How is the common cold transmitted from one person to another?
Sneezing is the body’s attempt to rid itself of the virus. When a person who has a cold sneezes, the discharge is full of live viruses and these viruses can live for as long as three hours on surfaces and skin. Since the viruses are microscopic and become airborne after a person who has a cold sneezes and to a lesser extent when they cough, you can inhale the viruses without realizing it.
