The difference between roundworms and pinworms is quite significant; this article will help you obtain detailed information about the unpleasant consequences that these parasites can bring.

Infection with parasites can lead to chronic diseases if helminth infections are not treated promptly. Helminthiasis is a disease that is caused by various types of parasites. The most common parasites are worms that parasitize the intestines of adults or children. Worms belong to the class of roundworms. These include roundworms and pinworms. The presence of these parasites in the body entails injury to the intestinal mucosa, which can lead to a lack of nutrients in the tissues.

Parasites can be identified by having stool or blood tested. These species can be causative agents of ascariasis and enterobiasis. The names of these diseases depend on what pathogens they are caused by. If, in the case of enterobiasis, white worms can reach no more than 1 cm, then with ascariasis, worms can reach up to 30 cm.

Difference between pinworms and roundworms

Round white-gray worms, measuring 5 mm in length in males and up to 12 mm in females, are called pinworms. With the help of a vesicle - a small tubercle - they attach to the intestinal mucosa.

The larvae that enter the human body grow after two weeks and begin to eat what enters the intestines or feed on the contents of the blood. They most often choose to live in the small intestine and the upper part of the large intestine. Pay attention to the photo, pinworms and roundworms live only a month, but a sexually mature female, after fertilization, approaches the anal area and lays eggs in the folds of the anus. Most often this happens at night. Due to the fact that the person is asleep and motionless, and the intestinal muscles are relaxed.

  • The female dies after laying eggs. She is capable of laying up to 13 thousand eggs at a time.
  • In just six hours, new larvae hatch, find themselves in a favorable environment, and begin their development and parasitism.

Roundworms and pinworms are the same thing, they have a round shape and a white body, they parasitize in the human intestines. But, if female pinworms can reach only 12 mm, then female roundworms can grow up to 40 cm in length. Males are almost two times smaller and can be up to 25 cm. When roundworm eggs enter the human body, their hatching begins. Roundworms and pinworms are one and the same, and they are dangerous because after the larvae appear in the body, they penetrate the intestinal walls and enter the blood vessels.

With the help of blood, parasites can enter various human organs. What else is dangerous about helminths being in the blood is that they eat not only useful substances in the body, but also red cells. Unlike pinworms, roundworms live longer. Their life period lasts a whole year.

Roundworms are more dangerous because they can infect the entire human body in just one day. Such rapid infection also occurs because the female is capable of laying 200 thousand eggs in one hour.

Characteristics of pinworms

The worms that cause enterobiasis are called pinworms. They are off-white in color, vesicles that serve to attach to the intestinal mucosa. Females reach a length of 12 mm, males - 5 mm. Pinworms parasitize in the small, blind, ileum. They feed on blood and intestinal contents.

Pinworm eggs enter the human body with dirty hands, water, food and are localized in the intestines. Pinworms soon become larvae that attach to the intestinal mucosa. 15–30 days pass, the larvae become adult, sexually mature pinworms capable of fertilization and laying eggs. After fertilization, the female moves through the intestines to the anus, laying eggs around the anus.

Pinworms usually do this during sleep, when the muscles are relaxed and are not disturbed by intestinal contractions. During one oviposition, the female is capable of laying 13,000 eggs; having completed her mission, she dies.

5–6 hours is enough time for the larvae to hatch from the eggs. Pinworms cause itching when they move, so the patient scratches the area around the anus. And thus, again with dirty hands, the larvae enter the oral cavity and intestines.

Enterobiasis is different in that the parasites that cause it can actively move inside the intestine and go beyond it, for example, to lay eggs. Helminths can be transmitted through skin-to-skin contact with a sick person through a handshake. Therefore, the disease is equally common in adults and children.

Pinworms, Giardia, tapeworm, helminths, tapeworm... The list goes on for a long time, but how long are you going to tolerate parasites in your body?

Most often, these parasites have the same method of infecting the human body. If you do not wash your hands after using the toilet, after going outside, or before eating food, then you are likely to introduce parasites into your body. But there are some differences in infection with worms, since roundworms are quite tenacious and can be found on different objects and in different places. For example, in raw, untreated water or on objects in an unsanitary environment. They remain on fruits and vegetables if they are not washed properly. It is also worth remembering that worm larvae can be introduced through food if it is poorly processed or has not undergone heat treatment at all.

It is not always possible to become infected with helminths from another person, since the larvae can remain on underwear or bedding. Therefore, we must not forget that simply taking a course against worms is not enough. It is definitely recommended to change your underwear and bed linen. In addition, eggs can be carried by insects that come into contact with food, such as flies or cockroaches. Moreover, eggs can be inhaled into the lungs after inhaling dust.

Prevention of helminthiasis

Prevention of the disease follows from the routes of infection. And in this, roundworms will not differ from pinworms. They appear in the human body mainly due to non-compliance with hygiene rules. You can also become infected with pinworms from physical contact with a person suffering from helminthiasis - what is the difference from roundworms. Worm eggs can be carried by insects. They can also enter the body through food or inhaled dust.

Prevention consists of observing the rules of personal hygiene, which should become life companions. Treatment is much more difficult than preventing the disease. Recently, control over the sanitary situation in enterprises and the quality of products has weakened; you will have to take care of yourself.

The following recommendations must be followed:

  • Wash your hands regularly before eating, after eating, going to the toilet, or going outside. The more often you wash your hands, the lower the risk of helminths;
  • Drink only boiled or filtered water. Water from a tap or natural reservoir may contain worm eggs;
  • vegetables and fruits must be washed thoroughly - it is better to pour boiling water over them and wash them with a specially designated sponge or washcloth;
  • minimize the time spent in unsanitary conditions - this means complete order in the house and avoidance of dirty places;
  • subject food to deep heat treatment - prolonged exposure to high temperatures kills parasite eggs;
  • do not have contact with stray dogs or cats, have your own animals examined by a veterinarian;
  • maintain personal hygiene - this means not only washing your hands, but also regularly washing and ironing clothes, caring for your nails, etc.

Ascariasis and enterobiasis have similar routes of infection, so preventive methods are the same. However, perfect adherence to the rules does not guarantee safety from these diseases. Infection from insects or air cannot be ruled out; it is impossible to protect yourself from this.

Differences in Symptoms of Infection

As mentioned earlier, the presence of parasites in the body is not always obvious. Therefore, you need to be very attentive to your body. You should not ignore the fact that pinworms and roundworms are different, which means the symptoms may differ; this answers the question of how to distinguish pinworms from roundworms.

General symptoms are weakening and lethargy of the body, as parasites eat large quantities of beneficial substances in the body. In addition, infection is accompanied by severe intoxication due to the release of toxic substances by parasites. After this, a severe allergic reaction may develop. Other symptoms of infection include weight loss, loss of appetite and digestive problems. In addition, the mucous membranes and skin turn pale. As a result, shortness of breath, malaise and insomnia appear. Skin rashes occur due to problems with the immune system.

When infected with pinworms, the symptoms are not so obvious. There is a feeling of severe itching in the anal area. The itching may not stop for several days, then it disappears completely. This happens because the female moves towards the anal canal to lay new eggs in the anal folds. Further symptoms may include pain in the abdomen, severe itching and abnormal bowel movements. When the disease takes on an advanced form, the infected person may experience headaches, irritability and insomnia. Parasites, in this form, can reach a woman’s vagina and uterus, which will cause problems in the gynecological area.

If you consult a doctor at the first symptoms, complications can be avoided. After the analysis, the doctor will prescribe the necessary medications for treatment.

Symptoms and treatment of helminthiasis

Enterobiasis and ascariasis are caused by different parasites; their symptoms, course of the disease and treatment differ. Roundworms cause bright, rapid symptoms by rapid reproduction and poisoning of the body with toxins. The patient has:

  • pale skin;
  • loss of appetite, weight loss;
  • constipation or diarrhea;
  • general weakness;
  • irritability, insomnia;
  • pain in the lower abdomen;

The disease with roundworms is characterized by a rapid onset of symptoms, because, unlike pinworms, they multiply more slowly and only affect the intestines, and in advanced cases, the genitals. Therefore, the symptoms of enterobiasis appear slowly. Among them are itching in the anal area, repeating every 2-3 weeks, mucous inclusions in the stool, and stool disorders.

Treatment can only be carried out by the doctor who made the diagnosis. At home, it is impossible to accurately determine the disease. Anthelmintic drugs are the strongest antibiotics that kill living organisms of a fairly large size, so they are toxic and should not be taken without medical supervision. Treatment at home is acceptable, but after agreeing with a specialist on the course, dosage and type of treatment.

Ascariasis, which differs from enterobiasis in being more dangerous. These helminths are larger than pinworms, reproduce faster, and have a long life span. The ways in which diseases spread are the same, and they are prevented in the same ways. Symptoms, medications used in treatment and the course of the disease are different.

Treatment against parasites

Since roundworms and pinworms belong to the same class of worms, when asked how they are treated,

one answer has been given, against these parasites it can be not just similar, but identical. Worms begin to secrete toxic substances that poison the human body from the inside. In addition, their vital activity disrupts the functioning of the intestinal microflora, which leads to dysbiosis. Since the immune system is weakened during infection, a person may experience allergic reactions.

Roundworms are more dangerous because they damage internal organs and can cause leukemia due to the absorption of red cells. Definitely, it can be noted that helminths are very dangerous for small children and pregnant women. Sometimes, the presence of roundworms in the body slows down the development of the fetus, as the parasites absorb all the nutrients. Children with infection have decreased immunity and frequent allergies.

For proper treatment, you must first consult a doctor, do all the necessary tests, after which the doctor will prescribe the necessary remedy. Today, the pharmacy has a sufficient amount of products that will help rid an infected person of worms in the shortest possible time.

Products such as Levamisone and Pyrantel are also suitable. After the course is completed, you need to take all stool and blood tests again. In the event that the drug does not work and not all parasites are killed, it is necessary to repeat the course of drugs.

Pinworm infection is well treated with Vermox and Pyrantel. You can also use Vormil. The treatment algorithm is similar to treatment against roundworms. First, tests are taken, a course of treatment with these drugs is carried out, if the treatment does not help based on a repeated analysis, then the course needs to be repeated again.
