In 2014, China experienced the most severe dengue outbreak
since it became a notifiable disease on 1 September 1989 (Lai et al.,
2015). A total of 47,056 laboratory and clinical confirmed dengue
cases with six deaths were reported in mainland China in 2014,
96.1% of which were from Guangdong province and 72.2% from
Guangzhou city (Lai et al., 2015). This dengue outbreak in south
Chinamight be partly attributed to inadequate enforcement ofintegrated
vector management (IVM) at the early stage.
