Well, instead of saying corona you can call it covid19, here I'm explaining you in brief what actually it is
Why it named covid19
My (slightly educated) guess is that it stands for COrona VIrus Disease, and I know that there are many other Corona Viruses out there, mostly causeing the common cold, and that this is #19 that they’ve discovered.
ETA: No, actually, 19 refers to its naming on December 31, 2019.
Detail about covid19
It’s the new viral disease caused by the novel SARS CoV-19 virus, it causes cough, sneezing, fever, diarrhea, those who are more ill develop a viral pneumonia people can die of, overal mortality in general is 2,3%, higher in males 2,8% than in female 1,7%, higher in the elderly: in those <50 yo <0,5%, in those >80 yo approaching 15%. 80% of those infected aren’t sick, but are infectious anyway, thus makes recognizing who is infected so very, very hard. Infection is by droplets of saliva containing the virus formed when coughing and sneezing, all those who cough and sneeze should wear a simple facemask to prevent saliva droplets from reaching other people.
