Evolution of the incidence of COVID-19 during the first five waves in residents and professionals of nursing homes in Normandy, France.

Background: Older adults living in nursing homes (NH) paid a heavy price to the COVID-19 pandemic, despite early and often drastic prevention measures.

Aims: To study the characteristics and the impact of the pandemic on NH residents and professionals over 2 years.

Methods: Cross-sectional study of COVID-19 clusters among residents and/or professionals in NH, from March 2020 to February 2022, in Normandy, France.

Professional practice for COVID-19 risk reduction among health care workers: A cross-sectional study with matched case-control comparison.

Background: Health care workers (HCWs) are particularly exposed to COVID-19 and therefore it is important to study preventive measures in this population.

Aim: To investigate socio-demographic factors and professional practice associated with the risk of COVID-19 among HCWs in health establishments in Normandy, France.

Methods: A cross-sectional and 3 case-control studies using bootstrap methods were conducted in order to explore the possible risk factors that lead to SARS-CoV2 transmission within HCWs.

Healthcare associated coronavirus disease 2019 among health care workers in Normandy, France: a multi-center study.

Introduction: In the early phase of the coronavirus disease (COVID-19) epidemic in France, knowledge of SARS-COV-2 characteristics was limited, and personal protective equipment (PPE) was lacking. Thus, health care workers (HCWs) were exposed to nosocomial transmission.

Methods: A multicenter regional descriptive study of fifty-two heath care facilities covering 30,533 HCWs in western Normandy, France, from March 3 to March 27, 2020, before the incidence threshold of 10/100,000 inhabitants was crossed in the study area.

Investigation of Serratia marcescens surgical site infection outbreak associated with peroperative ultrasonography probe.

Early postoperative infections due to Serratia marcescens have been reported by both clinicians and microbiologists in our teaching hospital. Here, we present an interlinked clinical, epidemiological, environmental and genomic investigation of this outbreak due to a T-shaped intraoperative probe contaminated by S. marcescens used during peroperative ultrasonography in laparoscopic liver resection.

Effectiveness of an intervention campaign on influenza vaccination of professionals in nursing homes: A cluster-randomized controlled trial.

Background: Seasonal influenza has a major individual and collective impact, especially among the elderly living in nursing homes. To prevent infection by influenza viruses, vaccination of residents and professionals is an essential measure. However, while the vaccination rates of residents are generally high (>85%), rates among professionals are generally approximately 20%.
