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.
