I’ve already answered a similar question on how you find different treatments for Malaria http://ias.im/44.40
In addition to that answer there are lots of scientists all over the world trying to find different ways of treating Malaria as we need as many possible cures as we can find. How long does it take? Well if tomorrow I made a breakthrough in my research tomorrow it would take 15-20 years and the work of hundreds more scientists before that discovery became a new treatment.
