A large number of different advertised medications have currently appeared on various websites that are supposed to help against parasites or helminth infestations, among other things.In fact, the vast majority of these advertisements are fake and a complete scam.Medicines for helminthiasis or diseases caused by parasites must be prescribed by doctors on the basis of a precisely established diagnosis.Taking medication to prevent parasites is nothing more than cheating.Furthermore, there is no diagnosis of “parasites”.
Parasites include insects such as lice, fleas and scabies mites.Parasites are also protozoa, for example dysentery amoeba.A large number of parasites are worms or helminths.Helminths are divided into roundworms, flatworms and tapeworms.An example of a nematode roundworm parasitic infestation is enterobiasis or pinworm transmission.Flatworms (trematodes) are cat worms that cause opisthorchiasis.Tapeworms include bovine and pork tapeworms, the causative agents of teniarynchosis and taeniasis, as well as broadband worms, whose helminthic infestation is called diphyllobothriasis.
On all the sites promoting miracle cures for parasites, you will not find a single disease, not a single diagnosis and not a single name of a specific parasite.However, all of these sites contain monstrous, shameless and aggressive advertising.Here are some signs that such websites should be closed and avoided immediately:
- extremely bright appearance of the site itself;
- Close-ups of drug packaging;
- Mention of certain “secret military” or “space” developments that only recently became known to the general public and entered production, this “nutritional supplement” being originally developed for “special service contingents in tropical countries,” and so on;
- the presence of famous names of professors, their photos, as well as photos of various documents with seals allegedly proving the effectiveness and authenticity of the drug.When searching for these doctors and institutions, as well as carefully examining the seals and document forms, it turns out that these institutions and regulatory organizations simply do not exist and the names are “fake”;
- the presence of eye-catching banners with discounts that expire literally in a few hours and with a countdown;
- an express request to click on a specific location on the website, a request to enter your mobile phone number or email address, a prohibition not to leave the website;
- a promise to offer multiple packages at once as a discount;
- A mandatory feature of a counterfeit drug will be a literally screaming statement about its complete naturalness, secret multicomponent composition and the absence of any contraindications.From the point of view of the authors of the site, such a medicine can be used by all patients, healthy people, as well as children, pregnant and lactating women.
- A very characteristic sign of online fraud is a suspiciously high price.
- An obligatory feature of such a fake site is the presence in the most visible place of a large number of extremely positive reviews, interspersed with exclamation marks and gratitude from patients who “cured” themselves, their parents, children and even cats and dogs from helminthic infestation.However, when you try to add your review, it is not possible because all reviews are nothing more than a simple screenshot of a dead image with no interactive form;
- In addition, on such a site it is simply impossible to ask a question and find out the owner of this domain.It turns out that the site is secret and disguised, and there is simply no official information on the site about the legal entity or company that produces or sells this drug.Therefore, it is simply physically impossible to legally contact this product, provide information or make a complaint regarding the quality of this product;
- Finally, if the website presents a registration certificate that actually exists and is not a fake, then in most cases it is not a drug or even a dietary supplement.The vast majority of these medicines have approvals and certificates from the cosmetic sector and do not even go through a registration process.
Now that we have covered the most important thing and warned our readers about the possibility of deception on the Internet, it's time to talk about who worms and parasites are.We have already said above that there are many more parasites than worms.Finally, the protozoan Plasmodium, the causative agent of malaria, which is an intracellular parasite and causes fever attacks and malarial jaundice, can also be considered a parasite.A dysentery amoeba can be viewed as a parasite that can kill a healthy person within a few days, debilitating them with bloody diarrhea.
Who are worms?
But worms are parasitic worms, and humans are either an intermediate host or a definitive host for them.The definitive host is the living creature in whose body the parasite reproduces and lays eggs.And intermediate hosts are all organisms that the parasite leaves sooner or later to find the final host.For example, the pathogen of opisthorchiasis or cat leech is “hospitable” in the human body, i.e. in the body of the final host.
A person with opisthorchiasis releases eggs into the external environment through their feces.But under no circumstances can another person become infected from a sick person.After all, the life cycle of Opisthorchis is such that these eggs enter freshwater water, overwinter in freshwater organisms, enter the muscle tissue of fish of the carp family, transform into special life forms - metacercariae - and only then end up on a person's table in poorly fried or poorly cooked fish meat.This is the only way to get infected, and even if you put dirty hands filled with opisthorch eggs in your mouth, nothing bad will happen.The eggs only become active in freshwater environments.
So all worms are worms.They can be as small as pinworms, no more than 1 cm long, and as large as roundworms, which can reach almost a meter in length.Most of the rivers of Western Siberia are a natural reservoir of the above-mentioned opisthorchiasis, in which almost 100% of fish from the cyprinid family are infected.
Perhaps the record holders are tapeworms that reach gigantic sizes.The already mentioned wide tapeworm, which causes diphyllobothriasis in humans, can reach a length of more than 10 meters!At the same time, its entire body, with the exception of the head, consists of repeating, similarly arranged segments, which mature, tear off from the end of the parasite and release a large number of eggs along with the feces.Each of these segments has no digestive or nervous system and is a hermaphrodite, i.e.Mature segments have specific muscles so that they can crawl out of the anus even at night and be active for some time.
We can assume that such helminths have achieved complete perfection and the highest specialization, since their existence has only one goal: the production of eggs and existence in conditions that can be considered the most suitable.In the intestinal lumen they are warm and safe, they absorb food through the entire surface of the body and do not even have a digestive system.However, if we think philosophically, humanity differs little from the same helminths in terms of the meaning of their existence.The purpose of our existence as a biological species is to reproduce our own species, just like all other living things.Let's talk about which worms are contagious and which are not.Above we have already started to talk a little about it using the example of opisthorchiasis.
About contagious and “non-contagious” worms
There is a difference between these concepts: in the body of the definitive host, adult individuals reproduce and lay eggs.However, this does not mean that a person who produces a large number of eggs is always contagious.Therefore, the eggs of the liver fluke, which come out with the feces, must necessarily visit a fresh pond, the larval stages must undergo transformations by passing through the bodies of freshwater mollusks, and only next year the “young parasites” become dangerous to humans.
Roundworms living in humans constantly lay eggs.However, they need at least several weeks of “basking in the sun” in the upper layers of warm soil to acquire the ability to infect.Poorly washed greens are most often eaten.
Perhaps the strangest and safest way was invented by pinworms.They rejected the participation of other organisms in their development, the release of eggs into the external environment and all “tricks”.At night, the female crawls out of the anus and lays eggs near the anus.After a few hours, the eggs are activated by the “fresh air” and cause itching.When scratching, the eggs get under the nails and then into the mouth.In this way, a smooth closed cycle of self-infection is created, which ensures the persistence of enterobiasis (as pinworm parasitism is called) in a person and in groups of children.
Lonely hikers are murderers
But unfortunately, helminths sometimes also have problems with reproduction.They do not multiply in our body, but accumulate in another, but they do not succeed and they enter our body randomly and at the wrong time.For example, there is a disease such as trichinosis.You can become infected by eating raw meat, such as frozen bear slices.Once in the human muscles, the larvae curl up there, encapsulate themselves and mistake the human body for the body of a wild animal.In the wild, there is a high probability that a given animal will be eaten by another, such as a wolf.As a result, the larvae from the muscles enter its body under the influence of the wolf's stomach juice and, according to the plan, live and thrive in it, turning into adult parasites and releasing eggs.
But if a person eats such meat, then there is no way out of the human muscles.Of course, there is such a small probability that this person suffering from trichinosis will be eaten by someone, for example, the same wolf, and then the normal life path of trichinosis will be restored.However, since this is unlikely to ever happen, such accidental entry of trichinae from bear meat into our body leads to a “biological dead end”.And Trichinella doesn't go anywhere else.
It is possible for a person to be not only the definitive host but also the intermediate host at the same time.We are talking about the pork tapeworm, which causes the disease taeniasis: if eggs from the human intestine are thrown into the stomach or even higher along with vomit, for example, they can cause a lot of trouble.
As soon as the eggs are in the gastric juice, they begin to “hatch” and from them arise the life forms that should normally develop in the body of a pig, which can consume these eggs along with its food contaminated with human feces.If this happens in the human stomach, when these eggs have left the small intestine, then the larvae emerging from the eggs penetrate the stomach wall, enter the bloodstream, spread to many organs and systems and grow there in the form of bubbles that simulate cancerous tumors.This human disease with an intermediate form of pork tapeworm is called cysticercosis.
Cysticerci can mature in the liver, brain, mimic malignant tumors, and cause neurological symptoms or even in the eye.Inside the capsule, the larval stage of the pork tapeworm is surrounded by a thick membrane and is well protected from various drugs by being sealed off from the bloodstream.Such stages must be treated surgically;This is a fairly complex and lengthy treatment.Unfortunately, even now it doesn't always end successfully.
Champions of Horror
Perhaps the most dangerous of these creatures are small worms – Echinococcus and Alveococcus, or more precisely their larval stages.The “idea” of the parasite (and the definitive host is dogs) is that grass contaminated with wolf feces is eaten by livestock, the parasite goes through a development cycle in it, and then the dead or hunted animal is eaten by a wolf or arctic fox.
But here too, humans are standing in nature's way: rare, but cases of infection occur when handling sick dogs (eggs in their fur) or when removing the fur from sick arctic foxes.In the human body, echinococci form bubbles in the organs that grow and can reach the size of a child's head.At the same time, a liquid containing toxic succinic acid is created inside the bladder, so that severe poisoning is possible if the bladder ruptures (for example due to an injury).
But the worst thing is that secondary, tertiary bubbles (daughter, grandchildren, etc.) are constantly forming inside the bubble, like “matryoshka dolls”.Each of the bubbles has a head and hooks with suction cups that are ready to use.In the event of an injury, all of this ends up in the abdominal cavity, for example.
It turns out it can be even worse.Alveococcus, a parasite of rodents and dogs, whose eggs can be carried into the mouth with unwashed root vegetables and herbs, is capable of the most aggressive lines of attack: while other parasites are “subject to fate” and live quietly in the muscles and internal organs of animals, waiting to be eaten, Alveococcus acts.
The demise of the intermediate host is getting closer.From an evolutionary perspective, this is a smart move: it just shortens the lifespan of the embryo.And the Alveococcus does this very gracefully: its bubbles multiply not inside, under a common membrane, but outside.They grow like a sponge, growing and destroying organs and tissues, which is why the disease is called “parasitic cancer”.
Alveococcosis is the only disease caused by “worms” with an extremely serious prognosis and, in advanced cases, high mortality.
But fortunately, most helminthic infestations do not follow the script of the film “Alien”, but have clear signs and symptoms that prompt a visit to the doctor.What symptoms are we talking about?
Clinical signs of infestation
Of course, a lot depends on the localization or location of the parasites.Since in most cases parasites are located in the intestines, it is clear that the symptoms of helminth infestation can include various intestinal problems.However, it must be taken into account that the body becomes infected and allergenic at the first contact with the parasite, and a completely different clinical picture can occur with prolonged coexistence.Parasites can release toxins, absorb our proteins, fats and carbohydrates and cause the patient to become exhausted;they reduce immunity.As shown, long-term infection with opisthorchiasis significantly increases the risk of developing liver cancer or hepatocellular carcinoma.What signs indicate an acute infection with worms?
Acute symptoms of helminth infection
When a parasite invades the human body, the immune system initially responds to the introduction of unknown substances that are products of the parasite's vital activity.The most common are:
- Fever;
- Itching of the skin, including in the anus, urticaria;
- muscle pain;
- Cough, difficulty breathing, bronchospasm, shortness of breath may occur;
- abdominal pain, stool instability, diarrhea;
- asthenovegetative symptoms are expressed (weakness, lethargy, reduced performance, sleepiness during the day and insomnia at night);
- Anemia;
- the appearance of a skin rash.
The specificity of parasites and their migration routes in the body should be taken into account.So, when infected with pinworms, the invasion is constantly accompanied by itching on the skin, and the itching occurs in the anus.Myalgia (muscle pain), facial swelling and severe pain in all skeletal muscles are characteristic of trichinosis, in which parasite larvae are encapsulated in the muscles.
Pulmonary symptoms are characteristic of migratory larvae that travel through the bloodstream via the pulmonary circulation and settle in the lungs.In some cases, direct microscopy of sputum can reveal parasite particles.This is a direct indication of invasion and treatment should begin.
Abdominal (intestinal) symptoms are most common because most parasites are still located in the intestines.In small children and malnourished people, and especially with a large number of parasites, malabsorption syndrome occurs, in addition to abdominal pain and unstable stools.Due to the influence of the parasite's toxins, the appetite decreases and the parasite "appropriates" everything that the owner receives.
Anemia is a characteristic sign of the localization of parasites in the intestines, which can damage the intestinal wall.In addition to suckers, many tapeworms have hooks to stay in one place, and parasites such as hookworms (roundworms), which suck themselves into the human intestine, feed on his blood.The result is dizziness, reduced blood pressure, drowsiness, reduced temperature, pallor, a sharp decrease in exercise tolerance and shortness of breath.
Naturally, all symptoms are more pronounced in young children than in adults.
How do you behave to avoid getting infected?
Finally, I would like to give some simple tips that will help you avoid infections and becoming an army of helminths:
- Always wash vegetables and fruits thoroughly, especially greens in areas where soil can accumulate.
- When traveling and hiking, only drink bottled water.
- After washing, it is advisable to scald the greens with boiling water and use drinking water for washing.
- It is necessary to control flies, especially to prevent them from crawling on food, by covering them with muslin.
- Wash your hands thoroughly before eating and teach your children not to bite their nails or put their hands in their mouths.
- You should not drink raw water and try not to swallow it when swimming in fresh water.
- Don't go barefoot in the tropics;
- Don't swim in tropical freshwater lakes, even if locals swim in them.
- Do not eat stroganina made from raw meat (especially game and bear meat), as this can lead to infection with trichinosis.
- Fish must be thoroughly baked, boiled or fried for at least an hour, especially the carp family: bream, carp, crucian carp, common carp, ide, etc.;
- Do not eat meat from pigs and cows that have not passed veterinary inspection.
In conclusion, the use of anthelmintics or anthelmintics for prevention as well as in the form of self-medication is not a good idea.For example, if a person has pinworms and severe itching in the anus, drug treatment alone is not enough.At night, when a person sleeps, he mechanically combs the anus area and drives the eggs laid that night under his fingernails.
When he takes the medication, he still has eggs under his nails that sooner or later end up in his mouth.Thus, the mechanism of self-infection will persist despite treatment and such treatment will be useless.To prevent pinworms from laying eggs on the skin of the anus, the treatment of children involves inserting a tampon lubricated with petroleum jelly into the anus at night.Pinworms cannot overcome this natural barrier and lay eggs;They are exposed to the drug and die.
And if at the same time the child has short-cut nails, if he is used to washing his hands and brushing off the dirt under the nails, if the bed linen is regularly changed and ironed with steam, and if not only the child, but also all adults living with him are treated, then the chance of successful healing increases many times over.Therefore, before making irresponsible, independent attempts at “deworming”, you must definitely visit an infectious disease specialist, undergo an examination, make an accurate diagnosis and follow the instructions of specialists.
