    A fourth-grade student in Olympia, Washington has won her local science fair by demonstrating that hand sanitizers suck at killing E. coli.

    Nine-year-old Celia Vernon won her class science fair at Roosevelt Elementary with an experiment involving a live sample of E. coli. Under the guidance of her father, a biologist with a background in microbiology, Vernon tested several solutions on E.coli, including Purell brand hand sanitizer.

    In a side-by-side comparison with common bleach, the E.coli on the Purell side survived. On the bleach side, it died.

    The Vernons say they have no bone to pick with Purell, but were surprised to learn it doesn't kill one of the main dangers associated with exposures from using bathrooms.

    A spokesperson for the makers of Purell told KING 5 News that it stands by its claims to kill 99 percent of germs and suggested we contact the Centers for Disease Control and Prevention. A CDC spokesperson says they have not studied hand sanitizers specifically on E.coli and recommend hand sanitizers only when soap and water are not available.

    I know 99 per cent sounds cool, but considering the volume of bacteria out there, it don’t mean squat.

    New Zealand researchers report in Eurosurveillance today about hand sanitiser use in a hospital entrance foyer four months after a baseline study during New Zealand’s influenza pandemic.

    Of the 743 people observed over one (summer) day in December 2009, 8.2% used the hand sanitiser, which was significantly lower (p<0.0001) than the 18.0% reported in the August (winter) study. Health authorities may need to intensify promotion of hand hygiene to reduce the impact of future influenza pandemic waves.

    We’re exploring more on the shock and shame approach in a number of settings.

    Megan Hardigree, a research associate at Kansas State University working on hand hygiene, writes that this year, Cinco de Mayo wasn’t just a holiday to celebrate the Mexican army’s victory over the French in the Battle of Puebla (yesterday) or a song by the band, Cake. It was also a day to celebrate the launch of the World Health Organization’s (WHO) newest hand hygiene campaign: Save Lives: Clean Your Hands.

    The aim of Save Lives: Clean Your Hands is to stop the spread of infection by increasing hand hygiene of healthcare workers. This is said to be the next step of the original, Clean Care is Safer Care, from 2005. The initiative persuades individuals to join the movement with gain-framed messages (they apparently encourage positive behavior) such as “Help stop hospital acquired infections in your country” and “Make patient safety your number one priority.”

    To help support this initiative, WHO has accompanied the promotion with a variety of tools and resources to aid healthcare facilities in promoting and enforcing better hand hygiene. These tools include: tools for system change, tools for training and education, tools for evaluation and feedback, tools as reminders in the workplace, and tools for institutional safety climate. My personal favorite, mostly because of the fun diagram, is in the “tools as reminders in the workplace” which includes “My 5 Moments for Hand Hygiene:”

    • before touching a patient;
    • before clean/aseptic procedures;
    • after body fluid exposure/risk;
    • after touching a patient; and,
    • after touching patient surroundings.

     “Be a part of a global movement to improve hand hygiene, “ says WHO.

    Now to evaluate whether any of these messages actually compel people to wash their hands.
