This virus is very interesting for us because it's causing
such different symptoms in birds and humans.
Since this is causing no symptoms
in the birds it's flying under the radar screen so to speak.
Which means that it might be more wide spread
than we realize.
That's one of the major concerns for the Americas
because it's not here, it's not established in our birds.
The Chinese released sequences
for the first four human cases very quickly.
There's a lot you can learn just
from getting the sequence information that can lead you
on to other experiments and possibly field studies to try
to confirm the suspicions you develop from the sequences.
We know a lot about the virus just from the sequence
but it's also got some changes we don't really understand yet.
Which tells us there's still a lot to learn about this virus.
So, we have to actually work with it in the laboratory
to figure these things out.
This one is showing a lot more human cases early on.
H7 compared to H5.
Since everybody is experienced with having
to change the vaccine composition
for seasonal influenza every year,
we know that influenza viruses can change.
That's something we have to be aware of we have to see
that we have a vaccine that works against what's
in the population at the time.
We're doing as much as we can
and our people are working very hard
and they know what they're doing.
They're producing results at an amazing speed.
