How is climate change causing the emergence of zoonotic and vector-borne in new human populations?
What will be an ideal response?
Answer: Climate change may be changing the range of certain animals and insects that carry diseases that can infect human populations. This can be very serious because when a new disease is introduced into a population, that population will have no herd immunity for the disease and it could spread rapidly. Examples are the movement of vampire bats north from Mexico into the United States. Vampire bats can carry rabies and can infect humans by biting them. Another example is that the increased temperature and rainfall caused by climate change could expand the range of Aedes aegypti, the mosquito which carries dengue fever, yellow fever, and malaria.
