目的 为控制云南省旋毛虫病的暴发提供可行性的干预措施。 方法 1997～ 2 0 0 0年 ,在两现场实施人群干预措施 (群体健康教育、不良饮食行为的监督、培训乡村医生 )及传染源干预措施 (加强生猪屠宰检疫及市场肉类检疫、开展猪旋毛虫病的防治、大力提倡灭鼠 )。 结果 两研究现场 3年多未发生过旋毛虫病的暴发 ,人群个人行为及对旋毛虫病的认识发生了明显的改变 ,食生肉者从干预前的 72 .74 %降至 4 7.4 3% (P<0 .0 1) ,具备旋毛虫病常识者从干预前的15 .4 7%增至 73.6 2 % (P<0 .0 1)。干预前后旋毛虫血清抗体阳性率 :人群分别为 1.91%、1.0 7% (P>0 .0 5 ) ,猪分别为8.6 6 %、0 (P<0 .0 1)。生猪检疫 1340 9头 ,未检出旋毛虫病猪。 结论 在旋毛虫病疫区实施人群及传染源的干预措施 ,可以有效地控制旋毛虫病的暴发
Objective To provide feasible interventions for controlling the outbreak of Trichinosis in Yunnan Province. Methods From 1997 to 2000, population interventions (group health education, supervision of poor dietary behaviors, training of rural doctors) and interventions of source of infection (strengthening of pig slaughtering and quarantine and market meat quarantine, swine hair removal Prevention and treatment of insect diseases, vigorously promote deratization). Results No outbreaks of Trichinosis were found in the study sites for more than three years. The behavior of the individuals and their cognition of Trichinosis were significantly changed. The number of raw meat workers decreased from 72.74% before intervention to 7.43% P <0.01), those with common knowledge of trichinosis increased from 15.47% before intervention to 73.6% (P <0.01). Serum antibody positive rate of Trichinella spiralis before and after intervention were 1.91% and 1.07% respectively (P> 0.05), and pigs were 8.66% and 0 (P <0.01) respectively. Pig quarantine 1,340 9, did not detect trichinella pig. Conclusions Interventions on crowd and source of infection in the region of Trichinella were effective in controlling the outbreak of Trichinellosis
