Sneezing can spread countless illnesses. It is common courtesy
to cover
your sneeze in order to prevent the people in your 15 foot infection
radius
from getting sneezed upon.
The Hand Cover:
Covering your sneeze with your hands is just about the worst sneeze
cover; other than not covering it at all. Sneezing into your
hand is
automatically premeditating infection to others. If you were
to wash
your hands immediately after sneezing you would still need to
touch
multiple objects including door handles and faucets. The
infection radius
for the hand cover is unattainable because you infect a person
every
time you touch a common object. By covering a sneeze
with your hand,
you are allowing tiny fast streams of mucous filled air currents to
flow
through the cracks in your hand.

Pressure Difference for the Hand Cover:
Pressure (P) is related to the force over a certain amount of
area: P=F/A
For a sneeze, there is a pressure difference between an uncovered
sneeze and a hand covered
sneeze. In
the equation: Pv=nRT,
the only difference in sneeze coverage is how much pressure
changes after the sneeze is expelled.
The sneeze pressure difference can be expressed as the
ratio of force of the sneeze and area of the sneeze that is expelled
with out covering
your sneeze (1) and with covering your sneeze with your hand (2):
F1/A1=F2/A2
This
equation shows that increasing sneeze coverage therefore decrease
the force expelled by the sneeze
