It was very effective, had few side effects, and, most importantly, was very inexpensive.

Part of the upturn in this lethal disease was due to poverty. Develop- ing countries –especially in sub-Saharan Africa – did not have the resources to provide their people with needed medical care and preventive measures such as bed netting. But, there are many other environmental factors that are increasing the threat of malaria and other diseases carried by animals and Animals and insects live in habitats that are suited for them.

Insects and other animals will leave a place that no longer gives them the right tem- perature range or the right geographic feature such as a forest. And they will expand their ranges to include areas that now feature their ―must-haves.‖ When they move to these ―other‖ areas vector animals and insects (those that carry diseases) bring their diseases with them. A whole population—the existing residents of that ―other‖ area— And this population hasn’t had a chance to build immunity to the To them, their new neighbors are a deadly group. That’s what’s happening now with malaria. It’s been getting hotter in certain areas of the world, if only by a small fraction of a degree. But that small fraction is enough for the mosquitoes to expand their The lethal disease of malaria is on the move.
