I've expanded on my post.
If we can try and help, yes, but thousands die of flu which spreads like a common cold - and comes with the seasons.
Improved hygiene, hand washing, social distancing. Guess all these measures (and rightly so in regards the first two) will be in place for a long time yet, and that should help bring the spread of stuff like flu down too. Having people having to be tested and traced for stuff like that is a bit much to me.
Anyway, it's common sense? If you get ill, you don't tend to grub about everywhere do you? You're usually in bed and isolating that way.
Of the people that die every year of flu, I imagine it's generally the older, more vulnerable people. Will testing and tracing prevent them from being more susceptible to something like the common cold?
