A SIR model assumption for the spread of COVID-19 in different communities

Ian Cooper, Argha Mondal, Chris G.Antonopoulos

The authors present the effectiveness of the modelling approach on the pandemic and develop a susceptible-infected-removed (SIR) model that provides a theoretical framework to investigate its spread within a community.The time frame is from January to June 2020. They investigate the time evolution of different populations and monitor various parameters for the spread of the disease in various communities, including China, South Korea, India, Australia, USA, Italy and the state of Texas in the USA. They show the SIR model can help to assess the impact of the disease by offering valuable predictions on various parameters related to the spread of COVID-19 and on the number of susceptible, infected and removed populations until September 2020. Finally they conclude that the spread of COVID-19 can be under control in all communities considered, if proper restrictions and strong policies are implemented to control the infection rates early from the spread of the disease.

Current landscape of Imaging and the potential role for Artificial intelligence in the management of COVID-19

Faiq Shaikh, Michael Anderson, M. Rizwan Sohail et al.

Medical imaging plays a critical role in the early detection, clinical monitoring and outcomes assessment of COVID-19. Chest x-ray radiography (CXR) and computed tomography (CT) are the standard imaging modalities used for the structural assessment of the disease status. Artificial intelligence (AI) can enhance the predictive power and utilization of these imaging approaches and new approaches focusing on detection, stratification and prognostication are showing encouraging results. The authors review the current landscape of these imaging modalities and AI approaches as applied in COVID-19 management.

Evaluation of novel coronavirus disease (COVID-19) using quantitative lung CT and clinical data: prediction of short-term outcome.

Matos, J., Paparo, F., Mussetto, I. et al.

Volume of disease (VoD) on computed tomography (CT) scan and clinical information predict early outcome in COVID-19 patients. The authors measured VoD on CT scan of 106 COVID-19 positive patients using a simple CT post-processing tool. They found that CT and clinical data together enable accurate prediction of short-term clinical outcome.

Quantitative chest CT analysis in COVID-19 to predict the need for oxygenation support and intubation

Ezio Lanza, Riccardo Muglia, Isabella Bolengo et al.

The authors performed a single-centre retrospective study on COVID-19 patients hospitalised from January 25, 2020, to April 28, 2020, who received CT at admission prompted by respiratory symptoms such as dyspnea or desaturation. The authors tested quantitative CT analysis (QCT) as an outcome predictor for COVID-19. They found that may serve as a tool for the triaging process of COVID-19.

Household secondary attack rate of COVID-19 and associated determinants in Guangzhou, China: a retrospective cohort study

Qin-Long Jing, Ming-Jin Liu, Zhou-Bin Zhang et al.

The authors estimated the secondary attack rate of SARS-CoV-2 among household and non-household close contacts in Guangzhou, China, using a statistical transmission model. They found that SARS-CoV2 is more transmissible in households than SARS-CoV and Middle East respiratory syndrome coronavirus. Older individuals (aged ≥60 years) are the most susceptible to household transmission of SARS-CoV-2.

Digital Health Strategies to Fight COVID-19 Worldwide: Challenges, Recommendations, and a Call for Papers

Guy Fagherazzi, Catherine Goetzinger, Mohammed Ally Rashid et al

In this editorial, the authors discuss the current situation regarding digital health solutions to fight COVID-19 as well as the challenges and ethical issues. Telemedicine has been established as a successful health care model. Social media platforms such as Twitter and Google Trends analyses are very beneficial to model pandemic trends as well as to monitor the evolution of patients’ symptoms or public reaction to the pandemic over time. Digital tools can provide collective public health benefits but individual freedoms may be compromised. There is a strong potential for various digital health solutions and many more to be explored.  We need to ensure the future digital health initiatives will have a greater impact on the epidemic and meet the most strategic needs to bring about relief to sufferings.

Potent neutralizing antibodies from COVID-19 patients define multiple targets of vulnerability

Philip J. M. Brouwer, Tom G. Caniels, Karlijn van der Straten et al.

The authors describe their work in isolating monoclonal antibodies from three convalescent COVID-19 patients using a SARS-CoV-2 stabilized prefusion spike protein. They found that a subset of the antibodies were able to potently inhibit authentic SARS-CoV-2 infection as low as 0.007 μg/mL. In addition to providing guidance for vaccine design, the antibodies described here are promising candidates for COVID-19 treatment and prevention.

Andrew Clark, Mark Jit, Charlotte Warren-Gash et al.

The authors estimated the number of individuals at increased risk of severe COVID-19 and to see how this varies between countries to inform the design of possible strategies to shield or vaccinate those at highest risk.  They found that about one in five individuals worldwide could be at increased risk of severe COVID-19, should they become infected, due to underlying health conditions, but this risk varies considerably by age.

Identifying airborne transmission as the dominant route for the spread of COVID-19

Renyi Zhang, Yixin Li, Annie L. Zhang, et al

The authors describe the transmission pathways of COVID-19 by analyzing the trend and mitigation measures in three epicentres. They show that the airborne transmission route is highly virulent and dominant for the spread of COVID-19. Their analysis shows that the difference with and without mandated face covering represents the determinant in shaping the trends of the pandemic. This protective measure significantly reduces the number of infections. They also show that measures such as social distancing alone implemented in the United States are insufficient in protecting the public.

The COVID‐19 Pandemic — Can open access modeling give us better answers more quickly?

Mary Beth Allen  Michael Mills  Mehdi Mirsaeidi

In this editorial, the authors introduce ‘System dynamics as the process of representing a complex system with interrelated parts that interact in a nonlinear and unpredictable method within a system and predicting those interactions and outcomes’. They then review several models that had been used during the pandemic, however  most of models have focused specifically on the epidemiology of disease. They argue for an open access model to serve as an important resource as new data continues to emerge and social distancing policies relax across the world.  They encourage the medical physics community to take advantage of systems dynamics as a useful tool for research.

Tackling COVID-19 pandemic through nanocoatings: Confront and exactitude

Pradeep Kumar Rai,  Zeba Usmani. Vijay Kumar Thakur,  et al

The authors review the research and possible protection and care possibilities against COVID19. COVID19. Previous research findings suggest the usage of nanotechnology as an important avenue to develop antiviral drugs and materials to effectively minimize the acquired infection of COVID-19 in public places like hospitals, transport, schools, worship places, malls, etc. Antimicrobial nanocoatings at these places and development of targeted antiviral drugs through capped nanoparticles could likely be a major effective option to halt the spread of this disease.
