Malaria: Efficacy of monotherapies in Cameroon
...mixture. The molecular approach, adapted to the varied epidemiological backgrounds that prevail in Cameroon, is therefore highly promising as a tool for tracking the evolution of resistance to monotherapies and thus for helping to improve malaria control strategies.
