The ability of B. cepacia complex to remain viable in chlorhexidine appears to result from a combination of efflux pump activity, biofilm formation, and cell-wall impermeability. Effective surveillance with practical monitoring by a multidisciplinary team and rapid implementation of outbreak control are even more necessary in mixed ICUs and COVID-19 ICUs. The authors suggested that national regulatory authorities establish protocols for the detection of B. cepacia complex in chlorhexidine-based products, ensuring microbiological quality of the finished product in addition to patient safety, so that similar outbreaks can be prevented."}
