Google Algorithm to Search Out Hospital Superbugs
Googling Yourself writes "Researchers in the UK plan to use Google's PageRank algorithm to find how super-bugs like MRSA spread in a hospital setting. Previous studies have discovered how particular objects, like doctors' neckties, can harbor infection, but little is known about the network routes by which bugs spread. Mathematician Simon Shepherd plans to build a matrix describing all interactions between people and objects in a hospital ward, based on observing normal daily activity."
Triclosan is the substance that most "antibacterial" soaps contain. It has very little to do with the development of antibiotic resistance. However, several studies have shown that soap and water are about as effective with it, as without it, in terms of preventing infections.
Development of antibiotic resistance has to do with 3 factors:
1. Overprescription of antibiotics - i.e. giving Abx to someone who has a cold. Whether it's self-medication, or done by an MD is irrelevant in this case.
2. Improper prescription of antibiotics - i.e. not everything in the world can be cured with a 5-day course of Azithromycin (Zithromax). Too many doctors just hand it out like candy. We should really rely on testing for bug susceptibility in many more cases than we do now.
3. Improper use of antibiotics - i.e. not finishing the course. This is an old problem, that seems to have no solution, especially when it comes to the "internet-know-it-all" patients... who think that 5 minutes of googling qualifies them to self-medicate at will.
