In a warming world, viruses and their mosquito vectors are fast acquiring traits to gang up on humans

·        Aedes mosquitoes are originally found in tropical and subtropical parts of the globe.

·        Though most serious diseases such as dengue, chikungunya, yellow fever and zika are transmitted by just two species — Aedesaegypti and Aedesalbopictus — these are fast emerging throughout the world as a public health threat.

·        Aaegypti is native to sub-Saharan Africa, and in its native environment it lives in tree holes and small pools of water and bites non-human primates.

·        Similarly, Aalbopictus is native to tropical southeast Asia, where it was originally a forest species that fed on wild animals.

·        While human-made conditions have created it simple for the mosquitoes to meet larger areas, global {warming|heating|warming} has any aided in their proliferation as warm and wet environments are wonderful places for mosquitoes to breed.

·        Aaegypti is heat-tolerant and also the A albopictus is heat-limited.
