This study demonstrates that an adoption of a segmenting and shielding strategy could increase the scope to partially exit COVID-19 lockdown while limiting the risk of an overwhelming second wave of infection. We illustrate this using a mathematical model that segments the vulnerable population and their closest contacts, the ‘shielders’. Effects of extending the duration of lockdown and faster or slower transition to post-lockdown conditions and, most importantly, the trade-off between…

Comparison of COVID-19 outcomes among shielded and non-shielded populations

Shielding has not been effective at preventing deaths in those with highest risk from COVID-19, and to be effective as a population strategy, shielding criteria would need to be widely expanded to include other criteria, such as the elderly.

Critical weaknesses in shielding strategies for COVID-19

It is demonstrated that shielding the vulnerable while allowing infections to spread among the wider population would not have been a viable public health strategy for COVID-19 and is unlikely to be effective for future pandemics.

Exit strategies from lockdowns due to COVID-19: a scoping review

Among the different exit strategies reviewed (phase-wise exit, hard exit, and constant cyclic patterns of lockdown), phase-wiseexit appears to be the optimal exit strategy.

How to overcome lockdown: selective isolation versus contact tracing

It is argued that there is a possible alternative: a mandatory, centralised contact-tracing app that is ethically preferable to the selective isolation of the elderly, because it does not target members of a certain group, relying instead on the movements of each individual, and because it avoids the extended isolation of certain members of the society.

Mathematical modeling of COVID-19 transmission dynamics in Uganda: Implications of complacency and early easing of lockdown

A phased-out lifting of lockdown measures, minimization of COVID-19 transmissibility within hospital settings, elimination of recruitment of infected individuals as well as enhanced contact tracing would be key to preventing overwhelming of the healthcare system that would come with dire consequences.

Emerging from lockdown – what went wrong ?

As many Western countries emerged from initial periods of lockdown in spring 2020, they had brought COVID-19 infection rates down significantly. This was followed, however, with more drastic second

An Optimization Framework to Study the Balance Between Expected Fatalities Due to COVID-19 and the Reopening of U.S. Communities

A computationally fast optimization framework is presented to study the delicate balance between reopening U.S. communities and controlling severe cases of COVID-19 that lead to hospitalizations and fatalities, and demonstrates a practical approach to conduct decision-making in an uncertain environment.

Draft paper , 21 December 2020 Living with a Pandemic : How to Do Better than Lockdown

The COVID-19 pandemic presents us with the question of how healthcare systems can be prevented from being overwhelmed while avoiding general lockdowns. We focus on two strategies that show promise in

Impact of visitation and cohorting policies to shield residents from covid-19 spread in care homes: an agent-based model

Key questions for modelling COVID-19 exit strategies

A roadmap to facilitate the development of reliable models to guide exit strategies is proposed, and has three parts: improve estimation of key epidemiological parameters; understand sources of heterogeneity in populations; and focus on requirements for data collection, particularly in low-to-middle-income countries.



Evaluation of "stratify and shield" as a policy option for ending the COVID-19 lockdown in the UK

This work examines the performance required from a classifier that uses information from medical records to assign risk status for a such a stratify-and-shield policy to be effective in limiting mortality when social distancing is relaxed and shows that at least 80% of those who would die if unshielded would be allocated to the high-risk shielded group comprising 15% of the population.

Mathematical modelling of COVID-19 transmission and mitigation strategies in the population of Ontario, Canada

Dynamic physical distancing could maintain health-system capacity and also allow periodic psychological and economic respite for populations and could reduce the median number of cases in ICU below current estimates of Ontario’s ICU capacity.

Quantifying the impact of physical distance measures on the transmission of COVID-19 in the UK

The physical distancing measures adopted by the UK public have substantially reduced contact levels and will likely lead to a substantial impact and a decline in cases in the coming weeks, but this projected decline in incidence will not occur immediately.

Intervention Serology and Interaction Substitution: Modeling the Role of ‘Shield Immunity’ in Reducing COVID-19 Epidemic Spread

An epidemiological intervention model that leverages serological tests to identify and deploy recovered individuals as focal points for sustaining safer interactions via interaction substitution is developed and analyzed, showing that a shield immunity approach may significantly reduce the length and reduce the overall burden of an outbreak.

Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period

Using existing data to build a deterministic model of multiyear interactions between existing coronaviruses, with a focus on the United States, is used to project the potential epidemic dynamics and pressures on critical care capacity over the next 5 years and projected that recurrent wintertime outbreaks of SARS-CoV-2 will probably occur after the initial, most severe pandemic wave.

Social network-based distancing strategies to flatten the COVID-19 curve in a post-lockdown world

Fusing models from epidemiology and network science, Block et al. show how to ease lockdown and slow infection spread by strategic modification of contact through seeking similarity, strengthening communities and repeating interaction in bubbles.
