Parasitism is a form of intercourse between two organisms. The parasite settles in the body of its host and uses its nutrients. Unfortunately, many of us do not realize that it can be the host of another organism. The World Health Organization warns that parasites and worms are one of the most common causes of diseases that are a direct threat to people. Up to 90 percent World population can be parasite carriers.
Internal parasites get into the body mainly due to improper hygiene that exposes us to their presence. Before eating, wash your hands thoroughly and wash the vegetables and fruits. If you often eat uncooked meat (such as tartare) or raw fish (for example sushi), we are more exposed to the occurrence of parasites and worms in our body. Unfortunately, we can infect them with water. We should not drink uncooked water from uncleaned tanks. It is also not advisable to bathe in dirty, wild lakes.
Parasites live in different parts of the human body. Because of this, their occurrence is associated with many symptoms. A man in full strength may not even notice the fact that he is a carrier of parasites. The consequences are more serious in the case of people with reduced immunity or when the parasite is living in the body for a long time and begins to reproduce. One of the first symptoms is unprecedented hardening and diarrhea. This applies mainly to parasites that live in human intestines. Carriers also have gas, flatulence and inflammation of the irritable bowel. Parasites that move to the muscles and joints can cause sudden pain in these places. Symptoms can also be severe anemia. We should also pay attention to sudden allergies or any skin changes. The presence of parasites also affects the well-being of the host. Any depression, nervousness or chronic fatigue can be caused by other organisms in our bodies.
Nematodes belong to those parasites that very often cause disease. In the group of the highest risk there are mainly children – it is difficult to guard them so that they do not put dirty hands in their mouths, eat anything raised from the floor or grass, and do not lick objects. However, parasitic diseases do not only affect children – adults also get very sick very often. How does the infection occur, what are its symptoms, and how should you protect yourself against infection?
Nematodes belong to the roundworms, primarily living in the aquatic environment. The vast majority of them are parasites attacking animals and plants. However, it is very easy to get infected with them and it can happen everywhere. The ideal conditions to gain a parasite in your body is inadequate hygiene – this is particularly important in poor environments, living in inadequate sanitation, but also among children who unfortunately do not realize how important it is to avoid direct threats of this type, for example when playing in the yard. The group of nematodes includes parasites such as pinworms – they are one of the most widespread parasites that occur most often in children. While pinworms are relatively easy to cure, although they require regularity and strict adherence to some rigors, the infection with tortoises or human glades is more dangerous.
The most common infection with parasitic nematodes is due to the lack of proper hygiene. If before eating fruits and vegetables you do not wash them thoroughly, or eat a lot of meat (especially bought in different places), the risk of getting infected with any of the parasites is considerable. The most common are
Pinworms - this type of parasite nestles in the large intestine, often also in the caecum. Males die after fertilizing females, and these escape outside the human body to lay eggs. This movement causes symptoms in the form of itching around the anus. Reflex scratching puts eggs on your hands, from where it's easy to spread them into everyday objects and other people. Oats are most common in children, but one infected person is enough for the whole family to fall ill instantly. Possession of pinworms does not pose a direct threat to health, but if treatment is neglected - the consequences may lead to disturbances.
Human worm - this parasite inhabits the human intestine. He loses his walls and gets out of the intestine, moving to the bloodstream, and then to the alveoli, where he lays. Then he goes to the larynx, through the bronchi and trachea, causing coughing. Human worm larvae get out of the body through faeces and are able to infect even for several years.
Twisted hair is the most dangerous variation among human parasites from the group of nematodes. It is the direct cause of the disease, which is trichinosis - and this can even cause death. Twisted hair is small - from 1.4 mm (male) to 4 mm (female). The most common way of infection is meat intake, on which the Trichinella larvae live. After getting into the stomach, they get out of the capsules and migrate to the small intestine, where they can reproduce after only 2 days. From there, they get into the bloodstream, and then into the striated muscles, where they can live for several decades.
The symptoms of nematode presence depend on the specific parasite that has been implanted in the body. The most common are pinworms, which cause increased pruritus around the anus, increasing their intensity in the evenings and at night. It is accompanied by problems with concentration and irritability, weakness and weight loss. Glycene, caused by human worms, can be completely asymptomatic. Often, however, it makes itself felt by general weakness, hyperactivity, facial swelling, dizziness and allergic reactions. In turn, the most severe trichinosis alerts you to a high fever, digestive problems: abdominal pain and diarrhea, as well as muscle pains and facial swelling.
