Epidemiology of hemorrhagic fever with renal syndrome in Changping district in Beijing, 1998 - 2009

Objective To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Changping from 1998 to 2009, and provide scientific evidence for the prevention and control of the disease. Methods Descriptive epidemiological analysis was conducted on the incidence data of HFRS in Changping from 1998 to 2009. Results A total of 132 HFRS cases were reported during this period, and no death was reported. The incidence of HFRS was 1.63/lakh. The cases were mainly distributed in rurbania, and most cases were young adults. The male to female ratio of the cases was 3.40 ∶ 1. Migrant workers and farmers were the mostly affected populations. The incidence peak of the disease was during winter-spring. Rodent surveillance indicated that the predominant host animal was Rattus norvegicus and the antigen positive rate among rats was 1.64%. Conclusion The incidence of HFRS declined steadily in Changping, which might be attributed to the comprehensive prevention and control activities, such as vaccination and deratization, and the improvement of environment in recent years.
