摘要
我国脊髓灰质炎发病数继１９９３年降至历史最低水平后，１９９４年又下降了５３％，且病例呈高度散发，爆发明显减少。１９９４年有病例报告的县数为２２５个，其中有病例爆发的县２个，爆发病例占总病例的４．２％。野病毒分布范围明显缩小，由野毒引起的病例数减少为６例。但脊髓灰质炎流行的地区差异依然存在：由广东、海南、福建组成的原东南沿海高发区，１９９４年病例数大幅度下降，病例在全国所占比例明显降低；与此相反，由广西、云南、贵州、四川四省组成的西南高发区，病例数呈明显上升趋势，其１９９４年病例数约占全国的一半。在未来的一两年中，应将１９９４年发现野毒株的新疆、福建、湖北三省及西南高发区四省列为我们开展消灭脊髓灰质炎工作的重点省份。通过继续加强常规免疫工作及开展新一轮的全国强化免疫日活动，进一步提高我国儿童尤其是流动人口中儿童及计划外生育儿童的免疫水平，以求在最短时间内、以最小的代价消灭脊髓灰质炎野病毒。
n 1994,the number of reported polio cases was
307 in China. This number was 53%lower than that in 1993, and was the
lowest record ever in China. In1994,the distribution of polio cases
was highly dispersed and the number of outbreak was reduced
obviously.Of 225 counties which reported polio cases in 1994,polio
outbreak occured in 2 counties. Cases due to polio outbreak
ac-counted for 4.2%of the total cases. The distribution of polio wild
virus was narrow but the regional difference still existed.In the
southeast,high risk region for polio consisting
Guangdong,Hainan,Fujian three provinces,the number of polio cases
decreased remarkably in 1994. On the contrary,in the southwest region
which,consisting Guangxi,Yunnan,Guizhou,Sichuan four provinces,the
number of polio cases increased obviously,accounted for approximately
a half of the total number in 1994.During the coming 1 to 2 years,we
should emphasis on these regions and provinces where high incidence
was noticed in our polio eradication program. Those provinces should
include Xinjiang,Fujian,Hubei three provinces that polio wild virus
was identified in 1994,and Guangxi,Sichuan,Guizhou,Yunnan in the
south west region as well. We should further increase Polio
vaccination coverage of children especially floating and unplanned
ones through strengthening routine immunization and carring out new
national immunization day activity.
