Helminthiasis is a common problem among certain categories of the population.Children, as a rule, are parasitized by pinworms, people who often consume fish are diagnosed with diphyllobothriasis, and trichinellosis is common among hunters.
The fact that human worms provoke the development of many diseases that 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.
In addition, you should know that if there are helminths in the body, this does not mean that the patient will show symptoms of such an infection.Signs of their presence can be disguised as other diseases of the liver, gall bladder and gastrointestinal tract.As a result, a person can use various means for a long time and not detect an infection.And once the right anthelmintic treatment regimen is chosen for the patient, the disease can be cured.Therefore, asking yourself the questions: "What should I do if I have helminths, how can I check for 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 a worm infection are, both general and specific.
How can you get infected with helminths?
Helminth eggs can enter the human body in different ways.There are four main ways of infection:
Biohelminthosis.Worms can be found in raw or undercooked meat as well as fish.You can get infected by eating lard, shish kebab, dried fish, sushi, etc.
Geohelminthiasis.Mature eggs of helminths, which are in the soil and water, enter the body.They fall into this environment also because human excrement, as well as animal excrement, also falls there.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 the disease is the highest.
A number of parasites can enter the body when a person is bitten by insects.
When trying to find an 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 with parasites is oral-fecal.That is, a person simply swallows worm eggs when eating food or drinking water.In rarer cases, worms appear in people after being bitten by insects that have been infected.
Worm infestation through the soil
After contact with dirt, sand, etc., you should not only wash your hands very well, but also clean your nails.It is better for children to cut their nails very short.All vegetables that grow in the ground should 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 domestic animals - cats, dogs that walk on the street.There is a high risk of infection if children play with such animals.This is why you should take immediate action if you suspect your cats have worms.You can learn the symptoms and treatment of infection in animals from your veterinarian or watch a related video online.In this way, any kind of worms 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 get infected 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 in and land on food.As a result, they spread helminth eggs and people develop helminthic diseases after infection.
How are worms transmitted from person to person?
How can you get 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 into the baby'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 baby scratches and the eggs fall on his hands.The eggs then fall from the baby's hands onto clothes, bedding and other objects the child touches.It is clear how the worms are transmitted further: the eggs infect other children and adults, after which small white weevils multiply in the body.That is why it is very important to wash your hands before eating and after leaving public places.
Contagion through water
Many parasite eggs are found in open bodies of water as well as in wells.Therefore, people using such water should use a special bactericidal filter.It is also very important to boil the water you drink and eat food prepared from it.It is very dangerous to swallow water from reservoirs.
When we talk about helminth infestation, it should be borne in mind that this is a disease that mainly affects children, since they are very susceptible to helminths.The fact is that in children the protective barriers are not yet developed to the same extent as in adults;their stomach acidity 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 learning about the world, taste everything they come across.That is why parents very often notice symptoms of helminthic infestation in children, in particular itching of the anus, poor appetite, cough in children when they are infected, etc.But it is still impossible to teach the child to strictly follow the rules of hygiene in the first years of his life.Therefore, at this time, the risk of infection is high for all family members.
Speaking of eggworm - 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 over a period of time.For example, pinworms live a few weeks, roundworms about a year.The eggs that the adult parasites lay in the body will certainly come out of the intestines - either when the feces or baby feces come out, or get on the skin near the anus, as happens with pinworms.When the ova are outside the human body, they mature in the external environment, then enter the human body again and parasitize it again.
Since the worms do not reproduce in the body, a large number of helminths is observed only if re-infection occurs, if the eggs again enter the body through the mouth.
Therefore, if re-infection does not occur, pinworms living in the body die in about 4 weeks.And if you carefully follow all preventive measures, you can get rid of the presence of worms without treatment.However, with children, compliance with all these rules is a very difficult task.
Signs of helminths
When infected with parasites in humans, some first symptoms of worms appear.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 be easily 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.Appearance also shows signs of helminthic invasion - the person looks exhausted and the level of fatigue may increase.
Helminths cause itching in the anus if the intestines are infected.However, they can also parasitize other organs – the lungs, liver, bladder and even the arm or leg, etc.
However, all the above symptoms of parasites in the human body are only common first signs of infection, which develop with massive damage to the body by worms and allow to recognize that something is wrong with 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, he can treat such diseases for a long time, of course, without success.This continues until the exact cause of such symptoms is established - helminthiasis.You can see more details about this in the corresponding videos on the Internet.
What symptoms of worms can appear in an adult and a child?
Digestive disorders
If the parasites are localized in the intestines and not in other organs, then the main symptoms in an adult and a child are digestive system dysfunction.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 often worry about flatulence.
All the above symptoms can be strong or weak, long 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 (such as tapeworms), they block the intestines and cause constipation.
General malaise, disorders of the nervous system
Worms live and release very large amounts of toxic substances, regardless of whether the parasites live in the blood, in the liver, in the lungs of the person.The more massive the infection, the more pronounced the signs of intoxication of the body, which negatively affects the nervous system.
As a result, headaches, dizziness and nausea develop.Some people mistake these signs for a migraine and take painkillers as a result.
Sometimes, when infected with parasites, the temperature rises and joint pains appear.In addition, helminth infections provoke a deficiency of vitamins and nutrients in the body.This phenomenon, as well as the depression of the nervous system, leads to the manifestation of chronic fatigue syndrome.The patient feels tired, sleepy, has a feeling of weakness in the body.If we talk about a child, he is capricious and constantly nervous.Young children have trouble sleeping and cry or scream at night.School-age children may struggle to learn due to inattention and fatigue.
Allergies and skin manifestations
Signs of helminths Worms cause skin deterioration.Toxins that worms infect the body negatively affect its general condition and can provoke various skin reactions.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 tissue with lifting of the epidermis.
These same reasons lead to the development of allergic reactions.In particular, itching, red spots, pimples, urticaria, as well as dry cough, allergic rhinitis and manifestations of bronchial asthma may occur.Also, when infected, nails can peel, hair can become brittle, and cracks can appear on the heels.
Deterioration of immunity and infectious diseases
As the worms feed on the body, they release toxic waste products.The toxic effect, the reduction of vitamins and minerals in the body leads to the fact that the immunity of the infected person significantly deteriorates.As a result, the health status of chronic diseases also worsens, and inflammatory processes in the nasopharynx - sinusitis, stomatitis - begin to worry.In women and girls, vulvovaginitis and bacterial vaginosis are possible.There is evidence that inflammation of the appendages may develop with prolonged pinworm infection.In this case, it is very important to detect their presence in time.Liver parasites 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 such a connection has not been proven.
Where do parasites live in the human body?
The types of parasites in the human body are determined by where exactly in the body they live.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 localized in the small intestine.The small intestine is home to tapeworms and pinworms, and the large intestine is home to worms.There are about a hundred species of cavity parasites.Photos and images can be found online.
Cloth
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), in the liver (echinococcosis), lungs (paragonimosis), in the muscles, in the lymphatic vessels (filariasis), as well as other helminths.
You can find out what other worms a person has from a specialist.
Roundworms are a species that belongs to both luminal and tissue parasites, since in the first phase of their development they can move through the blood and affect any organ.Your doctor will tell you how to get rid of roundworms, 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 what worm eggs look like.
Signs of infection depending on the species
How worms manifest and why they are dangerous depends on the type of parasite, exactly where they live in the body, and the intensity of the infection.Signs of infection in humans can be detected within a few days.For example, if roundworms appear, then health deteriorates 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 of filariasis varies from 6 to 18 months.
Intestinal worms are dangerous from the point of view that if there is one individual in the intestine, then it is impossible to understand that a person is infected, since there are no signs.Some symptoms may only be alarming if the worms are long (ascarids, broad tapeworm, etc.) or if a massive infection has occurred.Almost all helminth infections cause headache, fatigue, dizziness and irritability.
What types of worms are there, what are they called and what do they look like?
Pinworms (enterobiosis) - the presence of this type of helminths can be determined by the manifestation of the main symptoms, as well as by the manifestation of itching in the anus, which becomes more intense at night.If there are only a small number of pinworms in the body, itching may appear for a few days, then disappear and reappear after a few weeks.In case of severe infection, itching may be felt constantly.
Roundworms - what are the signs of ascariasis depends on the phase of development of these parasites.In the phase when the larvae migrate to the heart, lungs and other organs, there is weakness, low-grade fever and a cough that produces sputum, sometimes with pus and blood.If you take an x-ray of the lungs at this time, it will show volatile infiltrates, which later disappear.Allergic reactions develop, a blood test shows a high percentage of eosinophils.If the infestation is severe, bronchitis, pneumonia and asthmatic attacks are likely to develop.People often wonder if they can have a cough when they are infected?It is indeed possible.You may also experience a sore throat.The signs of the second phase are related to digestive disorders.Roundworms 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.
Ankylostomosis, schistosomiasis, diphyllobothriasis, trichocephalosis - anemia and vitamin deficiency develop in such lesions.After all, the toxins that helminths secrete from these varieties significantly worsen the intestinal microflora, provoking the development of dysbacteriosis.
Opisthorchiasis, fascioliasis, clonorchiasis are liver parasites.The consequences of the invasion are icteric syndrome, enlarged liver, spleen, pancreatitis, cholecystocholangitis, neurological disorders, pathologies of the digestive system.
Trichinellosis - with such a lesion, the most common symptoms are muscle pain, swelling of the eyelids, swelling of the face and fever.
Strongyloidiasis is caused by roundworms, the symptoms are very diverse.Signs of dyspepsia, allergies, bile duct dysfunction, etc. may appear.
Urogenital schistosomiasis is caused by flatworms and manifests as diuretic disorders.At the end of urination, blood is detected in the urine.In men, it can lead to pathological lesions of the prostate and pathology of the seminal vesicles.In women, it causes consequences in the form of vaginal bleeding and genital lesions.Fibrosis may occur in the bladder.
Cestodiasis is caused by a tapeworm.These are beef tapeworm, sheep tapeworm, 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 concerned about certain symptoms indicating an infection, one is naturally concerned about how to know 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 conducting all the necessary tests.But there are other methods that are suitable for those who are interested in how to find out that you have worms.To do this, you need to carefully monitor your health and pay attention to the changes occurring in the body.After all, the presence of some pronounced symptoms answers the question of how to know that you have worms.
Prevention of worm infection
To prevent infection, you need to clearly understand what are the causes of the invasion, what is helminthiasis and what are the worms.It is important to take all preventive measures, which significantly reduces the likelihood of infection.
- You need to wash the fruits and vegetables well and cover them with boiling water.
- It is important to fight flies, cockroaches, mosquitoes - to trace them where they come from and destroy them.
- Cook meat and fish for at least 40-60 minutes.
- It is necessary to use only your own hygiene items - a towel, a comb (to prevent the transmission of lice), etc.
- It is important to teach your child to immediately go and wash their hands with soap before eating and after any contact with animals.
- If there are animals in the house, big and small, you should constantly give them means to prevent worms.To find out which ones, you should contact your veterinarian.
- It is important that the little ones only play with clean toys;they should also wash a dropped pacifier or pacifier immediately.
- Children should be weaned from harmful habits - sucking fingers, biting nails, putting various things in the mouth.
- The baby should have clean and short nails.
- To prevent re-infection with pinworms, the baby should wear thick panties at night, which prevents the spread of parasites and eggs in the bed.
- It is important to iron baby clothes after washing.
- In the morning you should change your panties and wash your baby thoroughly.
