Dengue is a mosquito-borne tropical disease caused
by one of the four serotypes of dengue virus. There are about 2,5
billion people living in endemic areas. The potential influence
of environmental and climatic factors on the transmission of
mosquito-borne diseases are expected in many situations but the
exact real influences of climatic variables remain uncertain in
most of the cases. In the present study, we applied the Granger
causality to analyze the relation between climatic variables and
the monthly incidences of dengue syndromes in Vietnam for 64
provinces from 1994 to 2010. The experimental results shows a
close relationship between climatic factors and dengue incidence
in each province and their neighbourhoods.
