The CDC recommended technique for coughing and sneezing is to do it in our sleeves. This website and video aims to educate the public:
The Centers for Disease Control of the U.S. and of several states have put forth posters and public service announcements trying to get people to change the way they cough and sneeze. Only a small fraction of the population has adopted safe techniques. With colds always around the corner, with tuberculosis on the rise, and with bird flu threatening to impair the health and welfare of the nation, all citizens should adopt proper coughing and sneezing techniques.
