Methicillin-resistant Staphylococcus aureus, or MRSA, is a bacteria found in hospitals, that is resistant to antibiotics.
The Swedish Institute for Infectious Disease Control says that of the 1,057 cases of MRSA recorded in Sweden last year, 155 were contracted by people in hospitals, and 361 were infected in the wider community. A further 439 people contracted MRSA abroad, with the majority of cases also coming from outside hospitals.
It was not known from where a further 102 cases originated.
According to the paper, the average age of those contracting the bug is also falling. Previously, MRSA was most common amongst the elderly in care and in hospitals.
