The case fatality ratio (CFR) for COVID-19 is difficult to estimate. One difficulty is due to ignoring or overestimating time delay between reporting and death. We claim that all of these cause large errors and artificial time dependence of the CFR. We find that for each country, there is a unique value of the time lag between reported cases and deaths versus time, that yields the optimal correlation between them is a specific sense. We find that the resulting corrected CFR (deaths shifted back… Expand

Interpretation of COVID-19 case fatality risk measures in England
CFR is an informative indicator of crude mortality risk, however, it should be presented separately by age and sex, and interpreted carefully within the specific context of testing practices and healthcare provision, using England as an example. Expand
Physics-informed machine learning for the COVID-19 pandemic: Adherence to social distancing and short-term predictions for eight countries
This work links directly, through machine learning techniques, infection data at a country level to a single number that signifies social distancing effectiveness, and extracts the degree of linear dependence in social distanced that led to the specific infections. Expand
Analysis of Hospital Resource Availability and COVID-19 Mortality Across the United States.
While the impact of coronavirus disease 2019 (COVID-19) has varied greatly across the United States, there has been little assessment of hospital resources and mortality. We examine hospitalExpand
Association of State Stay-at-Home Orders and State-Level African American Population With COVID-19 Case Rates
Results from multivariate regression models indicated that stay-at-home orders were associated with reductions in cumulative COVID-19 case rates and the need to address racial disparities in rates of infection. Expand
A scaling approach to estimate the age-dependent COVID-19 infection fatality ratio from incomplete data
The ‘universal’ increase of the mortality rate with age observed in different countries since the beginning of their respective outbreaks is exploited, combined with the results of the antibody prevalence tests in the population of Spain, to unveil both unknowns. Expand


Potential Biases in Estimating Absolute and Relative Case-Fatality Risks during Outbreaks
Two forms of bias that may affect the estimation of the overall case-fatality risk—preferential ascertainment of severe cases and bias from reporting delays—are described and solutions that have been proposed and implemented in past epidemics are reviewed. Expand
Estimating the infection horizon of COVID-19 in eight countries with a data-driven approach
This work uses the quantitative landscape of the disease spreading in China as a benchmark and utilizes infection data from eight countries to estimate the complete evolution of the infection in each of these countries, based on a Gaussian spreading hypothesis. Expand
Real-time monitoring the transmission potential of COVID-19 in Singapore, March 2020
The trajectory of the reproduction number in Singapore underscores the significant effects of successful containment efforts in Singapore, but it also suggests the need to sustain social distancing and active case finding efforts to stomp out all active chains of transmission. Expand
Estimating the infection and case fatality ratio for coronavirus disease (COVID-19) using age-adjusted data from the outbreak on the Diamond Princess cruise ship, February 2020

Adjusting for delay from confirmation to death, case and infection fatality ratios (CFR, IFR) for coronavirus disease (COVID-19) on the Diamond Princess ship as 2.6% and 1.3% (95% confidence interval: 0.89–6.7) are estimated, respectively. Expand
Case-Fatality Rate and Characteristics of Patients Dying in Relation to COVID-19 in Italy.
Since then, the number of cases identified in Italy has rapidly increased, mainly in northern Italy, but all regions of the country have reported having patients with COVID-19, and Italy now has the second largest number of CO VID-19 cases and also has a very high case-fatality rate. Expand

Findings support ongoing efforts to flatten-the-curve, which likely reduces the probability of hospitals being overrun and therefore delivering suboptimal care. Expand
COVID-19 antibody seroprevalence in Santa Clara County, California
The estimated prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that COVID-19 was likely more widespread than indicated by the number of cases in late March, 2020; at the time, low-burden contexts such asSanta Clara County were far from herd-immunity thresholds. Expand
First-wave COVID-19 transmissibility and severity in China outside Hubei after control measures, and second-wave scenario planning: a modelling impact assessment
The first wave of COVID-19 outside of Hubei has abated because of aggressive non-pharmaceutical interventions, but given the substantial risk of viral reintroduction, close monitoring is needed to inform strategies against a potential second wave to achieve an optimal balance between health and economic protection.
