Recently, global health and global health surveillance have received unprecedented recognition of their importance because of the newly emerging and reemerging infectious diseases, new cycles of pandemics, and the threats of bioterrorism. The aim of this review is to provide an update of the current state of knowledge on health surveillance in a globalized world. Three key areas will be highlighted in this review: 1) the role of the new International Health Regulations, 2) the emergence of new global health networks for surveillance and bioterrorism, and 3) the reshaping of guidelines for the collection, dissemination, and interventions in global surveillance. A discussion is also presented of the more important challenges of global health surveillance. Global surveillance has been reshaped by important changes in the new International Health Regulations and the rapid development of new global networks for disease surveillance and bioterrorism. These networks provide for the first time at the global scale real-time information about potential outbreaks and epidemics of newly emerging and reemerging infectious diseases. The recent outbreaks of severe acute respiratory syndrome (SARS) and the influenza A (H1N1) pandemic provide evidence of the benefits of the new global monitoring and of the importance of the World Health Organization in its coordinating role in the multilateral response of the global public health community.

全球公共卫生监督的趋势和方向。

最近，由于新出现和重新出现的传染病，新的流行病周期以及生物恐怖主义的威胁，全球卫生和全球卫生监测已受到前所未有的重视。这次审查的目的是在全球化的世界中提供有关健康监测知识的最新信息。这次审查将重点介绍三个关键领域：1）新的《国际卫生条例》的作用； 2）新型的全球监测和生物恐怖主义全球卫生网络的出现； 3）重塑收集，传播和干预措施的准则在全球监视中。还讨论了全球健康监测的更重要挑战。新的《国际卫生条例》的重大变化以及疾病监测和生物恐怖主义新的全球网络的迅速发展，改变了全球监测的格局。这些网络首次在全球范围内提供有关新出现和重新出现的传染病的潜在爆发和流行病的实时信息。最近爆​​发的严重急性呼吸系统综合症（SARS）和甲型流感（H1N1）大流行提供了新的全球监测的好处的证据，也证明了世界卫生组织在其在全球公众多边应对中的协调作用中的重要性健康社区。这些网络首次在全球范围内提供有关新出现和重新出现的传染病的潜在爆发和流行病的实时信息。最近爆​​发的严重急性呼吸系统综合症（SARS）和甲型流感（H1N1）大流行提供了新的全球监测的好处的证据，也证明了世界卫生组织在其在全球公众多边应对中的协调作用中的重要性健康社区。这些网络首次在全球范围内提供有关新出现和重新出现的传染病的潜在爆发和流行病的实时信息。最近爆​​发的严重急性呼吸系统综合症（SARS）和甲型流感（H1N1）大流行提供了新的全球监测的好处的证据，也证明了世界卫生组织在其在全球公众多边应对中的协调作用中的重要性健康社区。
