Just keep a lot of anti-bacterial soap or dish liquid around and wash your hands often, and you won't get sick..Use lysol on doorknobs and other places where people touch often.
Not bad advice, but you might have to add DON'T BREATHE to that list to get full protection.
BTW, I've developed a really nasty sensitization to the Triclosan in those anti-bacterial soaps: Even if immediately rinsed off it causes deeps cracks and dermatitis on my fingers. I really do think it is overused.
I keep Purell hand sanitizer around and in the car. It's pure alcohol and will probably kill anything! Easy to use and dries almost instantly.
Now, I hold my breath when I pass people who cough!! LOL! What did we ever do before the 'flu-shot era'?
