Serial interval of novel coronavirus (COVID-19) infections.
Reads0
Chats0
TLDR
The serial interval of COVID-19 is close to or shorter than its median incubation period, indicating that a substantial proportion of secondary transmission may occur prior to illness onset and that calculations made using the SARS serial interval may introduce bias.Citations

Risk and the Republican National Convention: Application of the Novel COVID-19 Operational Risk Assessment.
David W Callaway,Jeff Runge,Lucia Mullen,Lisa Rentz,Kevin Staley,Michael Stanford,Crystal Watson +6 more
TL;DR: In this paper, the authors present a risk assessment and mitigation tool for decision-makers to assess SARS-CoV-2 transmission risks that may arise as organizations and businesses hold mass gatherings or increase business operations.
Journal ArticleDOI
Sensitivity analysis of the infection transmissibility in the UK during the COVID-19 pandemic
TL;DR: In this paper, sensitivity analysis of transmissibility of the infection as the effects of removing restrictions, for example by returning different occupational groups to their normal working environment and its effect on the reproduction number in the UK was performed.

Cell-Based Platform for Antigen Testing and Its Application for SARS-CoV-2 Infection
Marvin A. Ssemadaali,Sherri Newmyer,Harikrishnan Radhakrishnan,Juan Arredondo,Harold S. Javitz,Satya Dandekar,Parijat Bhatnagar +6 more
TL;DR: The DxCell platform is a cell-based self-replicative antigen test that detects molecular signatures of the target pathogen and can be distributed in small quantities to testing facilities for expansion on site to the desired volume and introduces an opportunity for a decentralized testing network.

Modelling the evolution of COVID-19 in high-incidence European countries and regions: estimated number of infections and impact of past and future intervention measures
TL;DR: A previously developed mechanistic model of COVID-19 transmission has been adapted and applied here to study the evolution of the disease and the effect of intervention measures in some European countries and territories where the disease had major impact.

On the parametrization of epidemiologic models -- lessons from modelling COVID-19 epidemic
TL;DR: In this paper, a principled approach to parametrize SIR-type epidemiologic models of different complexities by embedding the model structure as a hidden layer into a general Input-Output Non-Linear Dynamical System (IO-NLDS) is presented.

TL;DR: There is evidence that human-to-human transmission has occurred among close contacts since the middle of December 2019 and considerable efforts to reduce transmission will be required to control outbreaks if similar dynamics apply elsewhere.

TL;DR: It is estimated that a single infectious case of SARS will infect about three secondary cases in a population that has not yet instituted control measures, and public-health efforts to reduce transmission are expected to have a substantial impact on reducing the size of the epidemic.

TL;DR: The incubation period falls within the range of 2–14 days with 95% confidence and has a mean of around 5 days when approximated using the best-fit lognormal distribution and it is recommended that the length of quarantine should be at least 14 days.
Journal ArticleDOI
Factors that make an infectious disease outbreak controllable.
TL;DR: It is concluded that severe acute respiratory syndrome and smallpox are easier to control using these simple public health measures and should be a priority during an outbreak of a novel infectious agent.
