Abstract:
Objective Characteristics and tendency of mosquito and major mosquito-borne diseases (including epidemic encephalitis B and malaria) were analyzed in the Three Gorges Reservoir Area from 1997 to 2008. Methods Information on surveillance data related to mosquito-borne infectious diseases and on mosquito density and category, from 1997 to 2008 was collected from Health Surveillance System in Three Gorges Reservoir Area. Data regarding meteorological factors and construction of Three Gorges Reservoir was also collected. Pearson and Poisson models were used. Results From 1997 to 2008, in the Three Gorges Reservoir Area, the incidence rates of epidemic encephalitis B and malaria were decreasing. Positive correlations were shown between indoor and outdoor mosquito density as well with temperature with coefficient as 0.281 and 0.355 respectively. Correlations of mosquito-borne diseases with indoor and outdoor mosquito density were positive, with correlation coefficient as 0.340 and 0.328 respectively. Conclusion There seemed lack of evidence to prove that negative influences had occurred on the incidence of mosquito-borne infectious diseases or the mosquito density after the Three Gorges Reservoir water storage came into being in 2003, however, long-time surveillance program needs to be carried out to gather information on this issue.
