应用集中度研究海南省常见肠道传染病的季节性

The Study on Seasonal Characters of Common Intestinal Communicable Diseases in Hainan Province by Central Tendency

作者运用向量合成表示法——集中度对海南省1983—1992年5种常见肠道传染病的发病时间、频率特征进行统计分析。10年资料统计结果,霍乱集中度最高为0.901,具有较强的月份发病聚集性,9—10月份发病数占全年的84.13%;伤寒和脊髓灰质炎次之,集中度分别为0.502及0.501,有明显的季节性;痢疾及病毒性肝炎虽然集中度低,但也有一定的月发病集中趋势,痢疾于5—8月份发病占全年的43.37%。本文简要分析了5种传染病发病聚集的原因,同时提出了调整肠道传染病防治措施及监测咨询策略,以控制肠道传染病流行及降低发病率。

In this paper, the morbidity time and frequency characteristics of 5 kinds of common intestinal communicable diseases in Hainan province during 1983—1992 were analyzed statistically by means of composition of vectors—central tendency. The statistic results of 10 years' data showed, the central tendency of cholera was the highest one. 0. 901. Cholera cases occurred mainly between Sept. to Nov. , and which constituted 84.13% of all cholera cases in a year. The central tendency of typhoid fever and poliomyelitis were secondary, which were 0. 502 and 0. 501 respectively. The occurrence of typhoid fever and poliomyelitis also had seasonal characteristics. The Central tendency of dysentery and viral hepatitis were less than other three intestinal diseases, but there was also a monthly gathering tendency in the occurrence of dysentery. The dysentery cases occurred during May to August, comprised 43.37% of all dysentery cases in a year. The reasons why these 5 kinds of intestinal communicable diseases occurred centrally were analyzed in this paper. The authors suggested adjusting the preventive and therapeutic methods, as well as the strategies of surveillance and consultation against these 5 diseases, in order to control the epidemic and to lower the incidence rate of these 5 kinds of intestinal communicable diseases.
