Well, it looks as if this bird flu and the 1918 flu are somewhat related.

But the findings, to be published Friday by the journal Science, do highlight how important it is to monitor avian flu - because the research suggests it might take fewer genetic adaptations than once thought for a bird virus to begin spreading from person to person.
The research, conducted separately by scientists at the Scripps Institute in La Jolla, Calif., and at Britain's Medical Research Council, used lung samples preserved from victims of the 1918 flu to reconstruct a protein crucial to their infection.
"These were not little steps but big strides toward understanding, at the structural and molecular level, what it is about these strains that make them dangerous," said Dr. Gregory Poland, a flu specialist at the Mayo Clinic who reviewed the research.
The findings don't completely explain the 1918 strain's virulence, cautioned Michael Perdue, who investigates avian flu at the Agriculture Department's Agricultural Research Service. Other factors than the protein studied, called hemagglutinin, play a role too, he said.
But "this would put together several pieces" of that puzzle, Perdue said. Also, "it suggests the potential is certainly there for rapid transition from an avian to a mammalian strain."

QUOTE
The World Health Organization said the bird flu virus that killed two Vietnamese sisters did not contain human genes, meaning there is still no sign the virus sweeping Asia has mutated into a new, more contagious form.
The women's blood was tested because experts suspected they may have caught the disease from their brother, who also died; but that link could not be proven because the brother's body was cremated. So far, there have been no known cases of person-to-person transmission in the current bird flu outbreak.
Health experts have been most worried about the possibility of the disease combining with the human influenza virus to create a more lethal version that could be spread between people - giving rise to a global pandemic.
The new data is "reassuring" evidence that the H5N1 bird flu virus that's hitting Asia has not acquired that ability, the WHO said in a statement posted on its Web site late Friday.
