Sneeze particles are in the form of tiny droplets.  They are formed due to pressurized blow and known to contain many viral and infectious bodies.  The reasons for sneeze are many including allergy, viral infection, foreign bodies in the respiratory track and so on.

 

Sneeze particles may not travel longer distance due to their initial speed.  However, since they are very small in size, soon they attain terminal velocity and start drifting in air (just like cloud).  Hence, practically they can travel any distances depending on air current.  When they encounter some substance (may be your friend) they settle down to transfer the infectious information. 

 

In any case, they can not travel faster than computer virus!
