Dr. David Nabarro:

One of my particular concerns is that the people who seem to be most at risk of getting this disease in western Europe and the US are those who are providing services to others, including security guards, cleaners and people driving vehicles, particularly multi-passenger vehicles. I have always felt these are the people who often have less opportunity to negotiate particular aspects of their working and living conditions because they are often poorly paid and may come from ethnic minorities that may have additional challenges.

That is why I was really pleased, for example, in Geneva, when the decision was made to ask all drivers to wear good-fitting face masks for their own protection. I was pleased when I heard talk in the UK that it was going to become mandatory for people to wear masks on London transport and indeed on other urban transport networks, only because I am more concerned about protecting those whose jobs put them into some kind of regular exposure, as I do get very concerned about the inequities around this disease.
