Impacts of exposure to ambient temperature on burden of disease: a systematic review of epidemiological evidence

Heatwaves and dengue outbreaks in Hanoi, Vietnam: New evidence on early warning

“…So far, few studies have assessed temperature-related dengue burden, measured as attributable fraction, attributable number or disability-adjusted life years [30]. Burden of disease assessment considers health-related information such as relative risk and prevalence of exposure among population, which is different from the widely used risk assessment like relative risk or odds ratio that is inadequate to reflect the magnitude of health impacts of temperature [30].…”

Using a widely used approach in the field of climate change and burden of disease [30,34], we found that temperature was responsible for a large number of dengue cases, with more temperature-related cases from large outbreaks.…”

“…Burden of disease assessment considers health-related information such as relative risk and prevalence of exposure among population, which is different from the widely used risk assessment like relative risk or odds ratio that is inadequate to reflect the magnitude of health impacts of temperature [30]. Using a widely used approach in the field of climate change and burden of disease [30,34], we found that temperature was responsible for a large number of dengue cases, with more temperature-related cases from large outbreaks. In other words, temperature may play an important role in affecting dengue outbreaks, especially the large outbreaks.…”

“…Cost-effectiveness of developing and implementing early warning system that incorporates the short-term effects of temperature is a pressing future research area. Heatwave weather is a well-recognised risk factors for health, such as increasing total, cardiovascular and respiratory mortality [21,30]. There is also growing attention to heatwaves and vector-borne diseases [16][17][18].…”

“…In the second stage, we estimated the extent to which dengue cases were attributable to temperature following the method in our previous work [21,30]. Relevant estimates were reported as attributable fraction and attributable number.…”
