目的研究桂林地区气象及地质因素对伤寒副伤寒发病的影响,为预防和控制伤寒副伤寒的流行提供科学依据。方法收集、汇总桂林市辖区12县1991-2005年伤寒副伤寒的发病资料及气温、降雨量等气象资料,收集伤寒副伤寒年平均发病率最高的2个县和最低的2个县共46个乡镇地质因素资料,应用SPSS10.0统计软件进行气象和地质因素对伤寒副伤寒发病的影响分析。结果桂林市伤寒副伤寒发病地区间差异有统计学意义,年平均发病率最高的县达到69.0/10万,最低的县为7.3/10万。伤寒副伤寒多年月平均发病率与多年月平均气温呈正相关,与多年月平均降雨量无统计学相关。Logistic单因素分析显示,岩溶分布中的岩溶区、岩性条件中的碳酸盐岩、碳酸盐岩夹碎屑岩、饮用水类型中的岩溶水、地下水类型中的裸露型岩溶水-裂隙溶洞水等5个地质因素与伤寒副伤寒发病相关。多因素分析显示,对伤寒副伤寒发病影响作用大小的地质因素依次是:岩溶区分布>地下水类型>岩性条件>饮用水类型。岩溶分布为岩溶区、地下水类型为碳酸盐岩裂隙溶洞水、岩性条件为碳酸盐岩、饮用水类型为岩溶水的乡镇其伤寒副伤寒发病等级显著高于其对应的其他地质因素类型。结论气温与伤寒副伤寒发病率相关;岩溶区分布是影响桂林市伤寒副伤寒发病最重要的地质因素;岩溶区、碳酸盐岩岩性地质类型、裸露型岩溶水地下水类型、岩溶饮用水类型为影响伤寒副伤寒发病的地质因素。
Objective To study the impact of meteorological and geological factors in Guilin on the incidence of typhoid and paratyphoid fever, and to provide a scientific basis for the prevention and control of the epidemic of typhoid and paratyphoid fever. Methods A total of 46 counties with the highest average annual incidence rate of typhoid fever and paratyphoid fever and the lowest 2 counties were collected and summarized from January 1991 to December 2005 in the county of Guilin. Analysis of the influence of meteorological and geological factors on the incidence of typhoid and paratyphoid fever using SPSS10.0 statistical software. Results There were significant differences in the incidence of typhoid and paratyphoid fever in Guilin. The counties with the highest annual average incidence reached 69.0 / lakh and the lowest county was 7.3 / lakh. The monthly average incidence of typhoid and paratyphoid fever has a positive correlation with the monthly mean temperature over many years and has no statistical significance with the monthly average rainfall over the years. Logistic univariate analysis showed that karst areas in karst distribution, carbonate rocks in lithological conditions, carbonate clastic rocks, karst water in drinking water types, bare karst water-fissures in groundwater types Five geologic factors, such as cave water, are related to the incidence of typhoid and paratyphoid fever. Multivariate analysis showed that the geological factors influencing the incidence of typhoid and paratyphoid fever were as follows: karst area distribution> groundwater type> lithology condition> drinking water type. The distribution of karst is karst area, groundwater type is carbonate rock fissure cave water, lithology condition is carbonate rock and township drinking water type is karst water, its typhoid and paratuberculosis incidence is significantly higher than other corresponding geological types . Conclusions The temperature is related to the morbidity of typhoid and paratyphoid fever. The distribution of karst area is the most important geological factor affecting the incidence of typhoid and paratyphoid fever in Guilin. The karst area, carbonate rock lithology, bare groundwater type, karst drinking water type As a geological factor affecting the incidence of typhoid and paratyphoid fever.
