Such storage of virus strains resemble duplicating machines in that we can quickly copy and update any prevailing flu virus on the basis of those established arenas.

In the laboratory, this compound has been able to block the virus -- all the virus strains that we have tested -- from replicating.

I just know he had a stomach virus or flu symptoms last week and sometimes those things stick with you. And when you try to work through them and play at the level that he expects to play at, sometimes you don't let yourself get back (to being) completely healthy.

We have conquered the SARS epidemic in 2003, and we will surely conquer the bird flu virus,

I don't think about duplicating anything.

Bird flu could drive the slender-billed curlew to extinction -- there are very few specimens left and the virus could just be enough to push it over the edge.
