Malaria is found in the tropics and subtropics, in equatorial areas. The highest risk areas is Sub Saharan Africa, and the Amazon Jungle of South America, The malaria spreading mosquito bites between dusk and dawn.

Worryingly, in many places the insects are fast becoming immune to anti-malaria preparations. Scientists across the world are doing their best to dream up innovative new ways to halt the disease, including making key changes to the creatures’ DNA and even releasing millions of infertile male mosquitoes into the wild. Global warming means malaria-carrying insects are spreading into cooler regions, so protection is more important than ever. But there’s some hope that a good malaria vaccine is finally on the cards, with exciting new developments bring made..
