中文摘要 | 登革熱近 10年確定病例發生率為我國急性傳染病之冠,且近 3年每年採檢送驗人數均超過 1萬人;為更有效運用防疫資源,故進行登革熱確定病例擴大疫調採檢效益評估。經分析 2009-2011三年間登革熱通報、確定病例及擴大疫調採檢者等資料發現:(一)平均每年約通報 3,400例登革熱,其中約 1,500例研判確定,通報來源以醫療院所通報為主,其次為擴大疫調採檢陽性者(亦即法傳通報系統個案來源中之接觸者轉個案);(二)每年登革熱採檢人數約 15,700人,其中通報個案採檢人數約 3,370人(21.5%),疫調採檢人數約 12,330人(78.5%),前者陽性率46%為後者陽性率2.0%的23倍;(三)確定病例擴大疫調採檢數超過 100例者低於1%,雖該等採檢數占總採檢數的 16.4%,但採檢陽性率僅 0.7%,顯著低於擴大疫調總採檢陽性率 2.0%;(四)擴大疫調有症狀者檢驗陽性率為無症狀者之 1.8~41.5倍。本研究顯示,2009-2011年,擴大疫調總採檢陽性率僅2.0%,醫院通報陽性率為39.9%;亦即擴大疫調每檢出一例確定病例所需成本,為醫院通報檢出確定病例的 20倍。故如需進行擴大疫調採檢,應採檢有疑似症狀、或有疑似群聚可能性、或曾有流行地區旅遊史之病例效益最大,並儘量避免以地毯式採檢之檢驗結果,作為防治措施成果之展現。 |
英文摘要 | Dengue fever, with the highest incidence rate of confirmed cases in the last ten years, is the most common acute infectious disease in Taiwan. Annually more than ten thousand people had their samples collected and tested for the dengue virus over the past three years. In order to apply dengue prevention resources more effectively, this article reviewed the expanded epidemic investigations which was conducted between 2009 and 2011. Through the data collected from notificable surveillance system and expanded epidemic investigations, the results indicated the followings: (1) an average of 3,400 suspected dengue cases were reported each year, with 1,500 confirmed cases. Most of cases were reported by medical clinics or hospitals, followed by positive cases through expanded investigations (positive contacts from dengue confirmed cases); (2) an average of 15,700 people were tested for dengue virus each year. Among them, 3,370 (21.5%) came from the surveillance system, while 12,330 (78.5%) came from expanded investigations. The former group had a positive rate of 46%, which was 23 times compared to the later group (2%); (3) less than 1% of dengue confirmed cases collected over 100 contacts through expanded investigations. Although those contacts are 16.4% of the totals, yielded a positive rate of 0.7%, much less than the overall rate of 2%; (4) through expanded investigations, contacts with symptoms were 1.8 to 41.5 times more likely to have a positive result than asymptomatic contacts. This study showed that only 2% of contacts collected from expanded investigations tested positive from 2009 to 2011, while 39.9% of the cases reported by medical clinics or hospitals tested positive. Each positive case through expanded investigations was 20 times more costly than a case identified through reporting source of clinics or hospitals. Because of the high costs associated, expanded epidemic investigations should be conducted on people who have dengue-like symptoms, or possible dengue clusters, or who have travelled to epidemic areas, for the best results. Large-scaled mass investigations should be discouraged during outbreaks. |
