mosquitoes and aquatic snails. Farmers seem to concentrate on irrigation water management rather than on drainage management. Moreover, there is often a lack of adequate domestic water supplies and sanitation facilities. Thus, drainage canals or drainage water treatment and disposal facilities are often misused for washing, drinking and uncontrolled disposal of human excreta or other waste by the poorest and, thus, most vulnerable social groups. In this way, drainage water contributes to disease transmission [ WHO Manuel 2001]. 3. Describe at least one possible community-based public health or environmental stewardship intervention that is used or could be used to prevent or reduce this problem. Vector control is the main way to reduce malaria transmission at the community level. It is the only intervention that can reduce malaria transmission from very high levels to close to zero. Indoor residual spraying (IRS) with insecticides is a powerful way to rapidly reduce malaria transmission. Antimalarial medicines can also be used to prevent malaria [ Utzinger J, Tozan Y, and Singer BH]. References: Cibulskis RE et al. Estimating trends in the burden of malaria. American Journal of Tropical Medicine and Hygiene , 2007, 77 (6):133–137. WHO: Manual on Environmental Management for Mosquito Control: with special emphasis on malaria vectors .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
