EARSS activities and results: update.

(And with EARSS participants) The latest EARSS results (1990-2000) suggest that the rates of methicillin resistant S. aureus and Penicillin Non Susceptible S. pneumoniae are higher in southern European countries than in the North. Young children, followed by elderly people are the most at risk for an infection by PNSP. The risk to be infected by methicillin resistant S. aureus increases with age, patients hospitalised in intensive care units being more exposed to that risk.
