MRSA is mainly spread by patients moving between hospitals, Dutch researchers have said.The authors have called for more screening of people who are repeatedly admitted to different hospitals to try to break this transmission cycle. They said this would eventually help to eradicate MRSA. The conclusions were drawn from a large study of the geographical location of different strains of MRSA across 26 European countries. MRSA is a potentially lethal bug which is difficult to combat because it has developed resistance to some antibiotics. The study was published in the journal, PloS Medicine.
