Watch this funny video to learn about where you should be coughing. Just say no to using your hands.

I have to say that I've started coughing and sneezing into my sleeve in the recent years and discovered that the only side effect is that every once and a while I get a little glob of snot on my sleeve. GROSS! But hey, who really washes their hands every time they cough, sneeze, or touch their face? So sacrifice a little snotty fabric and cough and sneeze into your sleeve.
