Abstract:

Objective To understand the natural focus disease dynamics among people living in the surveillance sites of Three Gorges Reservoir in Yichang city,to provide timely measures for disease control and prevention. Methods Continuously collecting and analyzing 2003-2015 surveillance natural focus disease incidence data, crowd serological data, and rodents monitoring data. Results From 2003 to 2015, Three Gorges Reservoir of Hubei Yichang section reported leptospirosis, malaria, rabies each 1 case, no plague, epidemic hemorrhagic fever, and other natural focus disease cases reported. Serological surveillance results showed that the crowd epidemic hemorrhagic fever and leptospirosis antibody positive rate were 2.22%, 14.12% respectively. Indoor rodents' density declined after rising first, outdoor rodents' density was on the decline in volatility trends. Renal leptospirosis and pulmonary hemorrhagic fever positive rate were 3.49%, 0.35% respectively.
