コロナウイルス
解説 Definition
Covid は COVID-19 を短く言う表現で、新型コロナウイルス感染症を指します。ウイルスそのものを指す coronavirus とは区別されることがありますが、日常会話では関連する病気や流行を広く指すこともあります。
An infectious disease caused by the SARS-CoV-2 coronavirus, formally called COVID-19. In informal usage, the term may also refer broadly to the pandemic period and its social effects, but it names the disease rather than the virus itself.
覚え方のコツ Memory Tip
Covid は coronavirus disease の一部を組み合わせた COVID の通常語化した表記で、COVID-19 という病気を指します。virus は原因となるウイルス、Covid はその感染症という区別が核です。have Covid「感染症にかかっている」、during Covid「コロナ禍の間」のような用法を覚え、正式表記 COVID-19 と結びつけましょう。
Remember COVID as a shortened name built from coronavirus disease, with 19 referring to 2019, the year associated with its identification. The most important distinction is that Covid or COVID-19 names the disease, while SARS-CoV-2 names the virus that causes it. In everyday speech, people may say have Covid for the illness or during Covid for the pandemic period and its disruptions. The latter is a broader informal use. Connecting the abbreviation to its full form prevents the common mistake of treating Covid as the precise scientific name of the virus itself.

covid の語源・成り立ち Etymology
COVID は coronavirus disease の頭字語で、2019年発見のため COVID-19 と命名。corona はラテン語で「王冠」を意味し、ウイルス表面の突起が王冠状に見えることに由来。coronation（戴冠式）と同根。
COVID-19 was formed from coronavirus disease and the number 19, referring to 2019. The name was introduced as an official designation for the disease caused by the virus now known as SARS-CoV-2. Coronavirus contains Latin corona, “crown,” because the projecting proteins visible around such viruses resemble a crown. Covid later became a common shorter spelling in general writing, although all-capital COVID-19 remains the formal abbreviated form.
