Common bacteria forms on contact surfaces such as door handles, hand rails, faucet taps, table tops, your computer mouse and keyboard, and switches, spreading bacteria such as E.coli and Salmonella, and it is this bacteria that you cannot see which is causing more harm than you realize. All viruses stem from bacteria that have mutated and evolved to a state that can be highly dangerous to humans, thus creating dangerous viruses such as H1N1 and SARS.
