I'm glad to hear that "air" has now been added to "hands, face, space" in advice to prevent coronavirus transmission.

If only this advice were followed on public transport.

In spite of the current mild weather, train and bus windows remain closed.

Passengers sit in an unhealthy fug, half stupefied, and very few people seem to have the gumption to open the windows themselves.

I would like to see all windows opened by default by transport staff, and passengers forbidden to shut them - unless the outside temperature is well below freezing.

Everybody is wearing outdoor clothing, and if they feel cold, are probably unwell and should not be travelling.
