为了解婴幼儿感染性腹泻流行规律,为今后的防治工作提供科学依据,进行统计分析感染性腹泻疫情资料,采用核实诊断,初步调查,病原学及血清学检测等流行病学调查方法。得出结果,共发病110例,发病率为11.84/10万,均为18个月龄以内婴幼儿,7～12个月龄儿发病率占61.82％(68/110)。男女之比为3.4:1(85/25),1997年12月下旬～1998年1月上旬为流行高峰。用酶联免疫吸附法(ELISA)检测35份大便标本,轮状病毒抗原阳性1份。结论,此次婴幼儿腹泻流行为一起以肠道病毒(人类轮状病毒HRV)感染为主的感染性腹泻。提倡母乳喂养,利用多种途径提高婴幼儿肠道免疫水平。
In order to understand the epidemic law of infectious diarrhea in infants and young children, provide a scientific basis for future prevention and treatment work, conduct statistical analysis of epidemic data of infectious diarrhea, adopt epidemiological investigation methods such as verification diagnosis, preliminary investigation, etiology and serological detection. The results showed that a total of 110 cases were found, the incidence rate was 11.84 / 100000, all of which were infants and young children within 18 months old. The incidence rate of children aged 7-12 months was 61.82% (68/110). The ratio of men to women was 3.4: 1 (85/25), with a peak in late December 1997 to early January 1998. 35 stool samples were detected by enzyme-linked immunosorbent assay (ELISA), and 1 rotavirus antigen was positive. In conclusion, the prevalence of diarrhea in infants and young children was mainly associated with infectious diarrhea with enterovirus (human rotavirus HRV) infection. Promote breastfeeding, use a variety of ways to improve intestinal immunity in infants and young children.
