Climate change is intrinsically linked to public health and nowadays it taking a toll. A report published by World Bank titled “South Asia’s Hotspots: the impact of temperature and precipitation change on living standard”, says that, more than 75 percent of the population will be adversely affected by rising temperature, and the rate of vector borne and other infectious diseases will increase. We, Bangladeshi people, talk about climate change so often, probably, because we are living in a critical region on the earth where vector-borne diseases are emerging and reemerging. Climate change may lead to a greater spread of infectious diseases, like vector borne diseases, but the efforts to act accordingly are yet to be done. Bangladesh is located in the tropical monsoon region and its climate is characterized by high temperature, heavy rainfall, often excessive humidity, and fairly marked seasonal variations. Consequently, we saw an increasing rate of vector borne diseases and, according to weather experts, it is known as effect of climate variability. This study suggests that temperature and rainfall are significantly associated with chikungunya incidence in Bangladesh. Based on the findings, we conclude that the climate change plays a critical role in the transmission of chikungunya virus.
