COVID-ABS: An agent-based model of COVID-19 epidemic to simulate health and economic effects of social distancing interventions

Petrônio C.L.Silva, Paulo V.C.Batista, Hélder S. Lima et al

This interesting paper proposes the COVID-ABS, a SEIR (Susceptible-Exposed- Infected-Recovered) agent-based model that aims to simulate the pandemic dynamics using a society of agents emulating people, business and government. They identify seven different scenarios of social distancing interventions with varying epidemiological and economic effects. The seven scenarios are: (1) do nothing, (2) lockdown, (3) conditional lockdown, (4) vertical isolation, (5) partial isolation, (6) use of face masks, and (7) use of face masks together with 50% of adhesion to social isolation. They explore and discuss various scenario combinations and their respective outcomes.

Computer-aided detection of COVID-19 from X-ray images using multi-CNN and Bayesnet classifier

Bejoy Abraham, Madhu S. Nair.

Pre-trained convolutional neural networks are widely used for computer-aided detection of diseases from smaller datasets. This paper investigates the effectiveness of multi-CNN, a combination of several pre-trained CNNs, for the automated detection of COVID-19 from X-ray images. The authors use a combination of features extracted from multi-CNN with correlation-based feature selection technique and Bayesnet classifier for the prediction of COVID-19. The method was tested using two public datasets and they claimed promising results on both the datasets. This study demonstrates the effectiveness of pre-trained multi-CNN over single CNN in the detection of COVID-19.

Visualizing droplet dispersal for face shields and masks with exhalation valves

Siddhartha Verma, Manhar Dhanak, John Frankenfield

This is a rigorous scientific research on the physics of droplet spread. There is an increasing trend of public substituting surgical masks with clear plastic face shields and with masks equipped with exhalation valves. However, there is a concern that widespread public use of these alternatives to regular masks could hinder the mitigation efforts. Verma el al use qualitative visualizations to examine the performance of face shields and exhalation valves in impeding the spread of aerosol-sized droplets. The visualizations indicate that although face shields block the initial forward motion of the jet, the expelled droplets can move around the visor with relative ease and spread out over a large area disturbance. Visualizations for a mask equipped with an exhalation port indicate that a large number of droplets pass through the exhale valve unfiltered, which significantly reduces its effectiveness as a means of source control. The findings provide strong evidence to support the use of high quality cloth or surgical masks that are of a plain design, instead of face shields and masks equipped with exhale valves. View several excellent visualisation of the droplet spread with the use of various masks here.

A network-based explanation of why most COVID-19 infection curves are linear

Stefan Thurner, Peter Klimek, Rudolf Hanel

In general, the COVID-19 infection curves reveal a linear growth over extended periods. This observation is almost impossible to understand using traditional epidemiological models. One reason is that they ignore the structure of real contact networks that are essential in the dynamics of COVID-19.  Further, the authors show the effect of non-pharmaceutical interventions such as lockdowns, could be modelled with high precision. They also question the applicability of standard compartmental models to describe the COVID-19 containment phase.

Low-cost measurement of facemask efficacy for filtering expelled droplets during speech

Emma P. Fischer, Martin C. Fischer, David Grass et al.

The authors demonstrated a simple optical measurement method to evaluate the efficacy of masks to reduce the transmission of respiratory droplets during regular speech. In proof-of-principle studies, they compared a variety of commonly available mask types and observed that some mask types approach the performance of standard surgical masks, while some mask alternatives, such as bandanas, offer very little protection. This inexpensive measurement setup can be built and operated by non-experts, allowing for rapid evaluation of mask performance during speech, sneezing or coughing.

Are Runners More Prone to Become Infected with COVID-19? An Approach from the Raindrop Collisional Model

Francisco J. Arias

This paper applies physics and maths in trying to understand the behaviour of droplets produced by runners. Arias uses graphics to help the readers visualize the research problem and the methodology used. One widespread belief is that close runners, owing to the stronger exhalation, can be more prone to be infected with COVID-19 should the runner in front be infected. However, the samples are small meaning the findings cannot be generalized. Using the raindrop collisional model and computational fluid dynamics, Arias shows that the probability of collision with respiratory droplets does not always increase with the approaching velocity of the runner. Rather, there is a maximum velocity at which the efficiency of collision decreases.

A novel Monte Carlo simulation procedure for modelling COVID-19 spread over time

Gang Xie

Gang Xie develops a Monte Carlo simulation model to represent the COVID-19 spread dynamics. He performs simulations on the COVID-19 data reported for Australia and the United Kingdom. The model estimated that the number of active cases would peak around 29 March in Australia (≈ 1,700 cases) and around 22 April in the UK (≈ 22,860 cases). The results of the estimated COVID-19 reproduction numbers were consistent with the reported values. This simulation model was considered to be a useful decision making/what-if analysis tool, and for modelling any other infectious diseases that may arise.

The dispersion of spherical droplets in source–sink flows and their relevance to the COVID-19 pandemic: Physics of Fluids

C. P. Cummins, O. J. Ajayi,  F. V. Mehendale et al

This is a great physics paper. The authors investigate the dynamics of spherical droplets in the presence of a source–sink pair flow field. They use the Maxey-Riley equation to study the dynamics of the droplets. Interesting findings:  small droplets cannot go further than a specific distance. Larger droplets can travel further from the source before getting pulled into the sink. The findings that such droplets have a very short range could help scientists in the interpretation of existing data on droplet dispersion. Further research is expected to shed more light in our understanding of this very important droplet dispersion phenomenon.

The flow physics of COVID-19

Rajat Mittal, Rui Ni and Jung-Hee Seo

Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its airborne dispersion and deposition on surfaces, as well as the subsequent inhalation of these bioaerosols by unsuspecting recipients. Fluid dynamics is also key to preventative measures such as the use of face masks, hand washing, ventilation of indoor environments and even social distancing. This article summarizes what we need to learn about the science underlying these issues so that we are better prepared to tackle the next outbreak of COVID-19.

Making sense of mutation: what D614G means for the COVID-19 pandemic remains unclear

Nathan D. Grubaugh, William P. Hanage, Angela L. Rasmussen

Korber et al. (2020) found that a SARS-CoV-2 variant in the spike protein, D614G, rapidly became dominant around the world. While clinical and in vitro data suggest that D614G changes the virus phenotype, the impact of the mutation on transmission, disease, vaccine and therapeutic development are largely unknown. Here the authors try to answer questions on the potential impacts, if any, that D614G has on the COVID-19 pandemic.

SARS-CoV-2 productively infects human gut enterocytes

Mart M. Lamers, Joep Beumer, Jelte van der Vaart et al.

SARS-CoV-2 causes an influenza-like disease with a respiratory transmission route;, however, patients often present with gastrointestinal symptoms such as diarrhoea. Lamers et al. used human intestinal organoids, a “mini-gut” cultured in a dish, to demonstrate that SARS-CoV-2 readily replicates in an abundant cell type in the gut lining—the enterocyte—resulting in the production of large amounts of infective virus particles in the intestine. This work demonstrates that intestinal organoids can serve as a model to understand SARS-CoV-2 biology and infectivity in the gut.

Primary exposure to SARS-CoV-2 protects against reinfection in rhesus macaques

Wei Deng, Linlin Bao, Jiangning Liu et al.

As the COVID-19 pandemic evolves, there are still many questions we need to answer. Currently, it remains unclear whether convalescing patients have a risk of reinfection. The authors generated a rhesus macaque model of SARS-CoV-2 infection that was characterized by interstitial pneumonia and systemic viral dissemination mainly in the respiratory and gastrointestinal tracts. Rhesus macaques reinfected with the identical SARS-CoV-2 strain during the early recovery phase of the initial SARS-CoV-2 infection did not show detectable viral dissemination, clinical manifestations of viral disease, or histopathological changes. Comparing the humoral and cellular immunity between primary infection and rechallenge revealed notably enhanced neutralizing antibody and immune responses. These results suggest that primary SARS-CoV-2 exposure protects against subsequent reinfection in rhesus macaques.

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.

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.

Aerodynamic analysis of SARS-CoV-2 in two Wuhan hospitals

Yuan Liu, Zhi Ning, Ke Lan

While the transmission of SARS-CoV-2 via human respiratory droplets and direct contact is clear, the potential for aerosol transmission is poorly understood. This study investigates the aerodynamic nature of SARS-CoV-2 by measuring viral RNA in aerosols in different areas of two Wuhan hospitals during the COVID-19 outbreak in February and March 2020.  The authors propose that the virus could be transmitted via aerosols. They show that room ventilation, open space, sanitization of protective apparel, and proper use and disinfection of toilet areas can effectively limit the concentration of SARS-CoV-2 RNA in aerosols.

Temporary reduction in daily global CO2 emissions during the COVID-19 forced confinement

Corinne Le Quéré, Robert B. Jackson, Matthew W. Jones, et al

During the pandemic many international borders were closed and populations were confined to their homes, which reduced transport and changed the consumption patterns. The authors compile government policies and activity data to estimate the decrease in CO2 emissions during stay-at-home. Daily global CO2 emissions decreased by about –17% by early April 2020 compared with the mean 2019 levels. At their peak, emissions in individual countries decreased by –26% on average. They comment that government actions and economic incentives after the crisis will likely influence the global CO2 emissions.

Very little is known about the susceptibility of domestic pet animals to SARS-CoV-2. Two out of fifteen dogs from households with confirmed human cases of COVID-19 in Hong Kong SAR were found to be infected using quantitative RT–PCR, serology, sequencing the viral genome, and in one dog, virus isolation. The evidence so far suggests that these are instances of human-to-animal transmission of SARS-CoV-2. It is unclear whether infected dogs can transmit the virus to other animals or back to humans.

Temperature Decreases Spread Parameters of the New Covid-19 Case Dynamics

Jacques Demongeot , Yannis Flet-Berliac  and Hervé Seligmann

The authors collected and analysed external temperature and new covid-19 cases in 21 countries and in the French administrative regions. Associations between epidemiological parameters of the new case dynamics and temperature were examined using an ARIMA model. They demonstrated  in the first stages of the epidemic, the velocity of contagion decreases with country- or region-wise temperature. The results indicate that high temperatures diminish initial contagion rates, but seasonal temperature effects at later stages of the pandemic remain unanswered.
