Here is ABC AM stuff:<\/p>\n<p><em>Australians are rushing to buy surgical masks as fears of a swine flu pandemic grow.<br \/>\nBut one occupational health specialist says people are wasting their money because most common surgical masks will not protect you from the disease.<br \/>\nCharlie Lahoud runs Sydney&#8217;s International Airport pharmacy and says business started picking up when swine flu hit the headlines on Monday.<br \/>\n&#8220;[They are] extremely popular. One of the first requests we get is &#8216;do you have face masks?&#8217;,&#8221; he said.<br \/>\n&#8220;I think that they&#8217;re just scared, they just want to ensure they get protected whilst travelling overseas, and, if anyone around them has got the virus, that they don&#8217;t come in contact with it through that form, I guess.<br \/>\n&#8220;I&#8217;d say sales jumped up by at least 30 to 40 per cent on the Monday, followed closely by Tuesday, when we sold out, and we had to put in a quick order of six boxes for Wednesday.&#8221;<br \/>\nHe says it is predominantly people leaving the country wanting the masks, although there have been some requests from arrivals.<br \/>\nAmcal is Mr Lahoud&#8217;s supplier of surgical masks and it would not comment on its sales.<br \/>\nBut <strong>Dr David Bromwich,<\/strong> who is an adjunct associate professor at Griffith University, specialises in population health and says some masks are next to useless at protecting you from disease.<br \/>\n&#8220;It&#8217;s a very common thing that people think that if they see a doctor wearing a mask, or it becomes a cultural thing of wearing a mask, that it actually gives them protection,&#8221; he said.<br \/>\n&#8220;But very often it will just protect other people, and not the wearer.<br \/>\n&#8220;I&#8217;ve even seen pictures of people wearing industrial masks with exhaust valves who are suspected of getting swine flu, contracting it, and that gives no protection to other people.<br \/>\n&#8220;So we&#8217;re getting a lot of confusion with the selection of respiratory protection.&#8221;<br \/>\nHey says people wanting to protect themselves should be looking for two types of masks.<br \/>\n&#8220;One with a P2 marking on &#8211; that&#8217;s the Australian certification &#8211; and the other with an N95 marking on it, with the United States certification,&#8221; he said.<br \/>\n&#8220;The problem is, even if you do get those, then the fit of the mask is important &#8211; particularly around the nose. If you don&#8217;t have a good fit, then air will flow through these microscopic gaps.&#8221;<br \/>\nDr Bromwich says the mask must be completely sealed, as even stubble around the face could let in germs.<br \/>\nBut he says masks that fit well could substantially reduce your risk of getting the flu.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I was called by the ABC National Radio program &#8220;AM&#8221; at 6:30 this morning to be interviewed about the use of face masks for protection against swine flu.
