What is leishmaniosis?

leishmaniasis is a parasitic infection that is endemic for many development nations around the world. There are several forms of diseases of leishmaniosis, all of which require medical treatment with antiparasitic drugs. Travelers in developing countries are often recommended that they take steps to avoid infections of leishmaniosis, especially because parasitic protozoans that cause infections to constantly grow more resistant to antiparasitic drugs most commonly used to treat leishmaniasis. These very simple organisms generally live in animals and are picked up by sand flies when these flies feed on animal populations. When sand flies, people bites, people are infected with protozoans. Most cases of leishmaniosis are zoonotic, transmitted from animals to humans, although the disease can also be transmitted from man to humans. The best Way to prevent leishmaniosis disease is to avoid contact with sand flies, using screens and insecticides and avoidingOutside, when the flies are most active, at dawn and dusk.

As soon as the parasite enters the body, the immune system tries to fight it and recognizes it as a foreign attacker. Macrophages are sent to food parasite so that it cannot damage the body, but instead of leishmaniosis, macrophages swelling to their benefit, swelling specialized cells of the immune system and cause their rupture, thus spreading infection in the body. Without treatment, leishmaniosis is not controlled in the body, causing extreme pain and sometimes death.

There are two main forms of leishmaniasis. Skin leishmaniosis causes lesions to appear on the skin, classically with elevated edges and depressive craters. Lees may or may not be painful, depending on the tappage, but are usually red, clotting and very pronounced. The visceral disease of leishmaniosis attacks the internal organs of the body and is fatal without treatment.

In developing countries, access to drugs and treatment of leishmaniosis is very limited. Visceral Leishmaniasis is the main murderer of people in many countries in all Southeast Asia and Africa, because drugs are expensive or unavailable. Some organizations have tried to develop effective and low -cost leishmanium drugs, but many of them have been prevented from lacking in the development of such drugs by pharmaceutical companies, as the pharmaceutical industry would rather invest in high profitable research.
