Wearing masks and establishing COVID-19 areas reduces secondary attack risk in nursing homes

AbstractBackgroundCOVID-19 is spreading rapidly in nursing homes (NHs). It is urgent to evaluate the effect of infection prevention and control (IPC) measures to reduce COVID spreading.MethodsWe analysed COVID-19 outbreaks in 12 NH using rRT-PCR for SARS-CoV-2. We estimated secondary attack risks (SARs) and identified cofactors associated with the proportion of infected residents.ResultsThe SAR was below 5%, suggesting a high efficiency of IPC measures. Mask-wearing or establishment of COVID-19 zones for infected residents were associated with lower SAR.ConclusionsWearing masks and isolating potentially infected residents appear to limit SARS-CoV-2 spread in nursing homes.

In relation to the challenging epidemic situation in Russia caused by the spread of novel coronavirus infection, specialists from the Russian NBC Protection Troops were involved in the disinfection of different facilities and equipment in all regions of the country. The aim of this article was to summarize the experience of mobile Decontamination Operational Groups (DOGs) of the NBC Protection Troops in infection prevention and control for COVID-19 in Moscow and Moscow Region. The mobile DOGs for this region were formed on the basis of the Federal State Budgetary Establishment «27 Scientific Centre» of the Ministry of Defence of the Russian Federation. This center possessed vast experience in performing special tasks for ensuring radiation, chemical and biological safety of different objects. The DOGs were formed from highly qualified professionals with relevant experience in scientific research studies in radiation, chemical and biological protection issues. During the period March 30 to June 28, 2020, the mobile DOGs have performed cleaning and disinfection procedures for different objects at more than 120 addresses in Moscow City and Moscow Region. Thus, they have decontaminated 550 thousand sq. m of surfaces, 13491 units of automotive equipment, 67 passenger cars for personnel, 18 IL-76 aircrafts of the Russian Aerospace Forces and supportive machinery. Nevertheless, the experience of DOGs in infection prevention and control for COVID-19 in Moscow and Moscow Region demonstrated the need to improve the NBC protections means and disinfectant solutions. In general, the disinfection measures organized and carried out by the mobile DOGs have demonstrated high efficiency. There have not been a single case of COVID-19 among DOGs personnel throughout the entire period of performing cleaning and disinfection tasks in epidemic foci

Background/Objectives: To identify which infection prevention and control (IPC) precautions in long-term care facilities (LTCF) were associated with reduced COVID-19 incidence and mortality among residents and reduced COVID-19 incidence in health care professionals (HCP). Design: Retrospective data on self-assessment of adherence to 101 IPC measures collected via an online questionnaire sent to 825 nursing homes in France in December 2020. Setting and participants: Medical and administrative staff jointly reported data on IPC measures, characteristics of LTCF, counts of residents’ COVID-19 deaths and cases, and counts of HCP cases. Measurements: Random forest models were used to identify the most important IPC measures associated with reduced number of COVID-19 deaths and cases in residents and cases in HCP. The identified variables were then included in linear regression models to estimate the association between levels of adherence to each selected IPC measure and COVID-19 deaths and cases. No data on time of IPC measures implementation were collected. Results: Data from 307 LTCF (37.2%) were collected, accounting for 22,214 residents. A higher number of COVID-19 deaths in residents was associated with a better adherence to physical distancing in group activity rooms. A better adherence by HCP to physical distancing during their mealtimes and break times was associated with fewer COVID-19 cases among residents and HCP. Other IPC measures were not significantly associated with COVID-19 cases or deaths. Conclusion: Physical distancing between residents was more implemented when LTCF had been confronted with COVID-19 deaths. Physical distancing between HCP was associated with fewer COVID-19 cases in residents and HCP, suggesting it may prevent significantly COVID-19 spreading in LTCF. HCP should particularly adhere to physical distancing measures during their mealtimes and break times. A higher adherence to such preventive measures does not require extra material or human resources and may be easily achievable.
