she did not get mrsa she got mssa, sensitive to antibiotics, working in the nhs i can tell you staphyloccoccus is the most common bug carried on human skin , membranes etc, if you are well causes no probs, but if you get a large wound, i.e from surgery then it can cause infection. Biggest carrier is from visitors and pts themselves unfortunately, obviously hand washing by staff is essential, but bacteria is all around us, the saying a bit of muck does you no harm comes to mind, most peoples immune systems are not up to date, like running a brand new computer with windows 3.1, if you congregate people who are all ill and immunocomprimised in the same building the infection will in some cases get the better, incidentally as many people die from bugs treatable with antibiotics as those that are not, we try and keep every one going but sometimes it is not possible, bacteria have been on this earth a lot longer than any of us, and they can adapt almost instantly, plus leslie ash is a slag at least getting the infection kept her off the screen
