Abstract:
Objective To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Shijiazhuang City,and to provide scientific evidence for finding available prevention and control measures against the disease.Methods Using data retrospective method,the monitoring data of HFRS in Shijiazhuang from 1984 to 2015 were collected and divided into 1984-1993,1994-2003 and 2004-2015 periods.The incidence changes of HFRS in time,district and population in different periods were analyzed,and the time distribution of HFRS cases was analyzed on a seasonal basis.Results A cumulative total of 12 692 cases (accounting for 4.94/100 000) of HFRS,including 56 deaths,were reported in Shijiazhuang from 1984 to 2015.The particular years with the two peeks of HFRS epidemic were 1986 and 1999,the incidences of HFRS were 16.14/100 000 and 14.25/100 000,respectively.The incidence of HFRS maintained at a high level from 1998 to 2002,the average annual incidence was 12.21/100 000.And then,the incidence of HFRS declined quickly.The incidence of HFRS in Shijiazhuang kept at a lower level in 2011-2015,the average annual incidence was 0.26/100 000.42.91％ (5 446/12 692) of cases mainly occurred in spring;90.44％ (11 479/12 692) of cases were concentrated in 11 counties (cities,districts) of the eastern part of Shijiazhuang.Most cases were young males,the ratio of males to females was 2.43:1.00 (8 997/3 695),and 93.20％ (1 1 829/12 692) of them were adults.The majority of the cases were framers,accounting for 70.91％ (9 000/12 692),and the second large group was workers,accounting for 11.13％(1 413/12 692).Conclusions Overall,the incidence rate of HFRS has reduced continuously and maintained at a low level in recent years;epidemic areas are widely distributed,but in uneven distribution,and presented with obvious regional characteristics;these cases have mainly occurred in spring.The specific measures for control and prevention of HFRS should be taken according to the epidemic characters in different areas.
