Face Protection Effective In Preventing The Spread Of Influenza, Study Suggests - 0 views

  • ScienceDaily (May 22, 2009) — A new article in the journal Risk Analysis assessed various ways in which aerosol transmission of the flu, a central mode of diffusion which involves breathing droplets in the air, can be reduced. Results show that face protection is a key infection control measure for influenza and can thus affect how people should try to protect themselves from the swine flu. See also: Health & Medicine Cold and Flu Influenza Bird Flu Plants & Animals Bird Flu Research Virology Developmental Biology Reference Flu vaccine Influenza pandemic Transmission (medicine) Avian flu Lawrence M. Wein, Ph.D., and Michael P. Atkinson of Stanford University constructed a mathematical model of aerosol transmission of the flu to explore infection control measures in the home. Their model predicted that the use of face protection including N95 respirators (these fit tight around the face and are often worn by construction workers) and surgical masks (these fit looser around the face and are often worn by dental hygienists) are effective in preventing the flu. The filters in surgical masks keep out 98 percent of the virus. Also, only 30 percent of the benefits of the respirators and masks are achieved if they are used only after an infected person develops symptoms. "Our research aids in the understanding of the efficacy of infection control measures for influenza, and provides a framework about the routes of transmission," the authors conclude. This timely article has the potential to impact current efforts and recommendations to control the so-called swine flu by international, national and local governments in perspective. This study is published in the journal Risk Analysis.

Swine Flu: Influenza A (H1N1) Susceptibility Linked To Common Levels Of Arsenic Exposure - 0 views

  • ScienceDaily (May 21, 2009) — The ability to mount an immune response to influenza A (H1N1) infection is significantly compromised by a low level of arsenic exposure that commonly occurs through drinking contaminated well water, scientists at the Marine Biological Laboratory (MBL) and Dartmouth Medical School have found.

Vitamin D deficiency linked to more colds and flu: Scientific American Blog - 0 views

  •  
    Is sunshine more than just a home remedy for a cold? New research suggests it may be: In a study that will be published tomorrow, people with low levels of vitamin D - also known as the "sunshine vitamin" - were more likely to catch cold and flu than folks with adequate amounts. The effect of the vitamin was strongest in people with asthma and other lung diseases who are predisposed to respiratory infections.

Low Vitamin D Levels Linked to Colds - WebMD - 0 views

  •  
    Feb. 23, 2009 -- A walk in the sun may be better than popping a vitamin C tablet for boosting your chances of preventing the common cold or flu.\n\nA new study adds to mounting evidence that vitamin C may have been stealing the spotlight all these years from the real cold fighter, vitamin D.

CIDRAP >> Researchers find antibody that fights H5N1, seasonal flu strains - 0 views

  •  
    Feb 23, 2009 (CIDRAP News) - In a development that could create new tools to prevent and treat seasonal and pandemic influenza, researchers have identified and tested human monoclonal antibodies (mAbs) that can neutralize influenza A viruses, including lethal H5N1 avian influenza.\n\nThe findings raise hopes for a universal flu vaccine and shed light on new options for preventing and treating influenza infections, researchers from Dana-Farber Cancer Center, Burnham Institute for Medical Research, and the US Centers for Disease Control and Prevention (CDC) reported yesterday in an early online edition of Nature Structural and Molecular Biology. The study was supported by a grant from the National Institute of Allergy and Infectious Diseases (NIAID).
