This 2009 photograph captured a sneeze in progress, revealing the plume of salivary droplets as they are expelled in a large cone-shaped array from this mans open mouth, thereby, dramatically illustrating the reason one needs to cover hios/her mouth when coughing, or sneezing, in order to protect others from germ exposure.
How Germs Spread
Illnesses like the flu (influenza) and colds are caused by viruses that infect the nose, throat, and lungs. The flu and colds usually spread from person to person when an infected person coughs or sneezes.
How to Help Stop the Spread of Germs
Take care to:
– Cover your mouth and nose when you sneeze or cough
– Clean your hands often
– Avoid touching your eyes, nose or mouth
– Stay home when you are sick and check with a health care provider when needed
