本次调查中小学生共1403人,检出沙眼患者276人,患病率为19.64％,其中中学患病率为23.61％,小学患病率为14.81％,二者有非常显著性差异(P<0.01)。中学患病率高于小学可能与前者接触社会范围广泛,感染机会相对较多有关。沙眼患病率无明显随年龄增长而上升或下降的趋势,但13岁以上各年龄组患病率较13岁以下各年龄组为高。
In this survey, a total of 1403 primary and secondary school students, 276 were detected trachoma patients, the prevalence was 19.64%, of which the prevalence was 23.61% in secondary schools, primary school prevalence was 14.81%, both very significant differences (P < 0.01). The prevalence of secondary school is higher than that of primary school may be related to the former social contact with a wide range of relatively more opportunities for infection. The prevalence of trachoma showed no obvious increase or decrease with age, but the prevalence of each age group over 13 years old was higher than that of all age groups under 13 years old.
