The country cant close down for 6 months as people will need jobs to go back to. Also people need to carry on working or there will definitely be no more loo rolls in the shops. Appreciate it can be fatal for people with pre existing health issues and whilst it has flu like symptoms it is more contagious, but its not the Black Death with a 50% fatality rate.
The answer for me is the at risk people to take all the precautions they can , self isolating if necessary. The rest of us take more care with our personal hygiene and Keep calm and carry on.
