In recent years, problems like insufficient coordination, low efficiency, and heavy working load in national communicable disease surveillance systems in China have been pointed out by many researchers. To strengthen the national communicable disease surveillance systems becomes an immediate concern. Since the World Health Organization has recommended that a structured approach to strengthen national communicable disease surveillance must include an evaluation to existing systems which usually begins with a systematic description, we conducted the first survey for communicable disease surveillance systems in China, in order to understand the situation of core and support surveillance activities at province-level and county-level centers for disease control and prevention (CDCs).
A nationwide survey was conducted by mail between May and October 2006 to investigate the implementation of core and support activities of the Notifiable Disease Reporting System (NDRS) and disease-specific surveillance systems in all of the 31 province-level and selected 14 county-level CDCs in Mainland China The comments on the performance of communicable disease surveillance systems were also collected from the directors of CDCs in this survey.
The core activities of NDRS such as confirmation, reporting and analysis and some support activities such as supervision and staff training were found sufficient in both province-level and county-level surveyed CDCs, but other support activities including information feedback, equipment and financial support need to be strengthened in most of the investigated CDCs. A total of 47 communicable diseases or syndromes were under surveillance at province level, and 20 diseases or syndromes at county level. The activities among different disease-specific surveillance systems varied widely. Acute flaccid paralysis (AFP), measles and tuberculosis (TB) surveillance systems got relatively high recognition both at province level and county level.
China has already established a national communicable disease surveillance framework that combines NDRS and disease-specific surveillance systems. The core and support activities of NDRS were found sufficient, while the implementation of those activities varied among different disease-specific surveillance systems.
近年来，许多研究人员指出中国国家传染病监测系统存在协调不足、效率低下和工作负荷过重等问题。加强国家传染病监测系统已成为当务之急。由于世界卫生组织建议，加强国家传染病监测系统的结构化方法必须包括对现有系统的评估，通常从系统描述开始，因此我们对中国的传染病监测系统进行了首次调查，以了解省级和县级疾病预防控制中心（CDC）的核心和支持监测活动的情况。
2006 年 5 月至 10 月，通过邮件对全国 31 个省级和中国大陆选定的 14 个县级 CDC 进行了全国性调查，以调查传染病报告系统（NDRS）的核心和支持活动以及疾病特定监测系统的实施情况。本调查还收集了 CDC 主任对传染病监测系统性能的意见。
NDRS 的核心活动，如确认、报告和分析以及一些支持活动，如监督和人员培训，在省级和县级调查的 CDC 中都被认为是充分的，但在大多数调查的 CDC 中，其他支持活动，包括信息反馈、设备和财务支持，需要加强。省级共监测传染病或综合征 47 种，县级监测 20 种。不同疾病特定监测系统的活动差异很大。急性弛缓性麻痹（AFP）、麻疹和结核病（TB）监测系统在省级和县级都得到了较高的认可。
中国已经建立了一个国家传染病监测框架，结合了 NDRS 和疾病特定监测系统。NDRS 的核心和支持活动被认为是充分的，而这些活动在不同的疾病特定监测系统中的实施情况有所不同。
