But reluctance, misunderstandings, and false ideas still subsist. Following on from *Clean Hands Save Lives*, this book explains why hand hygiene remains our primary weapon against epidemics, why alcohol is effective, why alcohol-based handrubs and gels are not dangerous, and why their distribution as a common good for humanity could become a model for global health, or even society in general.
When we adapt, we feel invested, concerned, and involved. Nothing matters more for hand hygiene, which protects us and protects others.
