Via The Global Dispatch, an item about an interview today on Outbreak News This Week Radio Show: Talking bird flu, seasonal influenza, flu shots and India’s polio success with Dr. Vincent Racaniello. Excerpt:
Racaniello talked about H5N1 avian influenza symptomology and when asked, “What is this virus missing that keeps it from being implicated in person-to-person transmission?”, Racaniello said, “That’s the million dollar question.”
“As far as we know, only H1, H2 and H3 influenza viruses can transmit well person to person”.
Racaniello gives a lengthy story on a theory on why one seasonal flu strain predominates one year and not the next, definitely worth a listen.
How do health authorities figure out what flu strains to incorporate into the seasonal flu shot? Racaniello explains the process.
He also talks about the incredible and once thought impossible thing that happened recently in India–no polio cases in three years!
