We've all heard people say 'I won't kiss you, I've got a cold'. But a report just published warns that we may be far more at risk of passing on an infection by shaking someone's hand than in sharing a kiss. A group of hygiene experts from the United States and the UK have published the first detailed report on hand hygiene in the home and community, rather than in hospital and healthcare settings. Their findings are published in the American Journal of Infection Control. They say that, if we want to avoid catching flu or tummy bugs, or protect ourselves and others from organisms such as MRSA, salmonella or C. difficile, then we have to start in our own homes, by paying greater attention to good hand hygiene.
