【Abstract】 Objective To evaluate the preventive effect of naphthoquine against vivax malaria and chloroquine-resistance falciparum malaria. Methods The study was carried out in villages with 5% over of carrying malaria plasmodium rate in Jinghong and Mengla Counties, where are epidemic vivax and chloroquine-resistance falciparum malaria and located China-Mynamar and China-Laos border areas. 1 547 persons enrolled into the study and were divided three groups: Group A, adults were given 4 tablets (400 mg) naphthoquine in single time per month, two consecutive months; Group B, adults were given 4 tablets (400 mg) naphthoquine in single time, only one month; Group C taken placebo as control.
