So far, no sustained human-to-human transmission of the H5N1 virus has been identified, and no evidence for genetic reassortment between human and avian influenza virus genes has been found;
Also from the CDC website:
Infection: The virus does not typically infect humans. In 1997, however, the first instance of direct bird-to-human transmission of influenza A (H5N1) virus was documented during an outbreak of avian influenza among poultry in Hong Kong; the virus caused severe respiratory illness in 18 people, of whom 6 died. Since that time, there have been other instances of H5N1 infection among humans (see Avian Influenza Infection in Humans). However, H5N1 viruses thus far have not been capable of efficient human-to-human transmission; health officials continue to monitor the situation closely for evidence of H5N1 transmission between people.
• Spread: Infected birds shed virus in saliva, nasal secretions, and feces. Avian influenza viruses spread among susceptible birds when they have contact with contaminated excretions. It is believed that most cases of H5N1 infection in humans have resulted from contact with infected poultry or contaminated surfaces.
The bottom line is that Bill"The Sky is Falling"Moyers" seems to have de-emphasized the fact that the H5N1 virus is not now capabable of the kind of human-to-human transmission, that would make it a threat for a Pandemic, and there no evidence that the genetic reassortment that is necessary for this to occur is taking place.
It does make a better story if you leave that out--
