Abstract:

Objective  To analyze the endemic characteristics and development trend of the epidemic hemorrhagic fever(EHF) in Jilin province for evidences to plan appropriate control and prevention measures for this entity. Methods  The epidemic data on EHF in Jilin province from 2005 to 2014 was retrieved from the reporting system of national CDC and statistically analyzed. Results  Incidence of EHF in Jilin province was peaked in 2005 and declined to the lowest in 2011. The peak incidence was seen in between April and June as well as from November to following January. EHF was prevalent nearly in each city and autonomous prefecture in a 10 year period. The top three hit areas included Yanbian Korean Autonomous Prefecture, Baishan city and Jilin city in 2005, and Baicheng, Tonghua and Liaoyuan in 2014. Although EHF was reported in all age groups, yet males were more affected than females. The incidence was primarily between 30 and 59 years of age, and farmers accounted for the major population. Conclusion  The incidence of EHF in Jin Jilin province appears to increase in the past few years in general, and older population seems more affected. Geographical trend for the disease includes a notable shift from rural to urban areas and from east areas to the west. These findings suggest that relevant administrations should strengthen the surveillance over the population living in the highest endemic areas and in those areas with increasing morbidity, as well as plan health education and environment control before the seasonal prevalence of EHF.
