Compare the expected bird flu pandemic with that of protection of computer systems and you will see that relying on any magic pill for protection is a naive response.
Hell if computer systems used this approach for protection today we wouldn’t have enough technology left to run a remote control.
Viruses of both types change continually - in fact the only likelihood of widespread computer virus is through a new or modified virus. Breeding a successful computer pandemic relies on bypassing the existing technology i.e. the virus changes to circumvent the current protection.
The answer is to plan for a mutated or new virus that existing protection will not cure.
Detection and isolation response not existing vaccines are now the critical factors to buy time to build defenses for an outbreak.
After evidencing the bureaucracies between governments and agencies even in the case of the recent isolated hurricane, I doubt that there is even a worldwide phone list to advise of an influenza outbreak.
It will be too late to wait for the first plane load of virus ridden tourists to arrive.
News at 7 - oops we goofed again.
