2.4. Data sources and analysis
Mosquito density and dengue incidence are the two important
indicators for risk evaluation. BI of Aedes before supervision was
the average BI value throughout September attribution by the local
CDC, and BI after supervision came from the rapid detection work
by China CDC. Biting index came only from the rapid detection by
China CDC (Table 1), and dengue incidence data from the online
National Notifiable Infectious Disease Reporting Information System
of China CDC (Lai et al., 2015).
We contrast the BI value in September with that get from the
rapid detection (Fig. 2), paired sample t-test by SPSS19.0. We give
the epidemic curves of dengue in 2014 for comparing dengue incidence
cases during the measures implementing (Fig. 1). Data was
entered and analyzed by Microsoft Excel 2007.
