Abstract– Leishmaniasis is a prevalent protozoan infection in many parts of the tropical and subtropical world, causing a wide spectrum of human disease ranging from the life threatening Kala azar to the disfiguring mucosal and cutaneous forms of the disease. Kala azar is a severe form of disease that is nearly always fatal in the majority of untreated cases and ranked only next to malaria among human protozoan diseases. The World Health Organization (WHO) is included Kala azar in the list of neglected tropical diseases, with among the poorest a major impact and continues to be a major problems and economic disparity across the world. However, despite the apparent study on localization of Kala azar in the endemic regions of Bihar, the role of distribution of Kala azar in different age groups and sex category has remains unexplored. Herein, we investigate to attempt the correlation of Kala azar between age and sex groups and their distribution in four districts of Bihar.
