Nosocomial COVID-19 in older patients has a high mortality rate. We describe an outbreak of COVID-19 in a geriatric acute care unit (GACU) in March/April 2020 and the lessons learnt regarding prevention. Thirty-six patients were diagnosed with COVID-19 during that 2-month period, in France's "first wave" of SARS-CoV-2 infections. ⋯ Attributable mortality reached 33.3% in these patients. Healthcare workers (HCW) were not spared, with an overall attack rate of 36.8%, but the rate was especially high among nurse assistants (68.2%). Repeated testing, single rooms, hand hygiene, and good use of personal protective equipment are paramount in GACUs to prevent in-hospital COVID-19 outbreaks.

Caring for patients with COVID-19 requires wearing a full set of personal protective equipment (PPE) to avoid contamination. Personal discomfort has been associated with use of PPE, and anecdotal reports describe pressure injuries related to wearing PPE. ⋯ Pressure injuries related to PPE represent an important adverse effect for nurses caring for patients with COVID-19. This topic deserves study to determine adequate solutions for preventing and treating such injuries and their potential influence on nurses' work tolerance.

Persistence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Virus and Viral RNA in Relation to Surface Type and Contamination Concentration.
The transmission of SARS-CoV-2 is likely to occur through a number of routes, including contact with contaminated surfaces. Many studies have used reverse transcription-PCR (RT-PCR) analysis to detect SARS-CoV-2 RNA on surfaces, but seldom has viable virus been detected. This paper investigates the viability over time of SARS-CoV-2 dried onto a range of materials and compares viability of the virus to RNA copies recovered and whether virus viability is concentration dependent. ⋯ However, RNA shows high stability on surfaces over extended periods. This has implications for interpretation of surface sampling results using RT-PCR to determine the possibility of viable virus from a surface, where RT-PCR is not an appropriate technique to determine viable virus. Unless sampled immediately after contamination, it is difficult to align RNA copy numbers to quantity of viable virus on a surface.
