What scares me is that this could happen and this could happen so easily”

….air flowed into the next cage. killing all 40 exposed ferrets.

The above comments are from an ABC news video report on the H5N1 transmission experiments by Ron Fouchier in the Netherlands. His quote above highlights his concerns and the second comment highlights the level of lethality seen for the H5N1 that was used to infect one of the ferrets which maintained its high level of lethality after acquiring the full set of 5 changes in 2 genes. This level of lethality was in marked contrast to experiments by Yoshi Kawoaka which also achieved efficient transmission in ferrets but failed to kill at levels higher that H1N1pdm09, which was used as a genetic background for the H5 gene.
