How can you get infected with ascariasis

Ascariasis is a common parasitic disease caused by worms from the genus roundworms - roundworms. It is often asymptomatic or disguised as other disorders of internal organs, and meanwhile, long-term development of the disease can lead to severe complications. Knowing how infection with ascariasis occurs, you can protect yourself from infection and prevent the consequences of parasitic pathology.

How is ascaris infection

Contact-household method

Fertilized helminth eggs, ready to continue their life cycle, easily get from the environment to household items. People and pets themselves carry them from the street to their homes, along with dust and dirt. The child can come into contact with the larvae of the worms when playing in the sandbox. Flies can transfer helminth eggs from one object of the environment to another.

A person touches the seeded surface with his hands, due to which the parasites pass from the skin to the mucous membrane of the mouth, and from there to the gastrointestinal tract, where the further development of helminths begins.

Fecal-oral method

Adult ascaris mates in the small intestine, after which they leave the human body naturally. Together with the feces, parasites' eggs also enter the soil, which later become a source of infection. With the fecal-oral transmission mechanism, helminths enter the host's body with food that is contaminated with seeded soil.

Ascaris eggs can be in the water, so there are frequent cases of infection when drinking untreated and unboiled liquid from a water supply system or open natural reservoirs.

What products can you get infected through

Most often, roundworms enter the intestines after a person eats fresh vegetables, fruits and berries without thoroughly washing them. The risk of contracting parasites is especially great when eating unpeeled ground cucumbers, tomatoes, peppers, carrots, greens, cabbage, strawberries.

Infection from pets

Human roundworms cannot live in the body of cats and dogs, so people do not get this parasite from pets. However, helminth eggs are often found on the paws or fur of four-legged pets. By petting a dog or cat, you can transfer the roundworm to your hands, and then to the mouth.

Are roundworms transmitted from person to person

The causative agents of ascariasis live only in the human body, so a person is the only source of the disease. However, this does not mean that it is contagious: the patient does not release helminths into the environment along with biological fluids (urine, blood, sperm, saliva), therefore direct transmission of parasites from person to person is impossible.

There is no risk of contact infection, even if fresh parasite eggs are present on the infected person's hands. In order for helminths to begin their development in the host's body, the eggs must mature by laying in warm soil for at least 2 weeks.

While developing in the host's body, the ascaris larvae go through several stages, including migration from the lungs to the stomach through the trachea and epiglottis. Theoretically, parasites can be in a person's saliva for some time, so experts do not exclude the possibility of transmitting helminths during a kiss, although in practice such cases are almost never encountered.

Why re-infection is possible

The human body does not develop immunity to roundworms, so parasites can become infected many times. In this case, not only non-observance of hygiene rules, but also the mechanism of self-infection, plays an important role.

Having the ability to migrate in the human body, roundworms with blood flow from the intestines penetrate the liver and heart, and then the lungs. After that, the larvae enter the trachea, irritate it and cause a cough reflex. During a cough, helminths are thrown into the mouth and swallowed together with saliva, again ending up in the intestines and starting the next life cycle. This is how parasite re-infection occurs.

How to avoid contracting ascariasis

To prevent infection with ascaris, you need to adhere to the following recommendations:

  1. Observe the rules of personal hygiene, wash your hands with soap and water every time before eating, after outside and after contact with animals.
  2. When eating fresh fruits and vegetables, thoroughly cleanse them beforehand.
  3. Drink only boiled water from safe sources.

These measures will significantly reduce the risk of infection, but cannot completely eliminate it. To be sure that there is no helminthic invasion, at least once a year it is necessary to be examined for the presence of parasites in the body.
