: a towel, a comb (to avoid transmission of lice), etc.
- It is important to teach your child to immediately go and wash his hands with soap before eating, as well as after any contact with animals.
- If there are animals in the house, large and small, it is necessary to constantly give them means to prevent worms.To find out which ones you need to contact your vet.
- It is important that younger children only play with clean toys;they should also wash a dropped pacifier or pacifier immediately.
- Children should be weaned from bad habits: sucking fingers, biting nails, putting different things in their mouths.
- The child should have clean and short nails.
- To prevent reinfection with pinworms, the child should wear thick panties at night, which prevent the spread of parasites and eggs throughout the bed.
- It is important to iron your baby's clothes after washing.
- In the morning you need to change your panties and wash your baby thoroughly.
