<prompt> True about kala-azar -More common in female than maleEliminated from IndiaNon-human reservoirs are presentAll  <response>: Ans. is c i.e., Non-human reservoirs are present o Males are affected twice as often as famales. o The incubation period in man is quite variable, generally 1 to 4 months; range is 10 days to 2 years. o Kala-azar is mostly confined to plains, it does not occur in altitudes over 2000 feet 600 metres. o It has been known to occur epidemically endemically in well-defined areas in the eastern sector of the country. Presently the endemic states are Bihar, Jharkhand, Uttar Pradesh West Bengal. o Reservoirs of Infection Although Indian Kala-azar is non-zoonotic but in general, it has animal reservoir i.e., non-human reservoir. There is a variety of animal reservoirs e.g., dogs, jackals, foxes, rodents other mammals. Indian kala-azar is considered to be a non-zoonotic infection with man as the sole reservoir. This assumption is based largely on the absence of evidences.
