Pilot study to develop an early warning system for emerging infectious diseases in developing countries

进入21世纪，出现了严重急性呼吸系统综合症（SARS）、大流行性流感等新发传染病。与一般容易流行的疾病相比，最近出现的传染病在全球范围内构成了更大的威胁。因此，需要建立一个有效的预警系统，这包括加强日常监测和开发新系统。在这项研究中，我们揭示了积极的病例发现可以保证有效的疫情应对，特别是在流离失所的人群中。此外，在介绍发达国家现有的新方法时，了解各国的背景资料也很重要。为了改善这些情况下的实验室确认，应该开发新的方法，包括基因检测和抗体检测方法。

In the 21st century, there have been newly emerging infectious diseases such as severe acute respiratory syndrome (SARS) and pandemic influenza. Compared with ordinal epidemic prone diseases, recent emerging infectious diseases pose a greater threat at a global level. Therefore it is required to develop an efficient early warning system, which is consist of strengthen of routine surveillance as well as development of new systems. In this study, we revealed that active case findings can warrant an efficient outbreak response especially among displaced population. In addition, it is important to understand the background information in the countries when introducing new methodology available in developed counties. To improve laboratory confirmation in these settings, new methodologies including genetic detection and antibody detection methods shoulde be developed.
