他补充道，该毒株的基因序列很快就会公布。

He added that the genetic code of the virus would be made available soon .

据新闻门户网站越南快讯报道，阮青龙表示，新毒株是在对新近确诊患者进行检测后发现的。

He said it was discovered after running tests on newly-detected patients , online newspaper VnExpress reported .

科学家报告称，德尔塔毒株似乎传播力更强，而且导致更多重症。

Scientists report that it appears to be more transmissible , as well as to cause more serious illness .

病毒会不停地变异，多数变种毒株都无足轻重，但有些变异则会让病毒变得更具传染性。

Viruses mutate all the time and most variants are inconsequential , but some can make a virus more contagious .

世界卫生组织在四月份将德尔塔毒株定性为“待观察变种”，5月11日又将该毒株定性为“须关切变种”。

The World Health Organization designated Delta as a variant of interest in April and a variant of concern on 11 May .

在检测出德尔塔毒株后，津巴布韦政府上周末宣布将在乌伦圭区和卡里巴区实行为期两周的局部封锁。

The Zimbabwean government announced at the weekend a two-week localised lockdown for Hurungwe and Kariba districts after detecting the Delta variant .

报告发现，这种变异病毒的传染性比目前美国的其他毒株高35-45%。

This new strain is 35-45 % more transmissible than other strains of the virus currently in the US , the report found .

根据印度和其他地区所见到的证据，德尔塔毒株似乎会引发更严重的症状，包括腹痛、恶心、呕吐、食欲不振、听力丧失和关节痛。

It appears to cause more severe symptoms , according to evidence seen from India and elsewhere , including stomach pain , nausea pain .

总统菲利克斯·齐赛克迪表示，本国正在暴发第三轮疫情，德尔塔毒株就是元凶之一。

The president , F é lix Tshisekedi , said the country was in the midst of a third wave driven in part by the Delta variant .

尽管卫生系统和免疫规划完善的国家对德尔塔毒株的担心与日俱增，但是最令人担忧的还是德尔塔毒株对贫穷国家的潜在影响。

While concern is mounting in countries with well-developed health systems and vaccine programmes , most worrying is the potential impact of the Delta variant in poorer countries .

主办方还表示，他们正在考虑对来自10个国家的运动员和媒体进行为期6天的强制隔离，在这些国家，最早在印度被发现的变种毒株正在快速传播。

Organizers also said they are considering a six-day hard quarantine for athletes and media coming from the 10 countries where the growth of the variant first found in India is significant .

专家称，去年十月在印度最早发现的名为B.1.617.2的新冠变种毒株比在英国肯特发现的名为B.1.1.7的毒株传染性更强。

The variant of Covid-19 first identified in India last October - called B.1.617.2 - is more transmissible than the UK / Kent variant - also known as B.1.1.7 - according to experts .

美国布朗大学公共卫生学院院长阿施施·杰哈上周将德尔塔毒株称为“迄今为止见过的传染性最强的变种毒株”。

Ashish Jha , the dean of the Brown University 's school of public health in the US , last week called the Delta variant " the most contagious variant we 've seen so far " .

尽管世界各地的卫生部门都在收集和分享关于这一新毒株的传播数据，但是人们担心在那些监测系统不发达的发展中国家，德尔塔毒株的传播范围可能比报告的要广得多。

While health authorities around the world are collecting and sharing data on the spread of the new variant , the fear is that in countries in the developing world with less robust monitoring systems , the Delta variant may already have spread much further than has been reported .

至于该疫苗对变异毒株的有效性，陈薇表示，他们团队在密切关注相关情况，且早已启动针对变异株的疫苗研发，这个疫苗不一定用得上，但宁愿备而不用，不能用而不备。

In regards to the vaccine 's efficacy against mutated strains of SARS-CoV-2 , the virus responsible for COVID-19 , Chen said they are keeping a close eye on the situation and have begun developing vaccines for these new variants . " We may not need these vaccines , but we cannot be caught unprepared . "
