Hygiene is a very important aspect when it came to avoiding viruses. Washing your hands throughly before eating is a must. If you cannot wash your hands every time immediately before eating or when just there is just not a lavatory near, then carry one of those hand sanitizer gels that are 99% alcohol, they are better than nothing. Keeping your hands free of viruses are a small step in avoiding catching the flu virus, although is not a guarantee.
