Comparison of treatment schedules for Plasmodium vivax infections in the Solomon Islands.

A total of 26 patients infected with Solomon Islands strains of Plasmodium vivax was treated with one of three regimens of cloroquine-primaquine, in an attempt to determine the relapse patterns and the response to treatment of the local strains of parasite. The results suggest that the standard course of chloroquine-primaquine provides a radical cure for the strains of Plasmodium vivax from the Solomon Islands, provided that strict supervision of drug administration is enforced.
