In March 2003, Taiwan was hit by the global outbreak of severe acute respiratory syndrome (SARS); panic ensued, causing unprecedented damage to our economy. In December of the same year, Korea, Japan and Vietnam reported outbreaks of avian flu. With the exceptions of Taiwan and Pakistan, all other Asian nations have become avian flu endemic regions. Furthermore, in Vietnam, Thailand and Cambodia, cases of human death resulting from the H5N1 virus infectious have caused concern and global panic. To prevent the virus from entering Taiwan, the Symptom Surveillance System has been formed to facilitate early detection of SARS (discontinued in 2005) and of H5N1 infections so that necessary response and epidemic prevention measures may be enacted. Furthermore, in 2006, several active surveillance systems were integrated. To date, surveillance categories include cases matching symptoms of persons-under-investigation for Novel influenza, influenza-like illnesses, fevers of unknown etiology, diarrhea, coughs that persist for more than three weeks, upper respiratory tract infections and enterovirus infection cases. |
