PREY MONG KOL, CAMBODIA - JULY 18:  Yonta ,6, rests with her sister Montra,3, and brother  Leakhena, 4months under a mosquito bed net keeping dry from the monsoon rain July 18, 2010 in Prey Mong kol village in Pailin province. Part of the great success of controlling the malaria is due to the distribution by National Malaria center (CNM)  and WHO of the long lasting mosquito nets that also contain the insecticide embedded into the net causing the insect to die upon contact. According to WHO,  around 3,000 people from various villages have been tested so far in an area where resistance to artemisinin surfaced, which is the most effective ingredient vital to all anti-malarial drugs used throughout the world, especially in fighting the more lethal Falciparum malaria. The results are proving that the resistant malaria has almost disappeared from the area. (Photo by Paula Bronstein/Getty Images)
