Background: In The Netherlands the MRSA 'Search and Destroy' policy is applied nationally. It is based on screening of patients considered at risk for carriage of MRSA. The objective of this study was to determine the incidence and sources of MRSA found in patients and health care workers (HCW) in the Amphia hospital over the years 2002 until 2007. Methods: Data of the Infection Control Department were used to retrieve all MRSA positive patients and HCW found during the years 2002 until 2007. The MRSA source was based on a risk factor questionnaire and strain typing. The sources were categorised as ‘related to foreign hospital’, ‘animal-related’, ‘nosocomial transmission’, ‘transmission in other Dutch care institute’, ‘transmission in the community’ and ‘source unknown’. Results: During 2002 until 2007, 144 persons with MRSA were found, i.e. 121 in patients and 23 in HCW. Twenty-two percent was related to a foreign hospital, 28% to animals, 17% was due to nosocomial transmission, 3% to transmission in another Dutch health care institute, 10% to transmission in the community and in 19% the source was unknown. The annual incidences and sources of MRSA are shown in figure 1. Conclusion: The incidence of MRSA over the years 2006 and 2007 increased more than 300% compared to previous years. This increase was caused by the introduction of MRSA related to pig and calf farmers and to an increase with an unknown source.
