摘要
目的:了解诺如病毒发生发展的流行病学特征和影响因素,为诺如病毒的防控提供数据支持。方法:根据纳入标准筛选感染性腹泻患者进行样本采集,应用实时荧光定量(RT-PCR)反转录聚合酶链反应检测诺如病毒核酸。结果:2017年—2020年共送检样本711例,其中阳性118例。不同年份发病率比较,差异无统计学意义(P>0.05);不同季节的阳性率和不同年龄组比较,差异有统计学意义(P<0.05)。男性阳性率明显高于女性,差异有统计学意义(P<0.05)。结论:铜仁市诺如病毒发病年龄呈低龄化,男性发病率高于女性,秋冬季节为高发期,应结合诺如病毒流行特征采取相应的防控措施。
Objective:In order to understand the epidemic characteristics and influencing factors of the occurrence and development of norovirus,and provide data support for the prevention and control of norovirus.Methods:According to the inclusion criteria,patients with infectious diarrhea were screened for sample collection,and real-time fluorescence quantitative(RT-PCR)reverse transcription polymerase chain reaction was used to detect Norovirus nucleic acid.Results:From 2017 to 2020,there were 711 samples.Among them,118 cases were positive.There was no significant difference in incidence rate in different years(P>0.05).The positive rate in different seasons compared with different age groups,the difference was statistically significant(P<0.05).The positive rate of males was significantly higher than that of females,and the difference was statistically significant(P<0.05).Conclusion:The incidence of norovirus in Tongren is younger,and the incidence rate of male is higher than that of female.Therefore,corresponding prevention and control measures should be taken according to the epidemic characteristics of norovirus in Tongren.
