Dengue Fever epidemiological status and relationship with meteorological variables in Guangzhou, Southern China, 2007-2012 / 生物医学与环境科学（英文）

ABSTRACT

Ecological methodology plus negative binomial regression were used to identify dengue fever (DF) epidemiological status and its relationship with meteorological variables. From 2007 to 2012, annual incidence rate of DF in Guangzhou was 0.33, 0.11, 0.15, 0.64, 0.45, and 1.34 (per 100 00) respectively, showing an increasing trend. Each 1° C rise of temperature corresponded to an increase of 10.23% (95% Cl 7.68% to 12.83%) in the monthly number of DF cases, whereas 1 hPa rise of atmospheric pressure corresponded to a decrease in the number of cases by 5.14% (95% Cl 7.10%-3.14%). Likewise, each one meter per second rise in wind velocity led to an increase by 43.80% or 107.53%, and one percent rise of relative humidity led to an increase by 2.04% or 2.19%.
