目的了解某部一起流行性腮腺炎暴发的流行病学调查情况。方法设计流行病学调查表,根据该部医院住院病例收集资料,统计分析相关数据。描述该次暴发的一般情况,研究发病经过,分析暴发原因,对相关指标进行频数比较以及多元线性回归分析。结果军人与非军人各发病日期分类比较差异有统计学意义,性别、年龄比较差异无统计学意义,军人患者的临床表现要重于非军人患者,两类患者接触史的比较差异有统计学意义,血清淀粉酶分级比较差异无统计学意义,患者接种疫苗的比率很低;以血清淀粉酶数据分级作为应变量,进行一次多元线性回归分析,各自变量对模型的作用差异均无统计学意义。结论这是一起由地方病例传入部队的流行性腮腺炎疫情,引起此次流行的原因之一是人群免疫水平较低;用血清淀粉酶作为临床表现轻重程度的指示指标是不合适的,而且也没有早期发现患者以阻断传播途径的流行病学意义。
Objective To understand the epidemiological investigation of mumps outbreak in some ministries. Methods The epidemiological questionnaire was designed. According to the collected data of inpatients in the Ministry of Hospital, the relevant data were statistically analyzed. Describe the general situation of the outbreak, study the pathogenesis, analyze the causes of the outbreak, compare the frequency of related indicators and multiple linear regression analysis. Results There was significant difference in the classification date of the military and non-military personnel between the two groups in terms of the difference of the sex and age, the clinical manifestation of the military patients was more than that of the non-military patients, and the difference of the contact history between the two groups was statistically significant , But there was no significant difference in serum amylase grading. The vaccination rate was very low. Serum amylase data classification was used as the dependent variable to conduct a multiple linear regression analysis. There was no significant difference in the effect of each variable on the model. Conclusions This is an epidemic of mumps imported from a local case into the army. One of the causes of this epidemic is the low level of immunity in the population. It is not appropriate to use serum amylase as an indicator of the severity of clinical manifestations, and There is also no early detection of the patient to block the epidemiological significance of the route of transmission.
