Scientists all over the world are racing to stop the Zika virus epidemic. One solution being tested in Brazil is to release hundreds of thousands of male mosquitoes every day that have been engineered with a “self-destruct” gene. Female mosquitoes are the only ones who bite, so if they mate with these genetically engineered males, all offspring dies before they can spread Zika. This is projected to cut the number of disease-spreading mosquitoes by 70-80 percent. But not everyone agrees that this is the best solution. Engineering the mosquito population may allow other diseases to spread. Other solutions include sterilizing the mosquitoes or using bacteria. Listen and debate what your students think are the best ways to fight the Zika epidemic.
