Thanks for your advice Snare, and I hope you make a quick and full recovery to help others.
I now wonder if/when the authorities will ban all public transport & taxis which are veritable nurseries for such a deadly virus. 'Planes are still bringing thousands of people (untested) from all over the world into Heathrow Airport every day - including from the USA, Italy, China & the far east. https://www.heathrow.com/arrivals
In the UK, If just going for a drive in your car either alone or with your family is dangerous, surely travelling on 'planes and other forms of transport (with air-conditioning!) with strangers is even more so?
