目的评估建瓯市2014年登革热暴发事件防控工作的阶段性效果,研判疫情趋势。方法在现场流行病学调查、相关政策、文献扫描的基础上,采用专家会商法进行风险评估。结果 2014年9月18日,建瓯发现登革热疫情事件,疫情分布于东峰和吉阳镇。背景识别资料为截至10月8日24:00,东峰镇登革热罹患率为97.46‰,吉阳镇罹患率为0.22‰;两地疫情无流行病学关联。两地蚊媒密度本底布雷图指数分别为53.64和46.00,均为新发疫区,人群普遍易感。于9月19日起采取卫生应急措施,疫情于9月27日、10月2日两个时间点迅速下降,无重症死亡报告,无新疫点,截至10月6日两地布雷图指数分别为0.96和7.40。结论基于上述背景评估认为,前期防控见效,但存在防蚊灭蚊死角、专业队伍配备不合理、部分留观病例管理不到位、实验室检测能力建设缺位等风险点,疫情仍可能散在拖尾或反弹;远期不排除有更多点暴发的可能。
Objective To evaluate the stage effect of prevention and control of dengue outbreak in 2014 in Jianou city and to determine the epidemic trend. Methods On the basis of field epidemiological investigation, relevant policies and literature scans, experts were used to carry out risk assessment. Results On September 18, 2014, an outbreak of Dengue Fever was found in Jianou. The outbreaks were distributed in Dongfeng and Jianyang Towns. Background identification data as of October 8 at 24:00, Dongfeng Dengue fever attack rate was 97.46 ‰, Ji Yang town attack rate was 0.22 ‰; epidemic situation between the two places without epidemiological association. The mosquito density background of the two places were respectively 53.64 and 46.00, which were all newly emerging areas, and the population was generally susceptible. Health emergency measures were taken on September 19, the epidemic rapidly dropped at two time points on September 27 and October 2, and no serious deaths were reported. There was no new outbreak. As of October 6, the Bretton Islands 0.96 and 7.40. Conclusion Based on the above background assessment, it is considered that the early prevention and control are effective, but there are still some dead spots such as mosquito and mosquito elimination, irrational allocation of professional teams, inadequate management of some cases for observation, absence of laboratory testing capacity, Tail or bounce; forward does not rule out the possibility of more point outbreaks.
