Malaria will become deadlier

Stephen Rich : evolutionary biologist
Since mosquitoes are residing with us, the parasites found on those insects, like the Plasmodium species that cause malaria, are also living with us. Our close quarters with these parasites will guide their evolution over the next few centuries. Because we've made it easy for the malarial parasite to find us and its mosquito hosts, nature isn't selecting for the 'finding host' genes as strongly anymore. Now, the pressure is on other traits the parasite needs to survive, like quickly reproducing inside of our cells, which will probably make the parasite deadlier.
