[Vancomycine-resistant enterocci (VRE) : a new reality in our hospitals].

Limiting the emergence and spread of multi-resistant bacteria is a global concern and the management of colonized patient represents a real challenge, especially in the hospital setting, where risks of acquisition and transmission are increased. Switzerland is not protected from undesirable trends : for instance, recent outbreaks of vancomycin-resistant enterococci (VRE) have been reported in several hospitals in western Switzerland. Since 2011, more than 250 patients have been tested positive during these outbreak episodes and the molecular analysis of the documented strains shows an unexpected diversity, including both sporadic and epidemic strains. This emerging threat requires strict monitoring, prevention and infection control strategies in our healthcare facilities.
