近十几年来,流行性出血热(简称出血热)的疫情在我国不少地区有所扩大,并在某些水利工地和农村发生了爆发流行。为了研究该病的流行规律,探索和掌握疫情预测的方法,我们从1966～1971年,对发生出血热较多的城西湖、丹阳湖等农场,进行了较全面的流行病学调查,分析了造成该病流行的各种因素,初步总结出疫情预测的方法。1972年以来,通过近9年的实践,证明本法 In the past decade or so, the outbreak of epidemic hemorrhagic fever (referred to as haemorrhagic fever) has expanded in many areas of our country and outbreaks have occurred in some water conservancy sites and rural areas. In order to study the epidemic law of the disease and to explore and master the methods of epidemic situation prediction, we conducted a comprehensive epidemiological investigation from 1966 to 1971 on farms with such large amounts of hemorrhagic fever as Chengxi Lake and Danyang Lake. The various factors that caused the epidemic, initially summed up the method of epidemic prediction. Since 1972, this law has been proved through nearly nine years of practice
