In at least one of the outbreaks, an airborne transmission
hypothesis was proposed (Li et al.
The potential role of airborne transmission
of Salmonella is not clearly defined.
of influenza A/H5N1 virus between ferrets.
There are different pathways of pathogen transport such as direct contact with an infected person or as airborne transmission
or a combination of pathways.
A mutation that helped enable airborne transmission
of the H5N1 flu virus between ferrets nearly obliterates the ability of the virus to latch onto avian cells.
Disease dynamics are simulated using a susceptible-exposed-injector-removed infection modeling approach, with the contact rate due to airborne transmission
incorporated through coupling with the Wells-Riley model.
But, the filter was later found to have an effect in reducing the airborne transmission
of bacteria such as MRSA (methicillin-resistant Staphylococcus aureus) and Clostridium difficile.
Though there is no evidence of airborne transmission
, there are still fears that it could mutate into a strain capable of human-to-human transmission.
Using epidemiologic data and computer modeling, researchers in Hong Kong concluded that airborne transmission
was responsible for the spread of SARS-CoV during the large community outbreak in the Amoy Gardens housing complex last March.
Influenza is spread mainly by airborne transmission
or contact with oral secretions, said Dr.
did not occur with the five other avian viruses tested, but two of the viruses spread in ferrets that shared cages.
T156A abrogates a TV-glycosylation site and, when together with S223N (not found in A/Alberta/01/2014), may improve virus replication in the upper respiratory tract of ferrets (9); T156A is consistently found in ferret-adapted mutants capable of airborne transmission
is a known route of infection for airborne diseases such aspergillosis, Legionnaire's, tuberculosis, smallpox, influenza, varicella and measles (Beggs, CB 2003).
In June, researchers described in two controversial papers how easily bird flu can be mutated to render it capable of airborne transmission
Although fewer than 15% of hospital- acquired infections are directly attributable to airborne transmission
, more than one-third may be caused by surface microbes aerosolized by the movement of air from building systems, people, and equipment.
