Visceral Leishmaniasis, also known as kala-azar, is a
vector-borne disease caused by the Leishmania species
complex. In China, there have been a continuous popularity in
hill-type kala-azar endemic areas, mainly in southern Gansu
province and northern Sichuan province. The research aimed
to investigate whether the distribution of human Leishmania
infection showed the characteristics familial aggregation and
spatial aggregation, and provides a reference for the further
control of kala-azar. The binomial distribution goodness of fit
test and SaTScan software were applied for analyzing family
GPS positioning information and laboratory test results of the
family members. It was found that the distribution of human
Leishmania infection corresponded to binomial distribution
and did not conform to the family aggregation and spatial
aggregation. In consideration of the local population and
domestic animals were universally infected and widely
distributed in different families and regions, their role as
reservoir host during the spread of kala-azar should be
emphasized. At the same time, it also implied vector control
could be the key for kala-azar prevention and control in the
hill-type endemic areas in Gansu province, China.
