How is Influenza Transmitted in Humans? A Systematic Review
Dr Gardam's systematic review included much of the same literature on survival of influenza in the environment, on experimental infections in laboratory animals and in humans, and epidemiological studies of outbreaks as that reviewed by the Queen's University team. (This paper is now in press in Lancet Infectious Diseases)He concluded that:
* The literature supports the idea that close contact is required for transmission to occur. Whether this occurs through droplet, contact, or indirect contact is unknown.
* The literature does not support transmission over long distances. Although there is no evidence that long-distance (airborne) transmission occurs, this has not been conclusively ruled out in the current literature. It was further concluded that if this type of transmission occurs, it is rare.
* There are no data in the literature to define the conditions under which influenza might become opportunistically airborne, (i.e., during a bronchoscopy).

One little link from a few years back? Come on you can do a little better than this can"t you? Google is your friend, give it a try
Flu Transmission
"Transmission via contaminated hands and fomites has been suggested as a contributing factor in some studies. However, there is insufficient data to determine the proportion of influenza transmission that is attributable to direct or indirect contact..."
There is no evidence that influenza transmission can occur across long distances (e.g., through ventilation systems)

there would probably be some percentage of people who would be immune-and I reckon on an island somewhere if they didnt have contact maybe
Transmission of influenza occurs between
aerosol-infected animals and healthy animals
• Mice physically separated by a ¾ inch double
mesh-wire screen
• Ferrets housed in separate wire-meshed cages
• Ferrets separated by approximately 8 foot long
“S” and “U”-shaped closed ducts

Droplet nuclei (airborne) transmission entails the production of infectious droplet nuclei, generally 5 micrometers or less in diameter. In contrast with larger droplets, these droplets can remain suspended in the air and be disseminated by air currents in a room or through a facility to be inhaled by a susceptible host. Small droplet nuclei and aerosols can remain suspended in the air for prolonged periods and travel significant distances. Small particles appear to be more infectious, with both the degree of infectivity and the severity of illness and is directly related to particle size. Aerosols smaller than 10 microns have been shown to cause more severe disease and require a smaller inoculum than large intranasal droplets.

Your own source says it can....
Through 8 feet of ducting!
Can't be clearer than that mate.
