Given the current outbreak of Dengue Fever in Pakistan (mostly in Punjab at the moment), the following might be of interest.
Interesting article in Science Daily,
It may be possible to eliminate the deadly dengue fever by infecting mosquitoes with a bacterium called Wolbachia that prevents the mosquitoes from transmitting the dengue virus to humans. A new mathematical model, developed by Nick Barton (Institute of Science and Technology, Austria) and Michael Turelli (University of California, Davis), may be helpful in getting the bacteria established in mosquito populations.
