Abstract
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.
