Why Are Multiple Strategies Needed to Control Malaria?
* Multiple strategies against malaria are needed because there are numerous species of vectors and four species ofPlasmodium. * Some populations of Plasmodium, especially Plasmodium falciparum, are resistant to drugs, so alternative drugs need to be used. * Research needs to be done on new drugs as a "reserve weapon" for future cases of drug resistance. Unfortunately, drug resistance is more common in malaria caused by Plasmodium falciparum, the most dangerous type of malaria, than in the other three species. * Some populations of mosquitoes have developed resistance to certain insecticides. This resistance may be of varying degrees. It is important that alternative insecticides be available for breaking human-vector contact. * Dwellings are constructed differently in different parts of the world, and thus different strategies may be appropriate in different places.Please Name Some Specific Strategies for Malaria Control: * Screening:Screening of Dwellings to Prevent Malaria Mosquitoes from Entering and Biting the People Inside. Screening is a positive development measure. Screening of buildings also improves people's lives in other ways i.e. keeping flies out of homes and cafes. Where it is possible [i.e. buildings have four walls] to put screens on windows and screen doors on doors, screening should be encouraged. Screening is also a useful adjunct to use of a treated bednet or residual treatment of walls because it reduces the number of malaria mosquitoes entering and leaving the building and increases the odds that Anopheles mosquitoes that get into the building will be exposed to the treated bednet or residual treatment. * Source reduction: This is possible in some conditions but very difficult in other conditions. Malaria mosquitoes breed in many different locations. Source reduction is particularly useful if mosquitoes are breeding in man-made containers such as water tanks or at...
