【摘要】 报告本省钩体病在各地理区划中发病率差别较大，同海拔高度无关，而与降雨量密切相关。每年6─11月为发病高峰；患者多系青壮年，皆因接触疫水而罹患。有哨齿类1科2属9种，黄毛鼠为优质种，带菌率26．6％，是主要传染源。病人分离菌株与鼠类携带菌群相符。发现90年代健康人感染菌群与70年代有所不同，且感染率甚高。对流行形式、疫源地类型、水体污染等流行病学意义作了论证。更多还原

【Abstract】 This paper reports that the incidences of leptospirosis were very different in various geographical divisions and it was not related to the height above sea level but closely connectied with rainfall. The incidence peak occurred from June to Novermber every year ; Most patients were youngsters and adults who were all infected by contacting with the water in which leptospirae existed. The infectious sources consisted of one family, two genera, nine species; the Rattus losea was the superior species, whose bacteria -carrying rate was 26. 6%and therefore such an animal was the main infectious source of this disease.The bacteria isolated from the patients conformed to those carried by rats. It was found that the bacteria species infecting healthy people in 1990s were different from those in 1970s, moreover, the infection rate was more higher in 1990s than in 1970s, The epidemiological meanings of epidemicmode, types of epidemic areas,polluted water and so on were also demonstrated.更多还原
