Naming the coronavirus disease (COVID-19) and the virus that causes it
Official names have been announced for the virus responsible for COVID-19 (previously known as “2019 novel coronavirus”) and the disease it causes. The official names are:
Disease: coronavirus disease (COVID-19)
Virus: severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)

※WHOのテクニカル・ガイダンスより
To be clear, Covid-19 refers to the disease. “Co” refers to corona, “vi” to virus, and “d” to disease. The virus that causes the disease is SARS-CoV-2, which was named by the International Committee on Taxonomy of Viruses. The “SARS” part of the name refers to the new coronavirus’ genetic link to the virus that caused the 2003 SARS outbreak. So one tests positive for SARS-CoV-2, not Covid-19, as it’s the virus and not the disease that does the infecting.

At a press briefing on Feb. 13, WHO executive director Michael Ryan noted that SARS-CoV-2 is a technical term for virologists in labs, while Covid-19 is a term for the average person. “We’re trying to relate the virus to the world, the experience that people have with the virus… so I don’t think there’s any inconsistency,” he said.

※「一般人レベルならウイルスのことをCovid-19と呼んでも構わない」というのがWHOの方針。話が混乱するからこういう方針はやめてほしかったんですが*1。
In journals like the Lancet and the New England Journal of Medicine, scientists use both “Covid-19” and “SARS-CoV-2” to refer to the disease and virus respectively, but never the WHO’s term “Covid-19 virus.”

2020年2月11日、国際ウイルス分類委員会 (ICTV) がSARS-CoV-2（Severe acute respiratory syndrome coronavirus 2 の略称）と命名した。……日本では単に「新型コロナウイルス」と呼ばれる。
