[Epidemiologic evidence on the role of hospitality venues in the transmission of COVID-19: A rapid review of the literature]. / Evidencia epidemiológica acerca del rol de la hostelería en la transmisión de la COVID-19: una revisión rápida de la literatura.

OBJECTIVE: To review the scientific epidemiologic evidence on the role of hospitality venues in the incidence or mortality from COVID-19. METHOD: We included studies conducted in any population, describing either the impact of the closure or reopening of hospitality venues, or exposure to these venues, on the incidence or mortality from COVID-19. We used a snowball sampling approach with backward and forward citation search along with co-citations. RESULTS: We found 20 articles examining the role of hospitality venues in the epidemiology of COVID-19. Modeling studies showed that interventions reducing social contacts in indoor venues can reduce COVID-19 transmission. Studies using statistical models showed similar results, including that the closure of hospitality venues is amongst the most effective measures in reducing incidence or mortality. Case studies highlighted the role of hospitality venues in generating super-spreading events, along with the importance of airflow and ventilation inside these venues. CONCLUSIONS: We found consistent results across studies showing that the closure of hospitality venues is amongst the most effective measures to reduce the impact of COVID-19. We also found support for measures limiting capacity and improving ventilation to consider during the re-opening of these venues.

Selective perimeter lockdowns in Madrid: a way to bend the COVID-19 curve?

Lockdowns have been widespread used to limit social interaction and bend the epidemic curve. However, their intensity and geographical delimitation have been variable across different countries. Madrid (Spain) implemented perimeter lockdowns in September with the purpose of bending the COVID-19 curve. In this article, we compared, using join point regressions, the evolution of COVID-19 cases in those areas where this intervention was implemented and those where it was not. According to our analysis, the decrease in the epidemic curve started before the impact of the perimeter lockdown could be reflected.

[Efficiency is not enough. Ethical analysis and recommendations for the allocation of scarce resources in a pandemic situation]. / La eficiencia no basta. Análisis ético y recomendaciones para la distribución de recursos escasos en situación de pandemia.

OBJECTIVE: To develop a support tool to decision-making in the framework of the COVID-19 pandemic. METHOD: Different ethical recommendations that emerged in Spain on prioritizing scarce health resources in the COVID-19 pandemic first wave were searched; it was conducted a narrative review of theoretical models on distribution in pandemics to define an ethical foundation. Finally, recommendations are drawn to be applied in different healthcare settings. RESULTS: Three principles are identified; strict equality, equity and efficiency, which are substantiated in specific distribution criteria. CONCLUSIONS: A model for the distribution of scarce health resources in a pandemic situation is proposed, starting with a decision-making procedure and adapting the distribution criteria to different healthcare scenarios: primary care settings, nursing homes and hospitals.
