AIRBORNE GERM TRANSMISSION

What is AIRBORNE GERM TRANSMISSION?

TRANSMISSION:	When diseases and viruses are transmitted as very small particles by air 
currents, it is called airborne germ transmission. 
		
How do infections spread?

Airborne infections spread when bacteria or viruses travel on dust particles or small 
respiratory droplets that become aerosolized when an infected person sneezes or coughs. 
Healthy people can inhale the infectious droplets, or the droplets can land on their eyes, 
nose and mouth. 

People who inhale the airborne germs do not have to have face-to-face contact or be in the 
same room as the infected person. To protect their patients, hospitals have special air 
handling and ventilation systems in some rooms.

What illnesses are spread this way?

Many respiratory diseases and viruses spread by the airborne route such as: tuberculosis, 
measles and chickenpox.
		
How can one prevent airborne germ transmission?

DPH recommends frequent and thorough hand washing as the most effective way to prevent 
infections. DPH also advises against sharing personal items like drinking cups, eating 
utensils and hand towels. Effective protection measures include covering the mouth and 
nose when coughing or sneezing, and disinfecting commonly used surfaces.
