Highly Pathogenic Avian Influenza A/H5N1 – update and overview of 2006

This is an update of the current situation on Avian influenza. Since 2003, 258 human H5N1 infections have been reported to WHO. Critically, human to human transmission, as indicated by cluster size, is still extremely inefficient. The report states that a nimals are still the source of human infections. H5N1 avian viruses remain poorly adapted to humans. With a high enough viral challenge and perhaps some genetic host susceptibility the viruses can infect humans, in which case they are then often lethally pathogenic, although they are still unable to transmit efficiently between humans.
