Climate Change May Shift Risks of Mosquito-borne Diseases

Asher Jones

   More dengue, less malaria. That may be the future in parts of Africa on
   a warming planet, depending on where you live.

   [1]New research saysit's all about which mosquitoes will thrive. And
   the methods to control one don't necessarily work on the other.

   The mosquito that spreads malaria prefers relatively cool temperatures
   of 25 degrees Celsius (77 degrees Fahrenheit). The dengue mosquito does
   best at 29 degrees Celsius (84.2 degrees Fahrenheit).

   Because of this difference in optimal temperatures, "We would actually
   predict that climate change might have opposing effects [on disease
   transmission]," said Erin Mordecai, assistant professor of biology at
   Stanford University and lead author on the study. "Climate change might
   make it less suitable for malaria to be transmitted but more suitable
   for dengue to be transmitted."
