登革热的流行病学分析及防控效果研究

Epidemiological analysis and prevention of dengue fever

目的：研究登革热的流行病学分析及防控效果。方法：选择2013年1月~2014年12月在本市住院接受治疗的登革热患者834例作为研究对象。以2013年12月31日为临界点,此后实施严格的综合性防控措施。分析不同时间登革热发病情况,不同时间登革热疫情致病病毒情况,不同年龄的登革热患者发病情况。结果：在2013年~2014年期间,登革热发病时间主要位于8~11月份,2014年的登革热发病例数明显高于2013年组,差异有统计学意义（P〈0.05）;2013年及2014年,登革热疫情的致病病毒主要是DEN1型。年龄为10~69岁的登革热患者发病率最高,2013年此年龄段的发病率与2014年相比,差异无统计学意义。结论：监测登革热的流行病学资料十分必要,采取严格的综合性预防措施,对于降低登革热疫情的爆发和流行十分紧迫,值得重视。

Objective： To investigate the epidemiological patterns and prevention of dengue fever. Methods： Selected 834 dengue fever patients as the research object. Started on December 31, 2013 comprehensive prevention and control measures were applied and analyzed. Incidence of dengue in different time, different time of dengue fever epidemic pathogenic virus, den- gue fever patients in different age were analyzed. Results： From 2013 to 2014, the time of onset of dengue fever was mainly August November. The number of dengue cases of 2014 group was significantly higher than the 2013 group, the difference was statistically significant （P〈0.05）. In 2013 and 2014, dengue fever epidemic pathogenic virus was mainly type DEN1. The highest incidence of dengue fever was observed among 10-69 old patients, but the incidence in 2013 and 2014 was not significantly different. Conclusion： The epidemiological data is necessary for monitoring of dengue fever in order to take comprehen sive strict preventive measures. Reducing dengue fever outbreak and epidemic is very urgent, and is worthy of attention.
