I remember when this news broke 2 years ago. I was on holiday in Taiwan and after the news report on television about the WHO announcement, I thought “how can they not know exactly what this virus is but can be so sure that there’s no human-to-human transmission?”

Well, obviously my concern at the time turned out to be well-justified. How this virus has caused havoc around the world in the last 2 years?!
