Application of astra method to evaluate the status of active trachoma in the primary school children

To identify communities with high rate of active trachoma for prioritizing interventions, the sampling method of ASTRA (Acceptance Sampling Trachoma) was applied in this study in order to find the active trachoma rate among pupils at primary schools in Binh Xu yen district, Vinh Phuc province. The results showed that 3 out of 13 communes had high rates of active trachoma among primary school children. The mean rate of active trachoma among these pupils was 8.2% (95%CI: 6.5%. 9.9%). Some risk factors of active trachoma among these subjects include unsafe water for face washing, sharing face cloth, children with dirty face, unsanitary latrines, high density of home flies, and low family income.
