The Message………..
Thanks to media hype about H1N1, several people who trust me have either approached or called me to advice. The hype in media about the utility of face masks and N95 respirators as a tool for general protection against H1N1 can’t be deplored enough. Yesterday, a friend who listened wanted me to write down briefly what I advised so that he could tell others in similar words. Hence this short email to friends whom I have advised recently (and others whom I haven’t yet). Please realize that this is not an official advice, especially the one about face masks or N95.
Most N95 respirators are designed to filter 95% particulates of 0.3µ, while the size of H1N1 virus is about 0.1µ. Hence, dependence on N95 to protect against H1N1 is like protecting against rain with an umbrella made of mosquito net.
