目的了解武威市病毒性腹泻的病原学分布特征。方法使用描述性流行病学方法对2013年武威市病毒性腹泻监测结果进行分析。结果 6~月龄标本数最多,占总数的54.67%,轮状病毒在各月龄阳性率最高,其次为人杯状病毒、肠道腺病毒和星状病毒,经检验各病毒阳性率间差异有统计学意义(P<0.05);四种腹泻病毒阳性检出率在各年龄段之间差异均无统计学意义(P>0.05);轮状病毒和杯状病毒各月份间阳性检出率差异有统计学意义(P<0.05),轮状病毒在10-12月份阳性检出率较高,杯状病毒在2、4、6月份较高,均大于50%;杯状病毒检出率女性大于男性,差异有统计学意义(P<0.05),轮状病毒在男女间的检出率较高,分别为46.9%和41.28%。结论病毒性腹泻全年均可发生,各年龄组男女都可感染,轮状病毒阳性检出率最高,仍为该地区的主要病原,应加强病毒性腹泻的监测。
Objective To understand the etiological distribution of viral diarrhea in Wuwei City. Methods Descriptive epidemiological methods were used to analyze the results of viral diarrhea surveillance in Wuwei City in 2013. Results The number of 6-month-old specimens was the most, accounting for 54.67% of the total. Rotavirus had the highest positive rate at each age, followed by human calicivirus, enteric adenovirus and astrovirus. The positive rate of each virus was (P <0.05). The positive rates of four diarrhea viruses in all age groups were not significantly different (P> 0.05). The positive rates of rotavirus and calicivirus in each month were different (P <0.05). The positive rate of rotavirus in 10-12 months was high, and the rate of calicivirus in February, April and June was higher than 50%. The detection rate of calicivirus was higher in female than in female The difference was statistically significant (P <0.05). The detection rate of rotavirus among men and women was higher (46.9% and 41.28% respectively). Conclusions Viral diarrhea can occur throughout the year, and both men and women can be infected in all age groups. The positive detection rate of rotavirus is the highest, which is still the main pathogen in the area. Viral diarrhea should be monitored.
