Interesting article, thanks for posting.
One of my concerns is that the bird flu may mutate enough to give a false negative on testing. Another concern I have is whether or not the tissue sampling was done correctly, because taking tissue from the wrong area can give a false negative as well.
Bleeding in the throat could be from DIC, a bleeding disorder caused by massive infection, or from damage to the throat tissue by caused by the pathogen itself, or from coughing violently, or from medical procedure (such as putting down an airway with severely inflamed tissues).
No way to know.
Yup. Thanks for the insight.
I'll keep an eye on this story as it develops.
