Answer 2

Answer:

rticles and official reports on the new coronavirus are full of terms that most of us don't use daily. Some of them -- Covid-19, for example -- were coined only after the virus emerged in China. Our simple glossary aims to unclutter this specialised vocabulary and help you better understand your news feed. Is there a coronavirus-related term that you'd like to see explained but is not on this list? Let us know in the comments section.

Let's begin.

Coronavirus

You're probably wondering why this is on the list. Well, there are a couple of important things to keep in mind. First, coronavirus isn't the name of any one kind of virus. There's an entire family of coronaviruses -- called Coronaviridae -- and some of them cause the common cold. What we're dealing with now is a "novel", as in new, coronavirus. We didn't know about it until a couple of months ago, when authorities were trying to understand what was causing a cluster of mysterious pneumonia cases in China's Wuhan city. Second, coronaviruses are named for the crown-like effect created by the spike proteins on their surface. "Corona" means crown in Latin.

Covid-19

Short for Corornavirus Disease 2019, this is the name of the disease caused by the new coronavirus. Notice that it doesn't tell you where the virus first emerged. That's not by accident: the World Health Organisation chose a name that would avoid attaching stigma to locations (like China's Wuhan city) or ethniticies. But is that necessary? You bet. Consider the reports of racism targeting Asians or people of Asian origin in the wake of the coronavirus outbreak. [A note on the pronunciation of Covid-19: don't spell the letters out -- say "covid" like a word, followed by the number 19.]
