宁德市恙虫病地理流行病学调查

目的 对宁德市的恙虫病进行地理流行病学调查，为今后防制提供依据。方法 捕获农田活鼠捡恙螨，分析宿主动物及媒介昆虫的种群分布，并用PCR技术检测病原体，采集人和鼠血清检测恙虫病抗体。结果发现宁德市恙虫病的宿主动物有17种之多。恙螨有2科10属29种，存在以地里纤恙螨为主要传播媒介夏秋季流行和小板纤恙螨为主要传播媒介冬春季流行的自然疫源地。结论基本查明宁德市恙虫病的主要宿主动物和媒介恙螨的种群、数量、地理分布、人群分布及流行规律.

Geographical Epidemiology of Tsutsugamushi in Ningde City

Objective In order to provide useful information for prevention and control of tsutsugamushi to study its geographical epidemiology.Methods First, the live mice in field were captured to test chigger mites. Second, the species distribution of the animal hosts and the insect vectors were analysed. Third, the PCR technology was used to detect the pathogen, and then the blood serum of mice and human being was collected to monitor the antibody to tsutsugamushi. Results The investigation indicated that there were 17 species of animal hosts in our region where the chigger mites could be divided into 2 families,10 genus,29 species. There were some places where the two kinds of tsutsugamushi epidemics, one of which was caused mainly by L.deliense outbreaking often in summer and autumn, the other was caused mainly by L.scutellare outbreaking often in winter and spring, both belonged to the infection type of natural focus. Conclusion We found out the primary animal host of the parasites, and much important information on the chigger mite vector and the main host animals of tsutsugamushi with species, quantities, geographical distributions, population distributions and the laws of the epidemic.
