Types of worms in humans

Worms should be interpreted as parasitic worms that invade the human body. There are similar representatives in some animal species.

Worms appear in the human body after infection with parasitic eggs.

After conducting several studies, scientists have concluded that more than 25 percent of people around the world know from their own experience what helminthiasis is.

As a general rule, nematodes and fungal worms are the most common. These types of worms can find a place in any organ in humans.

The most popular place for helminths is the intestines. And only then do they live in the organs of the liver and lungs.

But this is no exception when parasites find their place in the eyeball or muscles.

The external characteristics of worms in humans

When diagnosing a patient’s body, the doctor must have all the knowledge about the possible invasion of the worms and how to remove them in the future.

Thanks to this information, complex conditions that can occur in the form of complications after infection with helminth eggs can be avoided.

For this reason, it is important to identify worms in the human body at the time of infection, e. g. in the early stages.

One of the most popular types of worms is tapeworms and fungal worms. They look like a white worm.

Surprisingly, their thin and elongated body can reach 40 cm, with an average length of 20 cm.

But that doesn’t mean there aren’t more solid-sized parasites. These include wide band.

It was so named because it resembles a ribbon on the outside. Its length varies within meters.

Classification division of worms

What types of worms are found in the human body? If this issue really concerns you, read the information below in the article.

The types of helminths are divided according to their position in the body. There may be tissue and luminal worms.

tissue worms

Tissue worms are understood to be types of worms that preferentially settle in the parenchyma of the pancreas, liver, brain, muscles, and lung tissue.

This is the reason why the pathology has several names: paragonimiasis in lung damage, echinococcosis with liver disorders, filariasis - lymph nodes, cysticercosis with brain damage.

translucent worms

This type of helminth differs in that it prefers to live in the lumen of the gut. These worms include tapeworms, tapeworms, whipworms, dumplings, hookworms, broad tapeworms, and other worms.

Worms are also divided into species according to their body structure. They can be round, flat, ribbon and other varieties. But this will be discussed in more detail later in the article.

Circle view of human worms

This is a fairly common worm called nematode.

Their bodies are shown in a round shape, with worms reaching 40 cm at most, but there are also 5 mm.

They choose nematodes instead of intestines, but they may colonize tissues or other organs.

The prevalence of these types of worms is explained by the fact that eggs are transmitted during the use of unwashed vegetables or fruits. This type of pathology is considered a disease of dirty hands, so children most often suffer from round parasites who try to get their dirty hands in their mouths.

Other types of nematodes are also subdivided. Are:


It provokes the development of ascariasis. These are quite large worms that can reach 40 cm in length.

They differ from their counterparts in the shape of the spindle. Similar representatives are supported in the small intestine area.

During life, they move to the heart, liver, and lungs. They carry great dangers when transported through the human body.

The situation is that all organs and channels suffer from worms. Their life cycle is about a year, but during this time a person has to face many unpleasant consequences of the manifestation of allergies, disruption of the digestive system, as well as internal bleeding, blockage of the intestinal system.

If spindleworms appear in children, this fact can negatively affect development. The child may be far behind his or her peers in development.

These parasites enter the child’s body in the same way with unwashed hands with soap and dirty food.


Their bodies are gray. The length of such worms is 5-10 mm. The main localization of parasites is the intestine.

Most commonly, fungal worms affect people who have swallowed their eggs through the fruit of unwashed vegetables and / or fruits.

To be a mature individual, eggs must go beyond the 14-day period. The total lifespan of parasites is about a few months.

They disrupt the normal functioning of the digestive system, which exhausts a person.


These worms differ in their habitat. They settle mainly in the colon.

The body of the worms sucks 3-5 cm, placing blood on the wall of the organ. These worms provoke trichuriasis disease, severely sending the body.

They can exist in the human body for about 5 years. During this time, the person will have a severe stool injury, a problem with the urge to eat, e. g. appetite may increase or decrease, abdominal pain and even anemia may occur.

You should not ignore the fact that you are infected with whipworms because the acute phase of appendicitis may begin in the background of their vital activity.

This happens when worms enter the appendix. A relentless blow to health is being measured, so efforts should be made to remove whipworms quickly.


Another type of worms that are not large in size. They can reach 2-5 mm, but that doesn’t mean worms don’t attack health.

They cause trichinosis, which is manifested by high fever, swelling, fever, and allergic reactions.

You can also catch trichinella with uncooked pork or game. These worms penetrate the muscles of the airways or face and hit the tissues.

For 3 weeks, the eggs of the worms can be encapsulated so the person recovers. But there are more difficult situations that lead to death.

Another type of roundworm is Toxocara. They are found in the dog's body. They appear to be spindleworms, but the length of the body is 15-30 cm.

This type of worm can be in the human body. When this occurs, the development of toxocariasis is observed, accompanied by damage to internal organs, allergic reactions, and other body disorders.

It should be noted that larvae are not able to develop into mature individuals when they enter the human body, this is only possible in the body of dogs.

The symptoms of roundworm infection vary depending on the human health condition and the number of worms in the organs.

Ribbon type worms in humans

Tape worms pose a major threat to human health. They are called cestodes. These are worms that grow to 18 m. It is common to divide them into two types:

  • ribbons;
  • chains.

In order to develop into mature individuals, worms must change hosts. One stage in this process is to exist in the body of the cattle.

The brightest members of this species are shown in the detailed description below.

wide ribbon

It reaches about 10-15 meters. He chooses the small intestine as his habitat.

It can trigger the development of diphyllobothriasis. The tapeworm species enters the body when someone has eaten an incompletely cooked freshwater fish that has been attacked by parasitic larvae.

The infection is accompanied by severe abdominal pain, indigestion, and anemia. This kind of worm, like many other cestodas, looks really fantastic.

Bull tapeworm

In length, this species of tapeworm can reach 18 meters. This species is one of the largest in the human body.

This provokes the development of its pathology to teniarin, which leads to physical exhaustion of the body. In addition, a person may experience intestinal obstruction, a disorder of the central nervous system.

This type of worm enters the body through the affected beef with parasitic larvae. The worm settles in the small intestine, which affects all organs in the human body.

Swine tapeworm

This type of parasite enters the human body through infected pork. The worms can be 8 m long.

They usually settle in the intestinal tract where they perform their parasitic activity.

Teniasis causes severe stomach upset with allergic reactions and nervous system disorders.

Another dangerous type of tapeworm is echinococcus. It settled in the bodies of dogs and cats.

Humans are chosen as intermediate habitats. Even in such a short time, it can completely damage the human body, provoking the development of echinococcosis.

The eggs of the parasite reach the larval stage. They then grow into the tissue membrane of the organs, causing cystic formation.

The manifestation of parasitic echinococcus can only be surgically removed. These individuals have lived in the bodies of adults for decades and experience the process of their development in the flesh.

Trematodes. They differ from other types of tape parasites in that they have special suction cups on the body that allow them to be absorbed into the walls of human organs and tissues.

They drain blood and useful items. Such worms can be up to 1. 5 m in size, resembling the leaves of a plant at first glance.

The main source of flakes in the human body is again undercooked, poorly cooked fish or seafood.

During their developmental stages, these parasites change hosts. The main varieties of vultures are the following subspecies:

  • liver fluke;
  • luck.

Based on the above information, it is worth concluding that almost all worms enter the human body through meat.

In fact, this is not always the case; there are also parasites that affect the skin. They will be discussed below.

Types of worms that affect people's skin

Helm samples called rishtha can infect a person’s skin and soft tissues. They provoke Dracunculiasis.

They can be up to 120 cm long. Rishta affects the tissue under the skin or muscle.

The infection occurs during the consumption of untreated water. Infection can occur during bathing because the parasites get through the fluid into the gut and then into the fiber.

When helminth reaches sexual maturity, you have the opportunity to select substances that have a negative effect on the human body. As a result, the skin begins to corrode. There will be an ulcer at the site of the lesion, which the parasite will use to remove its larvae.

This phenomenon is accompanied by severe itching. Very often such phenomena are recorded in the tropics. As an intermediate host, marine worms choose freshwater crustaceans, i. e. Cyclops.

In contact with water, the person can get into the skin and intestinal acne. The mode of infection with them is percutaneous.

Parasites cause skin blemishes and penetrate the bloodstream. Risk factors include walking barefoot on the ground, working with the ground, swimming in dirty lakes.

Diagnostic measures and treatment of helminthiasis

If a worm is suspected in a person, your doctor will recommend a blood and stool test.

In a general blood test, changes in leukocyte counts are shifted to the right. The number of eosinophils will be pronounced.

The contents of urine, sputum and stomach, duodenum also play an important role. This is why your doctor may prescribe scraping in the anal area and rectum.

Once the type of worms in the human body has been determined, the person skilled in the art must select the appropriate drug treatment, and effective conventional prescriptions can be used.

Of course, it is worth understanding that preventive measures must be followed to avoid re-infection.

For successful treatment of an infected person, it is important that the deworming is performed by the whole family, and simple hygiene rules must be followed. The treatment is usually repeated 2 weeks after the first stage of worm relief.

Folk remedies are well established and many believe they are better than the anthelmintic drugs offered by pharmacological organizations.

Their main advantage is the absence of contraindications and side effects.

It is important to note that it is impossible to start prescriptions for popular traditional medicine without consulting a doctor.

It is important to take into account the special type of worms, their localization, and the specifics of their organization. If you make a mistake during your chosen treatment, the infection situation can become even more catastrophic.

Expert advice

  1. Treatment with folk remedies should begin with dietary therapy. Meat, fish is better not to eat for a week, i. e. stick to a vegetarian diet. This will weaken the forces of the parasites and therefore make it a little easier to deal with the worms. It is only important to keep in mind that fasting will not be a successful idea in this case. Lack of food in the body does not affect the strength of the helminths, but the person feels much worse.
  2. Wash hands with soap before eating.
  3. Food processing is required.
  4. The timeliness of infection detection and the course of therapeutic treatment are very important. In this case, the recovery time is minimized.
