Taming the mosquito menace

By John J. Cohrssen and Henry i. miller

Mosquito-borne diseases kill millions of people annually, and cause suffering for many more. In 2012, there were an estimated 207 million cases of malaria, leading to some 627,000 deaths. Dengue fever is a leading cause of illness and death in the tropics and subtropics, with as many as 100 million people infected each year. And there are an estimated 200,000 cases of yellow fever annually, leading to 30,000 deaths worldwide.
