[Cluster and multiple regression analysis of leptospirosis epidemic factors].
Ten-year surveillance of Rice-field-typed leptospirosis was carried out in high-infected foci. Twenty two parameters of epidemic data were divided into 3 categories and cluster-analyzed. 5 typical variables were selected for multiple regression equation. The equation contained four factors, i.e. rodents density, carriage rates of main animal hosts, GMT of population antibody against leptospira and quantity of rainfall in August. The expected morbidity of leptospirosis calculated by the equation were roughly identical to the real morbidity.
