Most of us thinks that Hiv/Aids is worst disease out there. Well you may be right, however there are lots of other diseases out that kills faster too, but are not that known;

Leishmaniasis, is a disease caused by protozoan parasites of the genus Leishmania and spread by the bite of certain types of sandflies. The disease can present in three main ways: cutaneous, mucocutaneous, or visceral leishmaniasis. The cutaneous form presents with skin ulcers, while the mucocutaneous form presents with ulcers of the skin, mouth, and nose, and the visceral form starts with skin ulcers and then later presents with fever, low red blood cells, and enlarged spleen and liver.

Infections in humans are caused by more than 20 species of Leishmania. Risk factors include poverty, malnutrition, deforestation, and urbanization. All three types can be diagnosed by seeing the parasites under the microscope.Additionally, visceral disease can be diagnosed by blood tests.

Leishmaniasis can be partly prevented by sleeping under nets treated with . Other measures include spraying insecticides to kill sandflies and treating people with the disease early to prevent further spread.

Rift Valley fever:-Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans. Infection can cause severe disease in both animals and humans. The disease also results in significant economic losses due to death and abortion among RVF-infected livestock.

The majority of human infections result from direct or indirect contact with the blood or organs of infected animals. The virus can be transmitted to humans through the handling of animal tissue during slaughtering or butchering, assisting with animal births, conducting veterinary procedures, or from the disposal of carcasses or fetuses. Certain occupational groups such as herders, farmers, slaughterhouse workers, and veterinarians are therefore at higher risk of infection.

Oropouche fever:- is a tropical viral infection, a zoonosis similar to dengue fever, transmitted by biting midge (species Culicoides paraensis) and mosquitoes from the blood of sloths to humans. It occurs mainly in the Amazonic region, the Caribbean and Panama. The disease is named after the region where it was first described and isolated at the Trinidad Regional Virus Laboratory, in 1955, the Oropouche River in Trinidad and Tobago and is caused by a specific arbovirus, the Oropouche virus (OROV), of the Bunyaviridae family.

The illness has no specific therapy, but usually symptomatic treatment is introduced, by using certain oral analgesic and anti-inflammatory agents, which should be prescribed by a physician, because some of them (such as aspirin) are dangerous because they reduce blood clotting activity and may aggravate the hemorrhagic effects;

The infection is usually self-limiting and complications are rare. Patients usually recover fully with no long term ill effects.
