The global estimates for increases in malaria and dengue deaths  are approximately 32,700 and 280 additional deaths, respectively, in 2050 under the medium-to-high emissions scenario . Among these additional deaths, 9,300 and 200 deaths, respectively, are projected to occur in South Asia. The population at risk of malaria infection is estimated to increase by 134 million by 2030 in South Asia under the medium-to- high emissions scenario, considering socioeconomic development. If no actions are taken, malaria incidence in northern China is projected to increase by 69-182% by 2050 . Another study suggested a decrease in climate suitability for malaria in northern and eastern India, southern Myanmar, southern Thailand, the Malaysia border region, Cambodia, eastern Borneo and Indonesia by 2050 . By contrast, climate suitability for malaria is projected to increase in the southern and southeast mainland of China and Taiwan, Province of China .
