I think you're right Major West. Getting on for half a million deaths is unthinkable. However, as I understand it, viruses are simple stands of DNA in a protective shell, and have the ability to mutate relatively easily. That's why the flu strain tends to be different each winter. If (and it's a big if) the current coronavirus mutates into a more virulent form, then the number of casualties could quickly escalate. That's one of the major risk identified by the World Health Organisation. If you think the WHO are being alarmist, google 'Spanish Flu'. Let's hope, come the warmer weather, it dies out, as happened with SARS.
