Wow, talk about a blast from the past. The last time I've read this one, nobody has ever heard of a "coronavirus" before...
I hate to nitpick but SARS was 2002.
It was a colorful exaggeration. I am aware that epidemiologists have been studying coronaviruses since the 1930s, I was merely pointing out that the previous update of this manga's translation was published several weeks before the novel coronavirus later designated COVID-19 was reported to the CCDC, much less to the general public.
Jokes are like frogs. :-)
