Design outcomes

Primary

MeasureTime frame
Reduction in malaria incidence Year 1 = Month 1, Month 5 and Month 9; Year 2 = Month 1, Month 5 and Month 9; Passive Case Detectio a) The clinical malaria incidence rates, b) the Plasmodium prevalence rates,Cost estimates for MPPT implementation Monthly/Real time Costs spent for intervention and additional MPPT activities

Secondary

MeasureTime frame
