The risk of contracting these parasites is quite high, and the consequences can be dangerous. Therefore, it is necessary to know the signs of ascariasis in adults and children, how to identify and how to treat ascaris.

Characteristics of the causative agent of the disease

The human roundworm belongs to the class of roundworms, nematodes. The parasite lives in humans in the small intestine, has no organs for sucking or otherwise fixing it in place. These parasites have a clear bisexual separation, hermaphroditism is not peculiar to them. The size of an adult female can reach 40 cm, and a male - 25 cm.

A female worm alone can lay about 240 thousand eggs every day. These future roundworms do not stay in the intestines, but are excreted from the body naturally.

Once in the soil, they go through a developmental stage, and then they can persist for a long time until they find themselves in favorable conditions, that is, in the human body.

Ascaris eggs are highly resistant to adverse environmental factors, as they are covered with several layers of protective shells. The most suitable temperature for them is 23-25 ​​degrees, but they even tolerate freezing, while maintaining their viability.

How roundworms enter the human body

Once in the soil, the eggs of the worm develop and turn into larvae, but cannot grow and reproduce until they are in the human body. Most often, they enter the host's body through poorly washed fruits, berries of plants, which can get contaminated soil, dirty hands, as well as through unboiled water contaminated with parasite eggs.

For this reason, ascariasis is most common in rural areas and among young children, who do not always carefully observe hygiene standards.

Once in the human intestine, mature eggs shed their protective membranes, enter the bloodstream and go through a stage of migration, moving through the body. Once again in the intestines, roundworms enter the so-called intestinal stage, begin to grow and multiply, laying new eggs.

The life cycle of one individual is only a year, and if during this period a person can not become infected again, then the disease will stop on its own. It takes about three months from penetration into the human body to the development of a sexually mature individual.

Symptoms of ascariasis

Signs of infection with roundworms depend on the massiveness of the invasion, localization and stage of development of helminths.

Ascaris in adults causes symptoms of less intensity than in children. At the same time, a child under one year old who is breastfed cannot become infected with parasites, since it is protected by special antibodies obtained with mother's milk.

Signs of an early stage of ascariasis

At the stage of migration, helminths almost do not give pronounced symptoms. The person may feel mildly unwell. In some cases, subfebrile condition is observed, a cough with a small amount of sputum discharge.

Ascariasis in a child with significant invasion can cause rather pronounced manifestations. The temperature rises to 38 degrees and above, there are symptoms of intoxication of the body, febrile symptoms, severe headaches. On examination, signs of hepatomegaly and splenomegaly are revealed.

When diagnosing at this stage, it is possible to detect the presence of infiltrates of various configurations in the lungs. In laboratory studies, a slight increase in leukocyte mass can be detected, the erythrocyte sedimentation rate, as a rule, does not increase.

Manifestations of the intestinal stage of invasion

In the later stages of the disease, the symptoms of infection with ascaris worms in humans are more pronounced and varied. Signs from the gastrointestinal tract, nervous system, asthenic syndrome and neurological disorders appear.

Being in the intestine, helminths provoke a complex of dyspeptic symptoms: alternating diarrhea and prolonged constipation, increased gas production, and sometimes nausea. The progression of the disease leads to a pronounced decrease in appetite, vomiting, pain in the abdominal region, itching sensations in the anus may appear.

Neurological disorders include sleep disorders: insomnia, restless shallow sleep. Convulsive muscle contractions are sometimes noted. Fatigue, frequent dizziness, and cephalalgia are also characteristic of this stage of ascariasis.

In children, ascariasis manifests itself more intensely. Frequent colds may begin against the background of a significant decrease in immunity. Various infections, purulent diseases, skin reactions, stomatitis are possible.

During the migratory stage, parasites enter the bloodstream through the intestinal walls and can injure them. With massive invasions, perforation of any part of the intestine may occur.

A large number of worms become cramped, they penetrate the liver, gallbladder, which leads to the development of cholecystitis with a purulent course, enlargement of the liver and spleen, the formation of abscesses in the affected area, purulent peritonitis.

During the migratory stage, ascaris larvae can mechanically damage various organs. This is especially dangerous for children in whom some systems are in the process of formation and are very vulnerable. As a result of the movement of worms in the body, varying intensity of hemorrhage, perforation in the cavity organs, the appearance of ulceration and foci of necrosis can occur.

If there is no treatment, adult roundworm can absorb a significant part of nutrients, useful vitamins and minerals, which leads to the development of anemia, vitamin deficiency and other conditions characterized by a deficiency of compounds necessary for the body.

Helminths are also dangerous because the products of their vital activity have a toxic effect. They can cause severe allergic reactions, destroy beneficial intestinal microflora. Due to the fact that the necessary elements are not stored in the body, but are absorbed by parasites, the body's immune capacity is significantly reduced.

In some cases, massive parasitic infestations lead to the death of the infected person. In countries with a high level of medicine, this is rare, but deaths from ascariasis are recorded annually.

The direct cause of death in helminthiasis is intestinal obstruction, severe pneumonia, suffocation, anaphylactic shock. You can also die from acute purulent cholangitis, cholecystitis or pancreatitis.

Most often, children die for these reasons. In adults, the most dangerous are exacerbations of existing diseases against the background of a decrease in immunity as a result of parasitic invasion.

We can say that the roundworms themselves do not pose a mortal danger to humans, despite the deterioration of the general condition and intoxication with the products of their vital activity.

Prevention of ascariasis

If an infected person has hatched roundworms, this does not mean that he will not be infected again, since the eggs of these worms can remain in the surrounding space. And if you do not take measures to prevent ascariasis, then very soon the person will need treatment again, since the ascaris has again entered the body.

Ascariasis is a disease of dirty hands, therefore, first of all, you need to take care of personal hygiene: wash your hands thoroughly after visiting the toilet and coming from the street, using soap or disinfectants.

All raw vegetables, fruits and herbs must be washed thoroughly. Products undergoing heat treatment, at least for a few minutes at a temperature of at least 55-60 degrees, become safe against infection with ascaris eggs.

Wherever these parasites live, sanitary doctors should conduct educational work on the prevention of parasitic infestation.

Also, the duties of the sanitary services include checking and protecting the soil, sewage, and wastewater. Preventive measures include the fight against insects that can carry eggs and larvae of worms.
