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. The public reaction and health propaganda published by Governments around the world may have increased the level of public awareness, however, not enough has been done on the personal level to prevent the emergence of more viruses, or stir sufficient urgency amongst the public. The problem is that most people are oblivious to the fact bacteria and viruses are present on all surfaces especially those in public areas. Items we take for granted such as shopping trolleys, playground equipment or public tables and chairs are filled with bacteria that can potentially be lethal. Did you know that publicly used equipment is as filthy as public toilets? What about the air we breathe in daily? Biological contaminants such as bacteria, mould and mildew grow inside the dark recesses of our air conditioning, heating & duct systems. These pollutants also find their way into other microscopic areas and as a result of continually re-circulating air flow from the air-conditioning system, home owners, drivers, students, offices occupants and your business clients are repeatedly exposed to unhealthy air flow. The Sick Building Syndrome is a result of airborne pollutants and bacteria trapped and transported via the air conditioning system.
