A study in the Proceedings of the National Academy of Sciences has found that MRSA appears to spread from large urban hospitals to small regional hospitals by patient transmission.
For the study, researchers examined the genetic makeup of more than 80 variants of methicillin-resistant Staphylococcus aureus (MRSA) bacteria found in hospitals. The results showed that the strains that originated in the urban hospitals spread to community hospitals, likely through patient transfers.
The study concludes that measures should be taken to reduce the spread between hospitals and patients.
