Hospital Acquired Infection may be a Thing of Past

Posted by Prahallad Panda on 9:14 PM Comments

Around 100,000 people in North America die every year from hospital acquired infections or nosocomial infection. That means 100,000 people every year are dying from potentially preventable infections.
It is also a fact that the microbes in hospital are becoming resistant to common antibiotics and are persisting in spite of use of best available disinfectants; recent example is bacteria having NDM 1 gene (New Delhi Metalloproteinase 1). This is a global phenomenon.
An infectious disease expert from Queen's University has developed a disinfection system that may be very good in freeing the hospital rooms, beds and equipments from microbes.

Medizone International at laboratories Innovation Park, Queen's University is commercializing the technology and the first batch is expected in the first quarter of 2012.

The new technology involves pumping a Medizone-specific ozone and hydrogen peroxide vapor gas mixture into a room; and it is far more effective in killing bacteria than wiping down a room.
The entire disinfection process is faster than other methods and it takes less than one hour.
Ozone is used as disinfectant for water in some places. Body defense produces ozone and hydrogen peroxide in order to kill the invaders. That is the source of inspiration for the scientists.
This technology can also be used in food preparation and processing areas; and to disinfect cruise ships after an infection outbreak.
