登革热预警指标的探讨

登革热是全球范围内重要的公共卫生问题，其发生具有突然性、传播迅速、发病率高的特点，极容易在没有任何防备的情况下发生大规模的爆发、流行，演变成严重的突发公共卫生事件或国际关注疾病。1978年以来，我国南方一些省份几乎每年均发生不同程度的爆发、流行，而且登革热的重要传播媒介白蚊伊蚊在我国多数地区分布广泛，因此，登革热的防制将成为今后相当长时间内的重大公共卫生问题．为了防止该病的地方性流行趋势和流行范围的不断扩大，建立登革热预警系统和指标体系十分重要，本文将对登革热的预警指标体系作一简要探讨，为登革热的防制提供理论依据。

Discussion on index of dengue fever warning

Dengue fever is an important public health problem in the world. Its development has the characteristics of unexpectness, fast dissemination, high incidence rate, and large-scale outbreak. The epidemic can easily happen without any precaution, developing into serious public health emergencies or diseases of international concern. Outbreak of dengue fever almost happens every year in some southern provinces of our country from 1978, and Aedes albopictus which is an important transmission vector of dengue fever, distributes very widely in majority of regions in our country, therefore, the prevention and control of dengue fever will become a grave public health concern in a quite long time in the future. It is very important to build early warning system and index system to prevent the endemic trend and the enlargement of epidemic scope. This review discusses dengue fever warning index system and provides theoretical foundation for the prevention and control of dengue fever.
