2010-2016年四川省重点水域血吸虫病哨鼠监测报告

Surveillance Report of Schistosomiasis Sentinel Mice in Key Waters in Sichuan Province From 2010 to 2016

目的为发现四川省血吸虫感染的高危风险环境,减少疫水接触,预防血吸虫感染。方法在重点流行地区设立哨鼠监测点,小白鼠在水体中8小时,饲养35天,解剖观察血吸虫感染情况。结果 2010-2016年四川省的17个血吸虫病流行县设立73个监测点,投放哨鼠3 114只,回收哨鼠3 037只,总回收率为97.53%;饲养期间死亡73只,死亡率为8.48%,共解剖2 964只。仅2010年在西昌解剖发现一条单性血吸虫雄虫,哨鼠感染率0.03%,其余年度未发现阳性哨鼠。结论 2010-2016年四川省血吸虫病哨鼠监测结果和全省防治工作情况、达标进程相一致,今后应探索更敏感和及时的疫水监测方法。

Objective To identify high-risk environments for schistosomiasis infection in Sichuan Province, and to reduce water contact to prevent schistosomiasis infection. Methods In the key areas, sentinel control points were established, and mice were placed in water for 8 hours and bred for 35 days and then dissected to observe the condition of schistosomiasis infection. Results From 2010 to 2016, 73 surveillance sites were set in 17 prevalent counties in Sichuan Province, and 3 114 mice were sent to the sentinel sites. A total of 3 037 mice were recovered （the recovery rate was 97.53% ）. Seventy three died during the breeding period and the death rate was 8.48%. A total of 2 964 were dissected. Only in 2010 a male schistosome was found in Xichang, the sentinel mouse infection rate was 0. 03% ; no positive sentinel mouse was found in the other years. Conclusion From 2010 to 2016, the schistosomiasis sentinel surveillance results in Sichuan province agreed with the prevention and control work and target achievement in the province. More sensitive and timely surveillance methods of epidemic water should be explored in the future.
