2 天前 · 英國《衛報》 報導 ,新冠肺炎出現變種病毒「B.1.1.529」,其刺突蛋白上有32個突變,可能影響病毒的傳染能力與帶來的症狀,目前共通報10起案例。 該病毒首先於11月11日在非洲內陸國家波札那發現,三天後南非又測到該國最早的「B.1.1.529」病例。 近來香港從一名36歲男子身上驗出,他在飛往南非前PCR檢測結果為陰性,10月22日至11月11日逗留南非,其後返港第一次篩檢呈現陰性,但在13日第二次篩檢呈現陽性結果。 B.1.1.529 #NuVariant mutations: - K417N & E484A, more able to dodge vaccines. - N440K & S477N are linked to antibody escape.
2024年3月20日 · All sub-lineages of the listed lineages are also included in the variant, e.g., B.1.429.1 is included in B.1.427/B.1.429 as it is a sub-lineage of B.1.429. (a) No assessment of transmission is given for variants in the monitoring category, only detected/not detected.
2 天前 · Background: Omicron (B.1.1.529), a variant of SARS-CoV-2, has emerged as a dominant strain in COVID-19 pandemic. This development has raised concerns about the effectiveness of vaccination to Omicron, particularly in the context of children and adolescents.
2024年3月9日 · 南非科學家檢查豪登省的檢測數據,他們發現B.1.1.529變異株的特性可能是造成病例急速增加的原因。新冠肺炎病患中,因B.1.1.529變異株染疫的比例在數週內上升到90%;南非的單日新增染疫人數在11月初僅有106人,24日卻遽增逾10倍到1,275人。
2024年3月7日 · After the Delta wave subsided in late 2021, the newly named Omicron (B.1.1.529) began to quickly spread across the globe. However, unlike previous variants that quickly took dominance over other variants, Omicron quickly mutated and began co-circulating with its own subvariants.
