This variant, which first appeared in South Africa in November 2024, earned its nickname because it seemed to remain dormant like an insect before resurfacing in late 2025.

此變異株於2024年11月首次出現於南非,因為它好像昆蟲一樣,在2025年末重新浮出水面之前曾處於休眠狀態,因此獲得了這個綽號。

As a descendant of the Omicron family, BA.3.2 is genetically distinct and highly mutated, with 70 to 75 changes in its spike protein.

作為Omicron家族的後代,BA.3.2在基因上獨特且突變程度極高,其棘突蛋白發生了70到75處變化。

While this has raised concerns about potential immune escape, experts note that vaccines likely remain effective against severe illness.

儘管這引發了人們對潛在免疫逃逸的擔憂,但專家指出,疫苗對預防重症仍然有效。

Currently, BA.3.2 is a minority strain worldwide, though it has been detected in over 20 countries and is present in at least 25 U.S. states through wastewater surveillance.

目前,BA.3.2在全球屬於少數毒株,儘管已在20多個國家被檢測到,並通過廢水監測在至少25個美國州份出現。
