Is influenza airborne contact or droplet precautions?
Adherence to precautions. Influenza is usually transmitted through droplet of large particles generated by cough or sneezing of an influenza patient. In some cases, it can spread through smaller aerosols. Droplet can travel less than 1 m, and therefore it is spread by close contact.
Is the flu transmitted through the air?

Are there any airborne viruses?
Airborne viruses are small enough to essentially become aerosolized. An infected individual can emit them through a cough, sneeze, breathing, and talking. In general, most airborne viruses are pretty unstable once they leave the body of their host.
Is flu spread by droplets?
Person to Person. People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
What is the difference between airborne and droplet transmission?
They may also fall on surfaces and then be transferred onto someone's hand who then rubs their eyes, nose or mouth. Airborne transmission occurs when bacteria or viruses travel in droplet nuclei that become aerosolized . Healthy people can inhale the infectious droplet nuclei into their lungs.
Do you wear an N95 for droplet precautions?
A respirator or N95 face mask is NOT necessary but can be used for the care of a patient on Droplet Precautions . Remember, that you should continue to use Standard Precautions during patient care in addition to Droplet Precautions.

How long can airborne viruses stay in the air?
These droplets carry virus and transmit infection. The largest droplets settle out of the air rapidly, within seconds to minutes. The smallest very fine droplets, and aerosol particles formed when these fine droplets rapidly dry, are small enough that they can remain suspended in the air for minutes to hours .
