We then discuss several environmental considerations that influence the airborne transmission of disease, for these greatly impact particular environments in which airborne pathogens are commonly believed to be problematic.
While some experts argue that H5N1 viruses are inherently unable to transmit from human to human, two recent studies of ferrets suggest that airborne transmission is possible (Science 2012;336:1534-41 and Nature 2012; 486:420-8).
