德爾塔+變種來襲，或更具傳染性

新冠病毒的德爾塔+變種可能是目前世界各地的德爾塔變種之中更具傳染性的變種，正開始向新地區(qū)蔓延。
韓國官員表示，他們已經(jīng)確認了兩例德爾塔+病例，一例是40多歲的男性，“最近沒有旅行史”，另一例最近從美國回國。據(jù)報道，第二例確診病例注射了兩劑阿斯利康的新冠病毒疫苗。
世界衛(wèi)生組織(World Health Organization)將德爾塔+列為“須關(guān)切變種”，6月份在英國首次發(fā)現(xiàn)。此后，美國、印度、中國、俄羅斯和日本等多個國家也發(fā)現(xiàn)了這種病毒。
目前還不確定人們應該如何看待這種變種。有關(guān)這種變體的數(shù)據(jù)仍然在初步統(tǒng)計中的，這使一些衛(wèi)生官員懷疑，將其從“待觀察變種”升級為“須關(guān)切變種”是否為時過早。
據(jù)《印度斯坦時報》報道，截至7月23日，印度共有70例德爾塔+變種病例。在英國至少發(fā)現(xiàn)了39個病例。
德爾塔+變種病毒尚未證明其比德爾塔變種或其他變種病毒更有傳染性。到目前為止，德爾塔+病毒變種的傳播主要發(fā)生在年輕人之中。雖然這些數(shù)據(jù)還處于初步研究階段，但似乎接種疫苗的人體內(nèi)的抗體對這種變種仍然有效。不過，專家警告說，這些發(fā)現(xiàn)可能與真實情況有所出入，因為實驗樣本量仍然很小。
新冠病毒依然肆虐，政府官員們正在密切關(guān)注幾種病毒變種，德爾塔+只是其中之一。（財富中文網(wǎng)）

The Delta Plus variant of COVID-19, which could be an even more contagious mutation of the Delta variant that’s currently infecting people around the world, is beginning to spread to new regions.
Officials in South Korea say they’ve confirmed two cases of Delta Plus, one in a man in his forties with “no recent travel records” and the second from a person who recently returned from the U.S. The second confirmed case had reportedly received both doses of AstraZeneca’s coronavirus vaccine.
Delta Plus, which the World Health Organization lists as a “variant of concern,” was first detected in the U.K. in June. It has since been found in several other countries, including the U.S., India, China, Russia, and Japan.
It’s uncertain at this point how concerned people should be about this variant. Data about the variant is still preliminary, which has led some health officials to wonder if the upgrade from "variant of interest" to one of concern might have been premature.
As of July 23, there were 70 cases of the Delta Plus variant in India, according to the Hindustan Times. At least 39 have been discovered in the U.K.
Delta Plus has not yet shown that its mutations give it a contagion advantage over the Delta variant or other mutations. Infections, so far, have primarily been in younger people. And while the data is still preliminary, it seems that antibodies in vaccinated people are still effective against this variant. Experts warn those findings could shift, though, since the sample size is still very small.
Delta Plus is just one of several variants officials are keeping their eye on as COVID-19 continues to spread.
