Impact of COVID-19 pandemic waves on health-care worker hand hygiene activity in department of medicine and ICU as measured by an automated monitoring system.

Background: Hand hygiene (HH) compliance among health-care workers is important for preventing transmission of infectious diseases.

Aim: To describe health-care worker hand hygiene activity in ICU and non-ICU patients' rooms, using an automated monitoring system (AMS), before and after the onset of the COVID-19 pandemic.

Methods: At the Intercommunal Hospital of Créteil, near Paris, France, alcohol-based hand sanitizer (ABHS) consumption in the Department of Medicine (DM) and ICU was recorded using an AMS during four periods: before, during, and after the first wave of the COVID-19 pandemic, and during its second wave.

Household transmission and incidence of positive SARS-CoV-2 RT-PCR in symptomatic healthcare workers, clinical course and outcome: a French hospital experience.

Objectives: Although healthcare workers (HCWs) have been particularly affected by SARS-CoV-2, detailed data remain scarce. In this study, we investigated infection rates, clinical characteristics, occupational exposure and household transmission among all symptomatic HCWs screened by SARS-CoV-2 RT-PCR between 17 March (French lockdown) and 20 April.

Methods: SARS-CoV-2 RT-PCR was proposed to symptomatic (new cough or dyspnoea) HCWs at Creteil Hospital in one of the Parisian suburbs most severely affected by COVID-19.
