This point-prevalence study was conducted to establish rates of meticillin-resistant Staphylococcus aureus (MRSA) nasal carriage in GPs in three counties in the West of Ireland. One hundred and twenty GPs were randomly selected for the study and 78 participated. The prevalence rate of nasal carriage of MRSA in these participants was 7.7%. A number of GPs in the West of Ireland have nasal carriage of MRSA. The results emphasise the need for high standards of infection control in primary care.
