Shanghai reports first possible human bird flu death

Many news sources are reporting what could be the first bird flu death in Shanghai. Ms. Li, a 29-year-old migrant worker, "died of pneumonia of unknown causes." The news was first reported on state TV Thursday night. You can watch the report here.

In a well-timed story, Xinhua today is reporting that "H5N1 virus prefers to settle in cells deep within the lungs, rather than in the upper respiratory tract, as happens with human flu strains, two new studies have found. That may help explain why human-to-human transmission of the bird flu virus has so far not happened -- and might not happen in the future."

No word yet on when the Rolling Stones will announce the cancellation of their April gig in Shanghai.
