"Catch it, bin it, kill it" has been around a lot longer than Covid. We've seen posters carrying the slogan, mainly in the winter, in the UK for years, aimed at people with colds or flu. The Covid-specific government slogan is now on its third incarnation. So far, we've had:
1. Stay home, protect the NHS, save lives.
2. Stay alert, control the virus, save lives.
3. Hands, face, space.
Apparently, #3 is the current one but I'd never heard of it until today when I Googled the slogans for this post.
