Contact helminthiases are infestations in which infection occurs from person to person. Thus, most often pinworms are transmitted( then an infestation called "enterobiosis" is diagnosed) and dwarf chains( hymenolepidosis).These are the most common infestations, they are capable of proceeding in complex form, which is why it is so important to know how the pathogen gets inside the human body, what measures help prevent infection.
Enterobiosis ranks first among all helminthiases that occur in children. It can provoke pinworms - small round worms, the length of which is only one centimeter. They parasitize in the large intestine. Both males and females participate in the fertilization, the males die after the sexual act, the females are able to lay up to one and a half thousand eggs. They do this only at night, crawling out of the anus for this. The eggs are attached directly to the skin and ripen for six hours. This process is accompanied by itching, wanting to get rid of it, a person combs the anus, invasive eggs are hammered under the fingernails, and then settle on all surfaces to which the sick person is touching. From eggs, larvae are born, they become sexually mature after two weeks, a female lives for a month. It is not difficult to calculate how many eggs she will have time to give birth in this period. That's why contagious helminthiasis is considered dangerous.
Even enterobiasis is dangerous because a large accumulation of worms inside the intestine leads to the development of complex diseases. One such is an intestinal obstruction. During the course of a severe invasion, the patient can complain not only of the itching in the perineum, but also of nervous disorders, abdominal pains, constipation, or frequent diarrhea. If one member of the family is diagnosed with contact helminthiasis, all members of his family are examined, other people who are nearby or who serve the patient during the day.
Contagious helminthiosis - hymenolepidosis
It occurs when a dwarf tangerine enters the body. This name he got because the length of an adult specimen of a tapeworm is only 5 cm. He has a body and a head. There are suckers on it, there is a trunk and hooks. With the help of them, the parasite is attached to the intestinal mucosa. The contact helminth lives for two months in the human small intestine. It is there that he parasitizes and lays eggs. Inside everyone is an invasive larva. Such contagious helminthiasis is most often found in countries with a hot climate.
How dangerous is this contact helminth? Hooks, crashing into the mucosa of the small intestine, provokes the formation of necrosis, necrotic wounds, like ulcers, disappear, and internal bleeding opens. Anemia, asthmatic bronchitis, headaches, rhinitis are frequent satellites of contact helminthiasis. In addition, the products of the dwarf chain are toxic, they cause allergies. If you do not start treatment on time, complications will arise, which will be extremely difficult to treat.
