| 英文摘要 |
The outbreak of severe acute respiratory syndrome (SARS) in March of 2003 that nearly became a global pandemic also hit Taiwan, causing public panic and dealing our economy with an unprecedented blow. In December the same year, avian influenza also broke out in Korea, Japan and Vietnam. Since then, countries around the world have also reported all kinds of subtype high/low pathogenic avian influenza cases. There was large-scale H1N1 pandemic on the global scene in 2009. Subsequently, fatality cases of humans infected with H5N1, H7N9, and Middle East Respiratory Syndrome Coronavirus have also been reported, which attracted worldwide attention and concerns and caused considerable panic worldwide. For the early detection of unusual outbreak or emerging infectious diseases so prompt control measures can be implemented, CDC, adopting the concept of clustering event, established a symptom surveillance system for the reporting of cases with identical symptoms. |
