Abstract:

Objective To assess the risk of vector-borne diseases in Tianjin, China by risk recognition and assessment methods and to prevent the incidence and prevalence of vector-borne diseases. Methods The risk of vector-borne diseases was graded by comprehensively analyzing the probability and consequence of risk events. Results In Tianjin, the density of rodents decreased year by year from 2008 to 2012 (0.64%-0.19%); the captured rodents had a negative indirect hemagglutination test for plague F1 antibody; hantavirus was detected in 0.85% of rodents in 2011 but not in 2012. The mean densities of mosquitoes were 14.11, 15.04, 16.64, 18.82, and 11.09 mosquitoes/lamp·h; no pathogens were detected in mosquitoes in recent years. In Tianjin, the prevalence of mosquito-borne diseases, such as malaria, dengue fever, and Japanese encephalitis, and rodent-borne diseases, such as plague and hemorrhagic fever with renal syndrome, were at low risk. Conclusion Certain risk of vector-borne diseases does exist in Tianjin. In order to prevent and control the incidence and prevalence of vector-borne diseases, it is necessary to strengthen the surveillance of vector density and pathogens carried by main vectors, enhance the knowledge among residents, and make good preparation for the potential introduction and disposal of vector-borne pathogens.
