Canadian data show rise in MRSA, VRE blood infections
Data collected from Canadian acute care hospitals show significant increases in methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) bloodstream infections (BSIs) in recent years, according to a study in the Canada Communicable Disease Report (CCDR).
The data, collected from 70 Canadian sentinel hospitals from 2014 through 2018 through the Canadian Nosocomial Infection Surveillance Program, show a 59.1% increase in MRSA BSIs (0.66 to 1.05 infections per 10,000 patient-days) and a 143% increase in VRE BSIs (0.14 to 0.34 infections per 10,000 patient-days).
But Clostridioides difficile infections decreased by 12.5% (from 6.16 to 5.35 infections per 10,000 patient-days). Carbapenem-resistant Enterobacteriaceae infection rates remained low and stable (0.04 infections per 10,000 patient-days), while colonization rates increased by 375% (from 0.04 to 0.19 per 10,000 patient-days).
The authors of the study said the increases in MRSA and VRE BSIs are concerning because of the increased mortality associated with these infections.
"These findings indicate a need for continued vigilance to prevent morbidity and mortality attributable to HAIs [healthcare-associated infections) and AROs [antimicrobial resistant organisms] in the inpatient population," they wrote.

European advisors recommend approval for 2-dose Ebola vaccine
European vaccine advisors today recommended the approval of Johnson & Johnson's two-dose Ebola vaccine, the European Medicines Agency (EMA) said today.
The European Commission gives final approval, but it usually follows the recommendations of its advisory committee. The vaccine, the second to be approved for Ebola, was introduced for use in the Democratic Republic of the Congo (DRC) in November 2019 as part of a clinical trial. The vaccine's two doses are given 8 weeks apart.
No new cases have been reported in the DRC's outbreak since officials reported a cluster of 7 cases recently in Beni, meaning the total stands at 3,463, the World Health Organization (WHO) said in an update yesterday. So far, no definitive source in the cluster has been found. The outbreak will be considered over if no new cases are reported before Jun 25.
