AL: $0.31 - 1.23 depending on child weight

AQ + SP: $0.125

DP: $0.741

Dihydroartemisinin Piperaquine (DP) is an alternative ACT while Amodiaquine Sulphadoxine-Pyrimethamine (AQ + SP) is a cheap alternative that might be used in an area where SP is still effective.

Treatment Follow Up

Treatment follow up carried out by nurses as described

Unsupervised treatment has been shown to be similarly efficacious [37, 38] and national guidelines permit unsupervised treatment [39]. Alternative treatment may also reduce follow up requirements.

0% reflects un adjusted programme costs. Some argue that time preferences for delay of costs are not necessarily rational and should not be included in decision-making. 5% represents a greater time preference, argued by some to be more relevant to developing country contexts.
