| Abstract: |
| 在我省南亚热带双季稻种植区总人口78,698人的孟连县进行钩体病调查,一年内检诊患者1,752例,实验室确诊钩体病125例,年发病率158.83/10万,远远超过历史和同类地区的记录。在当地传染病中居第3位。但发病率因地、时性别、年龄而异,坝区高达526.9/10万,半山区97.7/10万,山区60.3/10万;2~12月均可见病例发生,但8月最高(36.0/10万);男性(214.52/10万)显著高于女性(102.36/10万);各年龄组中20~24岁组最高,达435.0/10万。临床表现有4型,流感伤寒占95.2%,其中典型病例只占3.92%,误诊量很大。据此认为以往根据疫情报表中的钩体病数来计算的发病率是极不确切的。 |

This survey was carried out from August 1981 to July 1982 at Meng-Lian county, yunnan province, which is located in south subtropic zone.
During this period, 1752 febrile patients were examined and 125 cases of leptospirosis were diagnosed and confirmed by laboratory methods. The annual incidence rate reached 158.83/100,000 and far surpassed the records of past years in this county or other similar regions. Therefore, The incidence of leptospirosis among infectious diseases is only lower than dysentery and malaria in this county. However, the rate varied in locality, season, sex and age of persons. The incidence of plain areas is 526.9/100,000, Semi-mountain areas 97.7/100,000 and the mountain areas 60.3/100,000.The cases of leptospirosis could be seen all the year except January but the highest incidence occurred in August. In male (214.52/100,000) it was higher than in female (102.36/200,000). The age group between 20 and 24 years has the highest incidence (435/100,000).
There are four clinical types, most Cases (95.2%) belong to grippotyphosa type but only 3.92% cases have typical manifestations. Therefore, many cases may be mis-diagnosed and the figure of leptospirosis obtained from the past reports may be less reliable. |
