目的分析广州市2010-2012年登革热病例诊断报告情况,探讨登革热病人发病后到疫情报告的影响因素,为进一步加强疾病监测,避免登革热疫情扩散蔓延提供参考。方法对广州市2O10-2012年网络直报病例、部分现场调查病例的发病后就诊、诊断、报告等时间间隔特点进行分析,探讨登革热病人从发病至报告中各环节时间问隔的影响因素。结果 311例网络直报病例中,发病至诊断的时间为发病至报告的主要时间段(中位数7 d),原始报告为确诊病例(临床诊断病例及实验室诊断病例)的发病至诊断时间较原始报告为疑似病例的发病至诊断时间长(中位数相差1 d),其差异有统计学意义(P<0.05)。259例现场调查病例中,影响登革热病例从发病至报告的时间最主要的是发病至诊断的时间(中位数8 d)。结论广州市登革热疫情报告及时性的主要影响因素为病例诊断的及时性,各相关单位应提高及早发现病例、及早报告,及早处理的能力。
Objective To analyze the diagnosis of dengue cases in Guangzhou from 2010 to 2012, and to explore the influencing factors of dengue fever after the onset of the epidemic so as to provide reference for further strengthening disease surveillance and avoiding the spread of dengue fever. Methods To analyze the characteristics of post-morbidity, diagnosis, reporting and other intervals between 2005 and 2005 in Guangzhou city, and to explore the influencing factors of dengue fever patients’ time interval from onset to reporting. Results Among the 311 cases of direct online reporting, the time from onset to diagnosis was the main time period from onset to report (median 7 days). The original report was from the onset of diagnosis (clinical diagnosis and laboratory diagnosis) to diagnosis The difference was statistically significant (P <0.05) as compared with the original report of suspected cases of onset to diagnosis of a long time (median difference of 1 d). Among the 259 field survey cases, the most important factor affecting the time from onset to reporting of dengue cases was the time from onset to diagnosis (median 8 days). Conclusions The main influencing factors of timely reporting of dengue fever in Guangzhou are the timely diagnosis of cases. Relevant units should improve their early detection of cases, early reporting and early treatment.
