|
|
|
the world population growth rate is increasing very rapidly
|
|
|
warmer temperatures allow for disease-carrying insects to survive in areas that were once too cold.
|
|
|
disease-carrying microbes are migrating more rapidly into the tropics and subtropics
|
|
|
the rain forests are rapidly expanding to cover more of Earth’s surface
|
|
|
techniques and efforts to combat infectious diseases have not been successful globally
|
Detailed explanation-1: -Changes in climate influence many infectious diseases. Changes in weather patterns that favor the conditions needed by a pathogen―particularly in terms of average temperature, precipitation, and relative humidity―will positively affect its ability to survive and spread.
Detailed explanation-2: -The March 2022 report from the Intergovernmental Panel on Climate Change (IPCC) warned that without swift climate action we will see an escalation of infectious diseases. They will spread to new regions (and may decline in some endemic areas). They’ll surge in areas where they were previously under control.
Detailed explanation-3: -Increased temperature could increase dengue risk by increasing the rate of mosquito development and reducing virus incubation time in areas where the vector presently exists, thereby increasing the rate of transmission [13–16].
Detailed explanation-4: -Warmer temperatures can increase the geographic spread of where vectors – like mosquitoes and ticks – can survive and breed. Increased rainfall can increase the amount of standing water, creating more breeding areas for many vectors.
