五例境外移入
Taiwan has identified five imported COVID infections of Omicron subvariants.
台灣出現五例由境外移入的Omicron亞型變異株感染病例。
infect(v.)感染infectious(adj.)具有傳染性的contagious(adj.)接觸性傳染的
One of the cases is caused by the BA.4 Omicron subvariant and the others are caused by the BA.5 subtype.
其中一例個案為Omicron BA.4所致，其餘則是Omicron BA.5所致。
subtype=sub-lineage
The new cases include one female and four males in their 30s and 60s who arrived in Taiwan between June 2 and 7.
新增病例包括1名女性及4名男性，年齡介於30至60歲，抵台日期介於6月2日至7日。
test positive or negative 檢測結果為陽性或陰性
The BA.4 infection came from Chile, while the BA.5 infections came from the United States, Turkey and Poland.
其中Omicron BA.4的個案自智利移入，而Omicron BA.5的個案則分別自美國、土耳其及波蘭移入。
The subvariants were first detected in South Africa early this year and they are now fueling a new wave of COVID across countries.
Omicron亞型變異株於今年年初在南非發現，目前導致多個國家疫情升溫。
fuel(n.)燃料；(v.)為～添加燃料
Both of the new sub-lineages are found to be more transmissible than the existing Omicron variants and able to evade antibodies from vaccination and prior infection.
相較於現有的Omicron變異株，兩種新型Omicron亞型變異株均有較高的傳染力及免疫逃脫特性。
transmissible(adj.)具有傳染力的evade(v.)逃脫、躲開、迴避=escape=dodge
Despite this, there is no evidence to suggest these mutations are associated with more severe diseases.
儘管如此，目前尚無證據指出這些變異株會引發重症。
be associated with 跟～有關mild(adj.)輕微的reinfection 再次受到感染breakthrough infection （疫苗未能讓接種者對病毒產生免疫的）突破性感染
The Central Epidemic Command Center said that since the subvariants were detected at the border and were immediately intercepted, they are unlikely to have any impact on the community.
中央流行疫情指揮中心表示，當局在邊境檢測出Omicron亞型變異株，並迅速攔截，因此造成社區感染的機率不高。
intercept(v.)攔截
The CECC also urges people to get vaccinated as the vaccines are effective against existing variants in terms of preventing severe disease, hospitalization and death.
指揮中心也呼籲民眾接種疫苗，因為就預防重症、住院與死亡的方面來看，疫苗仍可有效對抗現有的變異株。
urge sb. to do sth. 呼籲某人做某事vaccinate(v.)給⋯⋯接種疫苗effective(adj.)有效的
