Parasitic infections

Parasites are very harmful to human health. Therefore, when drinking water, you cannot choose raw water, otherwise it is easy for parasites to invade the body and cause serious damage to the body. So what is parasitic infection? Its infection poses a great threat to all aspects of the human body, and after such a situation occurs, the body will also have obvious manifestations, so you should pay attention to this.

Many people don’t know much about parasitic infections, so when they occur, they don’t know how to deal with them. Parasitic infections will cause the patient to lose nutrients, deteriorate the patient’s physical fitness, and cause the body to gradually become thin.

Parasitic infections:

Parasitic infections are common in Africa, Asia, and Central and South America but are rare in other regions. Travelers from industrialized countries to endemic areas can often reduce the risk of infection by observing guidelines for eating and swimming hygiene and taking simple measures to reduce exposure. Travellers from endemic countries are sometimes less likely to spread parasitic diseases in developed countries because the environmental conditions required for the transmission of many parasitic diseases, i.e. vectors and intermediate hosts, are usually absent in industrialised countries. However, transmission of imported infection may still occur through the fecal-oral route, blood transfusion, organ transplantation or local suitable media.

Parasites live in the host's cells, tissues or cavities, causing a series of damages. This is not only seen in protozoa and adult worms, but also in migrating larvae. Their effects on the host are multifaceted.

1. Taking away nutrition

The substances required for parasites to grow, develop and reproduce in the host's body mainly come from the host. The more parasites there are, the more nutrients they take away. For example, ascarids and red worms parasitize in the intestines, stealing a large amount of nutrients and affecting the intestinal absorption function, causing malnutrition in the host; hookworms attach to the intestinal wall and absorb a large amount of blood, which can cause anemia in the host.

(II) Mechanical injury

Parasites can cause damage or compression to the area where they parasitize and its surrounding tissues and organs. This harm is quite serious when some parasites are large in size and in large numbers. For example, when there are too many roundworms, they can twist into a ball and cause intestinal obstruction. Echinococcus larvae parasitize in the liver. There are no obvious symptoms at first, but they gradually grow larger and compress the liver tissue and other organs in the abdominal cavity, causing obvious compression symptoms. In addition, the migration of larvae in the host body can cause serious damage. For example, when Ascaris larvae migrate in the lungs, they can penetrate the capillaries in the alveolar wall and cause bleeding.

Through the above introduction, we have a good understanding of parasitic infections, so after such problems occur, we also know how to improve them. However, it should be noted that the treatment of parasitic infections must be carried out in a regular hospital, which will be of great help in improving the disease.
