Taiwan reported 23,813 local cases of COVID on Friday and 86 COVID-related deaths. Health officials say the death rate in Taiwan has risen to 0.18%. They also confirmed Taiwan’’s first imported case of the BA.2.75 subvariant. Let’’s hear from the CECC.

We’ve also detected the first case of the BA.2.75 omicron subvariant in Taiwan in a traveler who recently visited India. He is a Taiwanese man in his 30s who had received three vaccine doses. He arrived in Taiwan from India on July 10 with a relative and a friend. All three tested positive in the saliva test carried out upon arrival at the airport. The man’s relative and friend had been infected by the more common BA.4 subvariant. It just shows that over in India, there are many variants circulating. The three developed a fever on July 10, but they all experienced mild symptoms. Their symptoms have all eased and they’ve been released from isolation.

The CECC says the BA.2.75 subvariant was first identified in the world in May. Since then, it has become the dominant strain in India and has been detected in at least 15 countries. The BA.2.75 subvariant has 16 new mutations compared with the BA.2. Eight of them are in the virus’’s spike region, which allows it to evade immunity more easily. The World Health Organization says it does not know yet whether the new variant is more severe.

首例BA.2.75現蹤 30歲男從印度入境驗出

台灣今天新增23,813例本土個案,確診個案中新增86例死亡,致死率上升至萬分之18。同時,台灣也驗出首例Omicron變異株BA.2.75,來聽聽指揮中心的說法。

[[指揮中心醫療應變組副組長 羅一均]]
“在邊境這邊偵測出我們國內首例的BA.2.75,這一個新的Omicron變異株的確定病例,這個是一個印度境外移入的病例,他是住在北部的一個本國籍的30多歲的男性,接種過3劑疫苗,在7/10的時候跟他的一位家人以及一位朋友,一起從印度飛過來台灣這邊,在機場的唾液採檢,3個人都陽性確診,親友的定序都是比較稍微常見一點的BA.4,顯示說在印度這邊,他們是有多病毒同時在流行。3位同行者在7/10這天都有發燒的症狀,不過都屬於輕症,目前症狀都已經緩解,也都解除隔離”

指揮中心指出,BA.2.75變異株最早於今年5月發現,已於印度快速傳播並成為該國主流株,目前全球已有至少15國報告病例。BA.2.75變異株比BA.2多增加16個突變位點,還有8個在S蛋白,具有免疫逃脫特性,恐怕會讓疫苗效力變差,WHO表示尚須研究證實 BA.2.75傳染力及致重症機率。
