from black-water fever. Hyper-endemic areas may be defined as
regions in which the endemic malarial index is maintained at 50 per
cent. or over throughout the year. The Duars is such an area and
there are others to be found in various parts of India. The distribu-
tion of black-water fever in India is the same as that of hyper-ende-
mic malaria. But areas in India at present not hyper-endemic may
become so as the result of labour aggregation, and we have good rea-
sons for believing that new foci of black-water fever will result from
time to time as circumstances lead to the formation of new hyper-
endemic areas.
The question of black-water fever in a district, therefore, resolves
itself into one of anti-malarial sanitation especially directed to the
prevention of the disease among Europeans, a subject we have \ill\
with in the last chapter.
