The infestation rate of total 2,515 children was 38.6% in average (21.2 % in boys and 57.5% in girls) . The reduction rate of head louse infestation was 93.4% with a single treatment and 94.8% with double consecutive treatments with about 10 days interval, which indicated that a single treatment would be recommended for the mass treatment in the community.
