@ofwarren indeed - those who are more vulnerable need those who aren't to take sensible precautions against the virus.
My colleague who has travelled back from a country with a substantial number of cases, but for which the official advice is to only self-isolate if symptoms develop, has opted not to come into work today.
We're waiting for the final decision in whether he will come in as usual in the next 2 weeks. Most people are relaxed about it ('more people die of flu'). Some people who have underlying health concerns, like me, have suggested keeping him away to reduce our risk. My ability to work from home is limited over the next few days, but if colleague does come in I will aim to avoid him as much as as I can.
I am fed up of people who enjoy good health dismissing the concerns of people who are more at risk.
On the positive side I've noticed increasing numbers of people washing their hands properly at work and when out and about. So the message about basic hygiene is getting out here at least.
