What can the residents of malaria endemic countries do to protect themselves against malaria?
The incidence of malaria may vary substantially between adjacent communities and within an individual community, even in areas of high malaria transmission. Analysis of the factors responsible for these local variations in the incidence of malaria may identify potential control measures. Factors shown to be associated with local protection against malaria in some situations include house position, house design, the use of insect repellents and mechanical barriers such as bednets and curtains. The efficacy of insecticide treated nets and curtains in preventing mortality and morbidity from malaria, at least in the short-term, has been demonstrated convincingly. However, other measures of personal protection have not been evaluated in large trials which have clinical malaria as their endpoint. Such trials are needed to see if new malaria control tools can be identified that will assist current international efforts to improve malaria control, especially in Africa. The millions of non-immune travellers who visit malaria endemic areas each year need to protect themselves against malaria and the ways in which they can do this most effectively have been studied extensively. However, less attention has been paid to the local population of malaria endemic areas. What steps can they adopt to provide personal protection against malaria and how effective are these measures? Clues to which measures might be effective can come from study of the reasons for local variations in the incidence of malaria.
