Abstract

Circular distribution was used for statistical analysis of the data collected through a three-year period in county X, Hubei Province, to find out the seasonal characteristics of epidemic cerebrospinal meningitis, epidemic encephalitis B and malaria. The method provided a summary in the detection of the epidemic peak of one or several diseases in different years and was also useful in determining the epidemic time focus of a disease. Therefore, it may serve as a scientific basis for the prevention of certain diseases and an accurate means for the statistical management of the data obtained in seasonal epidemic diseases.
