-- today after a deadly strain of the bird flu has killed six people this week.
Health officials in China are working with the Center for Disease Control to find a vaccine.
This -- leading authorities in China to kill more than 20000.
Birds and a live poultry market in Shanghai.
I must have been.
Quite the scene -- some background.
All of this disease has prompted a global health care in 2003.
Bird flu was first detected in Hong Kong back in 1997.
In the past ten years hundreds of cases have been reported in more than a dozen countries some 60% of them -- deadly.
Doctor Mark Siegel is quite a bit about this -- and bachelor book hot headed a professor of medicine and -- -- and of course remember.
Of our Fox News medical -- team doctor Steve -- How are you.
-- great you know I heard from Tom Skinner senior -- per SEC this morning the first thing -- said is I couldn't agree more with this the best treatment for fear is information right and that's on the CDC is looking at this they're preparing -- banks against the possibility they might need a pandemic vaccine is very unlikely.
Because this kind of a bird flu we're talking about doesn't typically cause pandemic it's usually H one -- to user experience.
This is an 87 and nine now what is H mean that's just the protein on the surface of the flu that we -- to identified in the helps the flu spread.
But this is a bird flu and before it could spread easily human to human it would have to change right now.
Even though it's been found in fourteen humans and has killed six in China.
It is not spreading from human to human and that's a very good thing even if -- -- to do that the next thing would be well how easily how many humans are affected.
It's not like the movie contagion where overnight it's certainly spans the globe that does not have.
Does -- -- they killed in -- they think they know where it was coming from I mean I gas and they killed thousands of birds in this area to try to to try to prevent it from spreading further.
How you know how how are good hard day at figuring out whether or not they actually found a source of it.
Well there actually debating right now Martha very important question you're asking.
They don't know whether it's developing a host in mammals right now but they founded in pigeons they looked forward and pigs they haven't found in pigs they founded in pigeons.
They're tracking birds as you said they kill all the birds in the area to prevent spread.
Back in 2005.
With the west bird flu we were worried about the H five -- one that.
Bird flu killed a lot of birds this one seems to be harboring itself in birds but again.
We're talking birds you know how many times I mentioned the word -- here we're not talking human beings.
The problem is when it gets into a human and really infects -- human.
Then a person can get really sick from this and develop some kind of pneumonia but the question is is it going to harbor in the nose and nostrils.
And then be easily spread.
This this thing we need to know people you -- know out there is that the kind of viruses that kill animals are not automatically the same kind of kill people.
People with close contact bird handlers have to watch.
Interesting doctor -- thank you very much good that there's CF seems like.
