Hookworm Disease

Hookworm infection is the presence of hookworms in the intestines of humans are very common, especially in tropical climates. some hookworms do not usually cause any symptoms or disease in the human host, as large numbers of hookworm disease caused by worms: hookworm, however, one difference between hookworm infection and disease away.

In order to understand the symptoms of hookworm disease, & # 39; s important to understand how hookworm infection (hookworm life cycle). You do not catch this parasite through direct contact with another infected person. Instead, pick it up when the skin comes into contact with soil contaminated with the stool of an infected person. Hookworm larvae, the stage that infects people are present in warm moist soil where an infected person outside defecate on the floor.

Hookworm larvae do the best loose soil that is rich in organic material. Not good for dry sandy soils or soils that at a lot of clay, and is not formed below about 17 degrees Celsius. Freezing kills them. Because they are so sensitive to cold, hookworms are basically limited to warm climates and warm micro-climate inside the ground like mines. Hookworm infection does not occur in the northern and southern temperate climates.

When human skin is in contact with hookworm larvae live in the soil, the larvae on the skin and begins to wander. If there are a lot of them, you may have a skin reaction and inflammation, which penetrate into the blood vessels. The body & # 39; and the immune system that causes inflammation, as he attempts to kill the larvae. Hookworm Infection end of this stage, when the immune system is successful; larvae that survive get carried away in the heart and lungs. In the lung, the large number of larvae cause the first solid indication hookworm disease.

Hookworm larvae break out of blood vessels in the alveoli of the lungs (the bag-like spaces filled with air when you breathe). Each larva causes breaking through a little bleeding from the lungs. Some larvae do not even realize it, and at the same time a large number of outbreaks are rare, but if it does happen, the pneumonia-like illness occurs. The lungs, the larvae travel up the trachea to the throat and then down through the stomach to the intestine, where grow into adult worms. At this stage, it can cause diarrhea and abdominal pain.

Again, a few dozen hookworms in the intestines of a light infection causes no symptoms; 100 worms, hookworm causes mild disease, while hundreds of serious health threat to the host, and thousands can be killed. Severe symptoms of chronic (ongoing) hookworm disease include growth, anemia, weakness, fatigue, lack of protein, and decreased learning ability. In regions where people are already struggling with nutritional deficiencies, hookworm disease, high incidence of serious consequences for society as a whole.
