目的探讨日照市2011-2014年恙虫病流行特征和变化趋势,为有效预防和控制恙虫病的发生提供依据。方法采用描述性流行病学、集中度法(M)、圆形分布法(raleighstest检验)对日照市2011-2014年恙虫病疫情资料进行分析,分析恙虫病的发病率、发病时间、人群、空间分布。率的比较用χ2检验。结果 2011-2014年日照市累计报告恙虫病病例397例,年均发病率为3.49/10万,发病呈逐年上升趋势(χ2=68.97,P<0.001)。日照市恙虫病有明显的季节分布,发病高峰为每年的10月上旬至11月中旬。各区县东港区发病率最高。40~80岁的农民发病占大多数,女性(8.05/10万)发病率高于男性(5.91/10万),差异有统计学意义(χ2=9.37,P<0.01)。结论日照市恙虫病发病高峰为10月上旬至11月中旬,农村是恙虫病的重点防控地区,中老年农民是恙虫病的高发人群,防制重点应是秋冬季的农村地区。
Objective To investigate the epidemiological characteristics and trend of tsutsugamushi disease in Rizhao from 2011 to 2014 and provide evidence for the effective prevention and control of tsutsugamushi disease. Methods Descriptive epidemiology, concentration method (M) and circular distribution (raleighstest test) were used to analyze the epidemic data of Rhesus tsutsugamushi from 2011 to 2014 in Rizhao City. The incidence, onset time, population, space distributed. Rate comparison using χ2 test. Results A total of 397 tsutsugamushi cases were reported in Rizhao City from 2011 to 2014, with an average annual incidence of 3.49 / 100 000. The incidence was gradually increasing (χ2 = 68.97, P <0.001). Rizhao tsutsugamushi disease has a clear seasonal distribution, the peak incidence of early October to mid-November each year. Donggang District, the highest incidence. The incidence of peasants in 40 ~ 80 years old was the majority, while the incidence rate of female (8.05 / 100000) was higher than that of males (5.91 / 100000). The difference was statistically significant (χ2 = 9.37, P <0.01). Conclusion The peak incidence of scrub typhus in Rizhao City is from early October to mid-November. Rural areas are the key areas for prevention and control of scrub typhus. Middle-aged and elderly peasants are high-risk groups for scrub typhus, and the prevention and control should focus on rural areas in autumn and winter.
