目的了解流行性出血热疫情调查和处理过程,为今后调查和处理类似疫情提供参考。方法流行性出血热疫情发生时,在疫村、病家开展流行病学调查;在疫村发动群众开展环境卫生整治及灭鼠、灭蚤工作:在灭鼠前后进行鼠密度调查;灭鼠7 d后灭蚤,并在喷洒灭蚤前后对鼠体染蚤指数进行观察。将捕获鼠送鼠疫强毒室检鼠检蚤;对结果进行鼠密度计算及统计学检验。结果疫村按上述方法处理疫区后未出现二代病例。疫村灭鼠前鼠密度5.7%高于灭鼠后鼠密度3.5%,差异有统计学意义(χ~2=23.1,P<0.05);喷洒灭蚤前活鼠体表染蚤指数(1.5)高于喷洒灭蚤后活鼠体表染蚤指数(1.0),差异有统计学意义(χ~2=62,P<0.05)。结论蒙自市疫村发生流行性出血热疫情与该村环境卫生差、鼠密度高有关。
Objective To understand the investigation and treatment of epidemic of epidemic hemorrhagic fever and provide reference for future investigation and treatment of similar epidemic. Methods Epidemic investigation was carried out in the affected villages and sick families when epidemic situation of epidemic haemorrhagic fever occurred. The masses in the affected villages were mobilized to carry out environmental sanitation treatment and rodent control work to eliminate fleas and fleas. Rat densities were investigated before and after anti-rodent control. d after the fleas, and fleas flea index was observed before and after spraying fleas fleas. Will capture the rats sent to the plague strong ventricular septicemia; the results of rat density calculations and statistical tests. Results The second generation of cases did not appear in the affected villages after the affected villages were treated as above. The density of pre-extermination rats was 5.7% higher than that of rats ex-rats (3.5%), the difference was statistically significant (χ ~ 2 = 23.1, P < Which was higher than that of the flea index (1.0) in live mice after spraying fleas, the difference was statistically significant (χ ~ 2 = 62, P <0.05). Conclusion Epidemics of epidemic hemorrhagic fever in the epidemic area of Mengzi City are related to poor environmental hygiene and high density of mice in this village.
