再见，B.1.1.7、B.1.351 和 P.1。
Hello Alpha, Beta and Gamma.
The World Health Organization (WHO) announced May 31 that it has given new names to the several versions, or variants, of new coronavirus spreading around the world. Based on Greek letters, the names are simple and easy to remember.
The international health agency recognized that the scientific names can be difficult to say. It said, "As a result, people often resort to calling variants by the places where they are detected, which is stigmatizing and discriminatory."
As early as 2015, the WHO had advised scientists, officials and the media to avoid naming new infectious diseases after people, animals and places. It said to avoid names like Middle East Respiratory Syndrome, Spanish Flu, or Legionnaires Disease, which have since become part of medical history. Instead, the WHO said, names should be descriptive terms based on general symptoms, or signs of sickness, caused by the disease.
Dr. Keiji Fukuda was WHO Assistant Director-General for Health Security at the time. He said, "This may seem like a trivial issue to some, but disease names really do matter to the people who are directly affected." He noted that disease names of the past have caused damage to economies, trade, and members of religious or ethnic communities.
Last month, Agence-France Presse reported that the Indian government ordered the country's social media to remove all writings that referred to the "Indian variant." The government said the term could suggest India was to blame for the disease.
The WHO says it will continue to use the scientific name SARS-CoV-2 to describe the coronavirus that was first identified in Wuhan. The disease it causes is still called coronavirus disease 2019, or COVID-19. And scientists will continue to use the difficult-to-remember names of the variants in their research.
世卫组织表示，将继续使用学名SARS-CoV-2来描述最早在武汉发现的新冠病毒(注：最早发现并非指病毒源头)。它引发的疾病仍被成为coronavirus disease 2019或是COVID-19。科学家们还将继续在他们的研究中使用那些难以记住的变体名称。
For the public, the variant first identified in Britain will now be called Alpha. The one first identified in South Africa will be known as Beta; the one in Brazil as Gamma; and the one in India as Delta.
As new variants of concern and of interest are identified, the WHO said it will work with experts to name them after Greek letters.
