ABSTRACT
We assessed the impact of COVID-19 on healthcare workers (HCWs) from data on 2.9 million cases reported from nine countries in the EU/EEA. Compared to non-HCWs, HCWs had a higher adjusted risk of hospitalization (IRR 3.0 [95% CI 2.2-4.0]), but not death (IRR 0.9, 95% CI 0.4-2.0). Article Summary LineHealthcare workers are hospitalized more frequently than non-healthcare workers when adjusting for age, sex, and comorbidities.
ABSTRACT
Soft surfaces in the health-care setting harbor potentially pathogenic bacteria and fungi that can be transferred to patients and personnel. We evaluated the in vitro antimicrobial efficacy of two types of innovative copper-coated textiles against a variety of nosocomial multi-drug resistant (MDR) pathogens. Five isolates each of MDR Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii and Enterococcus faecium as well as three Candida parapsilosis were tested. The antimicrobial activity of copper-coated para-aramide and copper-coated polyester swatches was compared to that of non-copper coated controls using a quantitative method. Reduction of viable colonies by >3log10 from starting inoculum was characterized as bactericidal activity. No viable colonies of S. aureus, P. aeruginosa, E. faecium and C. parapsilosis were recovered after the first hour of contact while for A. baumannii, no viable colonies were recovered after only 15min of contact with either type of copper-coated textiles. Copper-coated para-aramide exhibited a bactericidal effect at 15min of contact with A. baumannii, at 1h with S. aureus, P. aeruginosa, E. faecium and C. parapsilosis and at 3h with K. pneumoniae. Copper-coated polyester was bactericidal at 15min of contact for A. baumannii and at 1h for the other species tested. Both copper-coated textiles exhibited a rapid and significant antimicrobial effect. Antimicrobial textiles may have a role in the arsenal of strategies aiming to reduce environmental contamination in the health-care setting.
