PHILADELPHIA (CBS) -- Have you ever had a flu or stomach virus that was just "going around" and wonder why you got it and others didn't?

It all comes down to luck and exposure in many cases. For instance for the past few weeks there has been a respiratory system infection that has been causing people to cough and sneeze and is associated with mucus build up and congestion. All it takes is someone coughing on you or perhaps touching a contaminated counter and biting your nail or touching your eyes.

So what can you do? Nothing is perfect but study after study has shown wash your hands. If you do this on a consistent basis it will make a difference.
