[Study on geographical distribution of leptospirosis in China].
Since 1955, Leptospirosis has been recognized as a notifiable infectious disease in China. According to the data gathered from 26 provinces of China (except for Taiwan) in 1955-1993, the average morbidity and mortality were 7.08/10(5) and 1.02% respectively. Distribution of the disease involved 26 provinces in China (not including Taiwan). The trend of the disease has been steady for recent years but outbreaks occasionally occurred, especially in several southern provinces of China. Potential risk factors may exist in these areas. Distribution of endemic areas of this disease is located between 25 degrees-35 degrees latitude and 100 degrees-120 degrees longitude i, e. those provinces along with drainage areas of the Yangtze River and the Huaihe River.
