    Snippet: It revealed that different rearing stages with higher temperature were associated with increased virus spread to dengue in A. abopictus. The rate of dengue-1 virus disseminated infection on A. aegypti was similar to A. abopictus, 39 The temperature change on virus-disseminated infection of mosquito may be species specific. 40, 41 Hence, if sufficient published data are available, temperature-dependent virus dissemination should be incorporated in.....

In general, the dengue transmission pattern in Taiwan is unique compared to other Southeast Asia countries that has been repeated annually: beginning with imported case from Southeast Asia countries in the early summer, spreading out through southern Taiwan in fall, and dying out in winter because of the cold weather with temperatures dropping to below 15°C. The summer weather in southern Taiwan is hot and wet, which provides perfect conditions for vector A. aegypti to thrive and facilitate the dengue transmission. Since annual dengue cases emerge in early summer, the authorities concentrate mainy on physical and chemical interventions (eg, breeding site clean-up and pesticide spray) during summer, dengue transmission is under controlled. 43 If the control measures are not successful, the outbreak then spreads out gradually and peaks around October. Compared with the conditions in summer, the frequency and strength of dengue control measures are reduced during late fall and temperatures drop to below 15°C during late winter, which may lead to a little higher dengue burden in early winter compared to that in late summer.
