| Abstract: |
| 浙江省天台县1983年12月和1984年1月,3月,冬春两季在全县流行性出血热10个重点发病乡,应用0.5%磷化锌红薯块和大米毒饵,开展了室内和野外大面积灭鼠,共投放红薯块毒饵44,997斤;大米毒饵24,438斤。共拾鼠尸177,312只。野外鼠密度从29.81%下降到2.47%;室内从12.73%下降到4.92%。1984年1~6月份流行性出血热发病比去年同期下降38%。肯定了0.5%磷化锌毒饵在流行性出血热重点疫区大面积灭鼠的价值。为老药新用提供了经验。 |

| In the Tian-tai County of Zhejiang Province, Epidemic hemorrhagic fever occurred in 10 focal points in two seasons Covering the winter of 1983 and the Spring of 1984, from Dec. of 1983 to Jan.& mar. of 1984. For mass deratization in a large area in houses as well as in the field, popular poison bait with small pieces of sweet potato & rice grains containing 0.5% zinc phosphide was adninistered to the places in need. As a result, a large number of rats were killed, with murine corpora amounting 177,312. The rat density in the field declined from 29.81% to 2.47%, whereas that in doors dropped from 12.73%to 4.92%. The morbidity rate of epidemic hemorrhagic fever in jan-june 1984 was found to drop 38% as compared with that in the same period in the previous year. Thus it permits us to conclude that 0.5%zinc phosphide in toxic bait is useful in deratization in the control of epidemic hemorrhagic fever. The present experiment in the focal points of epidemic area provides some experiences for new application of an old medicament. |
