When we kill germs with powerful disinfectants, we eliminate the chances of allowing our immune system to strengthen itself. I see commercials for cleaners that kiil 99.9% of bacteria, commercials for disinfectants aimed at parents using children as an excuse for sanitizing everything they touch so they don't get a cold.
The more we continue to push for stricter standards, and the increased sanitization of our homes, workplaces, and restaurants, the weaker our immune systems will get, and the more deadly previously harmless germs will become.
GERMS ARE GOOD!
All I can say is "I told you so.".
I agree with your premise - people aren't dirty enough these days, and it's bad for them. However, this is a virus, not a "germ". Disinfectants like the ones you describe do not work against viruses, and will neither help nor hinder the spread of the swine flu virus.
I've noticed several design suggestions in your code.
