湖北省自 1960年报告钩端螺旋体病 (简称钩体病 )以来 ,至 2 0 0 0年已累计发病 15万余例 ,病死 2 0 0 0余例。该病地理分布广泛 ,动物宿主多 ,菌型复杂。为了掌握钩体病流行规律 ,控制该病流行 ,我们对影响钩体病发生、流行的若干因素作了调查 ,拟通过对其流行因素的主动监测 Since 1960, leptospirosis (referred to as leptospirosis) has been reported in Hubei Province. By the year 2000, more than 150,000 cases have been reported and more than 20,000 have died. The disease is widely distributed geographically, animal hosts and complex bacteria. In order to grasp the prevalence of leptospirosis and control the prevalence of leptospirosis, we investigated several factors affecting the occurrence and prevalence of leptospirosis and proposed that we should actively monitor the prevalence of leptospirosis
