中國時報【林宜慧╱台北報導】
南韓中東呼吸症候群冠狀病毒感染症(MERS-CoV)疫情不斷擴大,累計至昨早已達50名病例,疾病管制署昨發布病毒初步比對結果,認為韓籍病例的病毒株與以往其他病毒差異不大,變異僅在1%至2%的正常範圍,不影響傳播力。
中國官方從飛往廣東的韓籍病例身上採集到病毒,並將病毒基因公布於國際基因資料庫。
疾管署研檢中心比對美國國家生物技術資訊中心(NCBI)病毒基因庫85株病毒資料,初步認為與其他MERS-CoV病毒同源性相當高;並無基因重組現象,只有小幅變異。
疾管署副署長周志浩表示,小幅變異包括結構蛋白有3個變異,其他則與另85株病毒完全相同;非結構蛋白則有16個胺基酸變異;至於病毒蛋白功能(病毒毒性)是否變異,待進一步了解。

Experts from the World Health Organization and South Korea on Saturday downplayed concerns about the MERS virus spreading further within the country, but said that it was premature to declare the outbreak over.
