據(jù)CNN當(dāng)?shù)貢r(shí)間 8月7日?qǐng)?bào)道，隨著新冠疫情蔓延，美國(guó)已出現(xiàn)去年12月秘魯首先報(bào)告的“拉姆達(dá)”（Lambda）毒株感染病例。

報(bào)道援引全球最大的流感及新型冠狀病毒數(shù)據(jù)平臺(tái)“流感數(shù)據(jù)共享全球倡議”的數(shù)據(jù)顯示，目前美國(guó)已有1060例由“拉姆達(dá)”毒株引起的新冠肺炎病例。

As the coronavirus pandemic continues, infections caused by the Lambda variant have been emerging in the United States.

Genomic sequencing has identified 1,060 cases of Covid-19 caused by the Lambda variant in the United States so far, according to the independent data-sharing initiative GISAID.

CNN報(bào)道稱，目前，美國(guó)新增新冠肺炎確診病例中約有83%均為“德爾塔”變異毒株。雖然現(xiàn)在美國(guó)感染“拉姆達(dá)”毒株的新冠肺炎確診病例數(shù)比感染“德爾塔”變異毒株的病例數(shù)要少的多，但一些傳染病專家表示，“拉姆達(dá)”毒株也是他們正在密切關(guān)注的一種變異毒株。

While that number is a far cry from the surge in cases caused by the Delta variant — representing about 83% of new cases in the US — infectious disease experts have said that Lambda is a variant they are watching closely.

據(jù)央視新聞報(bào)道，世界衛(wèi)生組織今年6月14日發(fā)布報(bào)告，將去年12月最早在秘魯發(fā)現(xiàn)的C.37毒株以希臘字母 λ（拉姆達(dá)）命名，并列為“需要留意”的變異病毒之一（Variant of Interest）。根據(jù)世衛(wèi)組織的標(biāo)準(zhǔn)，如果“需要留意”的變異病毒傳播進(jìn)一步加快，嚴(yán)重到一定程度，如需要為此調(diào)整現(xiàn)有防疫措施等，會(huì)被升級(jí)為“需要關(guān)注”的變異病毒（Variant of Concern）。目前，“德爾塔”變異毒株已被世衛(wèi)列為“需要關(guān)注”的變異病毒。

The Lambda variant was first identified in Peru in December. The World Health Organization designates Delta as a "variant of concern." Lambda is designated a degree lower as a "variant of interest" on 14 June.

據(jù)英國(guó)政府網(wǎng)，此前英國(guó)也已報(bào)告6例拉姆達(dá)變種病例，均與海外旅行有關(guān)。

Six cases of Lambda have been identified across the country to date, all have been linked to overseas travel, according to the UK government.

除美國(guó)和英國(guó)外，日本近日也確診了首例感染“拉姆達(dá)”毒株的患者。

據(jù)《日本時(shí)報(bào)》8月7日?qǐng)?bào)道，日本厚生勞動(dòng)省日前透露，日本確診首例感染“拉姆達(dá)”毒株的新冠肺炎病例。據(jù)悉，這名感染者7月20日從秘魯飛抵日本羽田機(jī)場(chǎng)，在入境檢疫時(shí)被確診新冠肺炎，通過基因分析后確定感染的是“拉姆達(dá)”變異毒株。


The Lambda variant of the novel coronavirus, first identified in Peru, has been found in Japan for the first time, health ministry officials said Friday.

The variant was detected in a woman at Haneda Airport who arrived from Peru on July 20, according to the ministry.

不過，CNN援引美國(guó)傳染病學(xué)會(huì)專家普瑞蒂·馬拉尼（Preeti Malani）的話稱，“目前還很難確定這種毒株的傳染性如何”。馬拉尼還表示，“值得慶幸的是，有研究表明，目前可用的疫苗仍然具有保護(hù)作用。” 

她表示，只要新冠病毒整體沒被控制住，未來就可能出現(xiàn)更多的變異毒株。因此，通過全球廣泛開展疫苗注射等方式控制住新冠病毒的蔓延十分重要。

"Thankfully studies suggest that the currently available vaccines remain protective. We have learned during the pandemic that things can change quickly, so controlling spread of COVID-19 in general will help manage Lambda," wrote Malani, an expert with the Infectious Diseases Society of America. 

"As long as there is uncontrolled spread of SARS-CoV-2, we will see more variants in the future. The only way out is widespread vaccination to control spread and prevent further mutation of SARS-CoV-2. "
