July 8 Flu UpdateHong Kong has scaled back its bird flu alert with the absence of cases.
An article published recently in a medical journal says that the mutations needed for H5N1 to go H2H have been identified.
"The mutations needed for the emergence of a potential pandemic virus are likely to originate and be selected within infected human tissues," said Professor Dr Prasert Auewarakul from Mahidol University, Thailand. "We analyzed specific molecules called haemagglutinin on viruses derived from fatal human cases. Our results suggest new candidate mutations that may allow bird flu to adapt to humans."Excellent Purdue study says that when fighting pandemic, we have to look at the people who are affected, and not merely the nation or the region.
"Most public health experts who are leading planning efforts for an influenza outbreak are focusing on specific geographic areas, usually counties, as defined by political lines," said George Avery, an assistant professor of health and kinesiology and member of the Purdue Alternative Care Site Planning Team. "This is problematic because if there is an outbreak, planners need to take into account the people and health-care systems that are or are not around them.
"Counties that border other states may experience nonresidents seeking treatment in their area, while other counties may be home to the only isolated hospital system in the region and can expect the population from other states to travel there for care. Health care, especially in a crisis, is not defined by county or state lines."
