As a child my daughter acquired two infections when she had an operation on her leg. A three day stay turned into a month long ordeal. Now days this would be called a HAI, Hospital-Acquired infection. Today this is a major problem. The CDC estimates that 1.7 million people will get HAIs and 99,000 people die each year.
One day while I was sitting in the hospital Hospital with my daughter I moved the chair. Underneath the chair was dust that looked like it had been there a year. Obviously cleanliness was a problem. In Hospitals the cleaning staff is not necessarily given enough time to clean the rooms thoroughly. Research shows that more than half of the surfaces remain untouched.after cleaning.
There are many micro organism that are HAIs the most dangerous are Clostridium difficile (C. diff), MRSA, Carbapenem-Resistant Enterobacteriaceae (CRE) and Acinetobacter baumannii. Some superbugs such as C. diff are showing resistance to disinfectants, making them even harder to eliminate. Others, like CRE, have developed a resistance to antibiotics, making them nearly impossible to treat. CRE is expected to become more dangerous than MRSA.
Xenex Healthcare Services LLC has developed a robot that disinfect hospital rooms by using Ultraviolet light. When the ultraviolet light hits a bacteria and viruses it breaks their DNA into pieces. Ultraviolet rays do the same in humans causing skin cancer.The Robot takes 5 to 10 minutes to clean a room.It can clean any room in the hospital. It has been shown to be 20 times more effective than chemical cleaning. In one hospital they reduced C. diff infections by 53%.
