This paradox can be interpreted as the evolution of a plastic strategy of feeding behavior in this field population of An. gambiae because of the greater accessibility of readily available, although less-preferred, hosts.

Both regimens were well tolerated. AMQ clears parasitemia and reduces gametocyte carriage more rapidly and causes lesser fall in hematocrit than MQ, but both regimens are effective treatment of uncomplicated P. falciparum malaria in Nigerian children.
