Different Type of Diseases

Ebola hemorrhagic fever (EHF) is a viral hemorrhagic fever and one of the most virulent viral diseases known to humankind. The Ebola virus was first identified in the western equatorial province of Sudan and in a nearby region of Zaire in 1976 after significant epidemics in Nzara, southern Sudan and Yambuku, northern Zaire. The Ebola virus is transmitted by direct contact with the blood, body fluids and tissues of infected person. Transmission of the Ebola virus has also occurred by handling sick or dead infected wild animals (chimpanzees, gorillas, monkeys, forest antelope, fruit bats).

Leishmaniasis is caused by parasitic protozoa of the genus Leishmania. Humans are infected via the bite of phlebotomize sandflies, which breed in forest areas, caves, or the burrows of small rodents. Leishmaniasis is found in some parts of Asia, the Middle East, Africa (particularly in the tropical region and North Africa and southern Europe. The skins sore of cutaneous leishmaniasis usually heals on own, without a treatment. Mucosal leishmaniasis might not be noticed until years after the original sores healed. The best way to prevent mucosal leishmaniasis is to ensure adequate treatment of the cutaneous infection. If not treated, severe cases of visceral leishmaniasis typically are fatal. The symptoms and signs of cutaneous leishmaniasis have one or more sores on their skin. The sores can change in size and appearance over time. The sores may start out as bumps or lumps and may end up as ulcers, with a raised edge and central crater and skin ulcers may be covered by scab or crust. The symptoms and signs of visceral leishamaniasis have fever, weight loss, enlargement (swelling) of the spleen and liver, and abnormal blood test. People may have low blood counts, including a low red blood cell count, a low white blood cell count, and a low platelet count.
