The Global Malaria Control Strategy was created with the objective of preventing mortality and reducing morditity, and social and economic loss due to disease through the progressive improvement and strengthening of local and national capabilities. The four basic technical elements of the Strategy are: 1) to provide early diagnosis and prompt treatment; 2) to plan and implement selective and sustainable preventive measures, including vector control; 3) to detect early, contain or prevent epidemics; and 4) to strengthen local capacities in basic and applied research to permit and promote the regular assessment of a country's malaria situation, in particular the ecological, social and economic determinants of the disease.
