农村粪便无害化处理试点区，小学生甲型肝炎、伤寒、副伤寒３项抗体阳性率分别为６２．９７％、４８．７３％和４７．６１％；条件基本相同的非试点农村，小学生此３项抗体水平分别为７０．９５％、５５．５４％和５４．６３％，比试点区分别高出７．８９、６．８１和７．０２个百分点，在一定程度上反映出粪便无害化处理所起到的防病效果，其远期效果可能更为显著。 The positive rates of hepatitis B virus, typhoid fever and paratyphoid fever in primary and secondary school students were 62.97%, 48.73% and 47.61% respectively in the pilot area for innocuous treatment of rural excrement. In non-experimental rural and primary school students with basically the same conditions The three antibody levels were 70.95%, 55.54% and 54.63%, respectively, which were 7.89, 6.81 and 7.02% higher than the experimental areas, respectively, to a certain extent, The anti-disease effect of the treatment can play a more significant role in the long-term effect.
