In the paper by Chantal M Morel and colleagues (BMJ 2005;331:1299-302) an error in the cost calculations for malaria treatment in two African regions resulted in an underestimate of the costs of treatment interventions. Correct values for the health maximising set of interventions are given in the revised table 6.

Revised table 6 Costs, effectiveness, and cost effectiveness of the health maximising set of interventions in the two regions Afr-D and Afr-E

Region and intervention	Average yearly costs ($int)	Average yearly effectiveness (DALYs averted)	Average cost effectiveness ($int/DALY averted)	Incremental cost effectiveness ($int/DALY averted)

Insecticide treated bed nets plus indoor residual spraying plus case management with artemisinin based combination therapy plus intermittent presumptive treatment in pregnancy (95% coverage)	434,229,098	14,561,792	36	48
