Do face masks work? And stop touching your face (but good luck)

Face mask supplies may be limited, but do they even work? And why you should stop touching your face, but that's much easier said than done. On the show today: * Does a face mask really protect you? * How often do we touch our faces? (spoiler: it's a lot) * Can you get coronavirus if an infected person touches fruit and vegetables at the supermarket? * How will hospitals manage if there's huge numbers of people needing care? * And why isolation means isolation. No family members allowed. All that, and a frightening new study which could show how easy it is for a sick person to get coronavirus over everything.
