To ensure health security under unavoidable climate change in the 1.5°C–2°C global warming pathway has already made Asia’sstatus challenging owing to the disruption of the functioning ecosystem and manifold uncertainties.In their recent report, titled “A Region at Risk: The Human Dimensions of Climate Change in Asia and the Pacific,” has highlighted the death rates, temperature rise, and heatwaves, the pattern of rainfall, record number of flooding, agriculture biodiversity would lead to drastic changes in the region’s fate.Therefore, these key indicators demand a focus on the status of health hazards in this region to realize that overall health concerns are greatly affected by the adverse effects of climate change. According to the World Health Organization (WHO), about 150 000 deaths occur worldwide in low-income countries every year owing to the adverse effects of climate change, crop failure and malnutrition, floods, diarrheal diseases and malaria, where India, Pakistan, ...

Climate change creates new uncertainties for human exposure to  vector-borne diseases , and this is especially true for dengue fever and malaria. The changing weather patterns affect the development and dynamics of the disease vectors and the pathogens they carry. The range of Aedes mosquitos is changing, with dengue fever and the chikungunya virus emerging in areas where they were previously unknown. There is evidence that the geographic range of ticks and mosquitoes that carry disease has changed in response to climate change. As temperatures warm, mosquitoes and other warm-weather  vectors  can move into higher altitudes and new regions farther from the equator. Increased rainfall, flooding, and humidity creates more viable areas for vector breeding and allows breeding to occur more quickly, as eggs hatch faster in hotter climates. According to  data from the World Health Organization , deaths related to vector-borne diseases such as malaria and dengue...
