Disease Burden Growing as Vector Insects Adapt to Climate Change

Dry drains will reduce the numbers of mosquitoes breeding, but now the Aedes aegypti mosquito is going underground to breed underground in available water and flying to feed.

The revelation also made it clear that climate change would force scientists and environmental health professionals to spend more time studying new breeding cycles and finding new control techniques for vector insects.“Globally, we predict that over 2.17 billion people live in areas that are environmentally suitable for ZIKV transmission." --Dr. Moritz KraemarJump to March 31, 2017 when the UWI and the government of Jamaica opened the new Mosquito Control and Research Unit at the Mona Campus in Kingston, to investigate new ways to manage and eradicate mosquitoes. Its existence is an acknowledgement that the region is looking for improved management and control strategies.Agard was reporting on a study by the late Dave Chadee, a co-author on the IPCC Fifth Assessment Report an...
