The Masks Could Be Doing More Harm Than Good

You may have seen pictures of people wearing surgical masks in areas where there have been severe cases of the so called "swine flu" -- but -- our deputy chief medical health officer - Dr Paul Van Buynder - says people using masks when they don't need to can actually infect the masks and transmit the virus when normally they may not have.Van Buynder says public health strongly believes people ill with the flu should not go to work and should stay home in isolation to help prevent the spread of the virus.
