Chlorhexidine daily bathing: impact on health care-associated infections caused by gram-negative bacteria.
Health care-associated infections (HAIs) are a major cause of morbidity and mortality in intensive care unit (ICU) patients. Our objective was to evaluate the impact of daily bathing with chlorhexidine gluconate (CHG) on the incidence rates of HAIs, with a focus on their causative bacteria, in a French ICU. ⋯ CHG daily cleansing reduced the incidence rate of HAI caused by gram-negative bacteria, highlighting the role of the transient gram-negative bacteria skin colonization in the pathogenesis of HAI.

Comparative StudySurveillance versus clinical adjudication: differences persist with new ventilator-associated event definition.
The National Healthcare Safety Network (NHSN) has recently supported efforts to shift surveillance away from ventilator-associated pneumonia to ventilator-associated events (VAEs) to decrease subjectivity in surveillance and minimize concerns over clinical correlation. The goals of this study were to compare the results of an automated surveillance strategy using the new VAE definition with a prospectively performed clinical application of the definition. ⋯ There was good agreement between the study teams. Awareness of the limitations of the surveillance definition for VAE can help infection prevention personnel in discussions with critical care partners about optimal use of these data.

To our knowledge, no studies to date demonstrate potential spread of microbes during actual emergency medical service (EMS) activities. Our study introduces a novel approach to identification of contributors to EMS environment contamination and development of infection control strategies, using a bacteriophage surrogate for pathogenic organisms. ⋯ Results suggest firefighters' hands were the main vehicles of microbial transfer. Current practices were not consistently applied or standardized and minimally reduced prevalence and quantity of microbial contamination on EMS surfaces. Although use of a consistent protocol of H2O2 wipes significantly reduced percent prevalence and concentration of viruses, training and promotion of surface disinfection should be provided.

Increased reports of measles in a low endemic region during a rubella outbreak in adult populations.
In 2013, a rubella outbreak was observed in Japan, Romania, and Poland. The outbreak in Japan was accompanied by an increase of measles reports, especially from a region where measles is highly controlled. This was attributed to the adult populations affected by this rubella outbreak, similarity of clinical signs between rubella and measles, sufficiently small impact of measles outbreaks from neighboring nations, and elimination levels of measles endemicity. Current and future concerns for measles control are discussed.
