Country /regionreference | Years of study | Measure of reduction | Reported reduction | Reported Reasons |
|---|---|---|---|---|
Sub-Saharan Africa1 | 1985 to 1999; 2000 to 2007 | Parasite prevalence abstracted from over 2,000 sources | 15% (average) reduction | No reason given |
Coastal Kenya2 | 1999 to 2007 | Malaria specific hospital admissions | 63%, 53% and 28% reduction in 3 district hospitals | Malaria control interventions |
Ifakara, Tanzania3 | 1995 to 2000 | Incidence of malaria in < 5 year old children | Reduced from 0.8 to 0.43 episodes per child per year | Economic improvements, liberalisation of health sector and malaria control interventions |
Zanzibar, Tanzania4 | 2003 to 2006 | Parasite prevalence | 97% reduction | Artemisinin Combination Therapy and Insecticide Treated Nets |
