Abstract:
Objective:To analyze the changes of the characteristics of Hemorrhagic fever with renal syndrome (HFRS) in Jingzhou City in different periods.
Methods:According to the HFRS epidemic data of Jingzhou City in 2009-2018, based on the incidence rate, the HFRS epidemic situation in Jingzhou City was divided into three periods: 2009-2012 (low), 2013-2016 (middle), and 2017-2018 (high). Descriptive epidemiological methods, standard deviation ellipse and spatio-temporal scanning analysis were used to analyze the time, region, population distribution and temporal and spatial trends of HFRS epidemic in the three periods.
Results:The incidence of HFRS in Jingzhou City in the three periods was seasonal and bimodal. The peak incidence included spring and summer peaks (May-July) and autumn-winter peaks (January, November-December). The HFRS cases in Jingzhou City were concentrated in Jianli County, Jiangling County and Honghu City in the three periods. The incidence rates were 0.48/100 000, 1.98/100 000, 0.84/100 000, 0.89/100 000, 1.88/100 000, 1.20/100 000; 4.82/100 000, 13.37/100 000, and 4.58/100 000. The incidence of HFRS in males was higher than that in females in the three periods (χ2=43.38, P < 0.05); the occupations of HFRS in the three periods were mainly farmers, which were 56.26%(69/122), 69.61% (126/181), 74.94% (293/391), respectively. In 116 farmers, growing rice [48.28% (56/116)] and shrimp rice [27.59% (32/116)] were mostly. From the age point of view, the incidence rate in 2009-2017 was 55 to 64 years old; the incidence rate of 2018 was 60 to 69 years old. The results of standard deviation ellipse analysis showed that the expansion trend of HFRS epidemic areas in Jingzhou City was not obvious, and the center of gravity was located in Jianli County or Jiangling County. Spatio-temporal scans revealed that the first-class spatial-temporal clustering areas in the three periods were 2 towns and villages in Jiangling County, and the gathering time was from December 7, 2010 to January 2, 2011; in some townships in Jiangling County and Shacheng District, the gathering time was from December 7, 2016 to February 28, 2017; some townships in Jiangling County and surrounding counties, gathered from April 27, 2018 to July 16, 2018.
Conclusions:The HFRS epidemic season in Jingzhou City in different periods is basically the same; the high-incidence areas are basically the same, but there are local fluctuations; the population is mainly male farmers, and the age of high-incidence has shifted back. We should adapt to local conditions and formulate scientific and reasonable comprehensive prevention and control measures.
