May 9 Flu Update--back in the saddle

Recombinomics with the seminal question on recombination and mutation.

Such concern was easy to understand. Increased efficiency in human-to-human transmission of a recombinant virus that produces milder disease is the formula for a pandemic. It creates more hosts for more dual infections and more recombinants. H5N1 in humans offers more chances of a human being infected with H5N1 and H3N2, which could undergo a recombination similar to the one described earlier. However, this time the human receptor binding domain in H3N2 could be acquired. The recombinant H5N1 could achieve the type of efficiency seen in human flu viruses, which are almost impossible to control.

These changes of course set the stage for more recombination, when more humans are infected, and the H5N1 that has a 100% case fatality rate in southern Vietnam and Cambodia is still circulating. The greater the number of dual infections, the greater the chance of more recombination.

This leads to a greater chance of a recombinant with efficient transmission combined with a high case fatality rate to create a pandemic rivaling 1918.
