Daily pandemic surveillance, often achieved through the estimation of the reproduction number, constitutes a critical challenge for national health authorities to design counter-measures. In an earlier work, we proposed to formulate the estimation of the reproduction number as an optimization problem, combining data-model fidelity and space-time regularity constraints, solved by nonsmooth convex proximal minimizations. Though promising, that first formulation significantly lacks robustness…

A New Framework and Software to Estimate Time-Varying Reproduction Numbers During Epidemics
This tool produces novel, statistically robust analytical estimates of R that incorporates uncertainty in the distribution of the serial interval and should help epidemiologists quantify temporal changes in the transmission intensity of future epidemics by using surveillance data.
Spatial and temporal regularization to estimate COVID-19 Reproduction Number R(t): Promoting piecewise smoothness via convex optimization
A new estimation procedure for the evolution of the reproduction number is proposed here, assuming a well-accepted model for current incidence data, based on past observa- tions.
Automated data-driven selection of the hyperparameters for Total-Variation based texture segmentation
The theoretical asymptotic unbiasedness of the gradient estimator is demonstrated in the case of general correlated Gaussian noise and the proposed parameter selection strategy is particularized to fractal texture segmentation, where problem formulation naturally entails inter-scale and spatially correlated noise.

Evidence of this spread is provided and modelling efforts undertaken to understand and forecast SARS-CoV-2 are documents, including a short section about the new variants that emerged in late 2020.

Epidemiological characteristics of COVID-19 cases in Italy and estimates of the reproductive numbers one month into the epidemic
The COVID-19 infection in Italy emerged with a clustering onset similar to the one described in Wuhan, China and likewise showed worse outcomes in older males with comorbidities, supporting the importance of combined non-pharmacological control measures.
Epidemiological parameters of coronavirus disease 2019: a pooled analysis of publicly reported individual data of 1155 cases from seven countries
Background The outbreak of coronavirus disease 2019 (COVID-19) has been declared a pandemic by the World Health Organization, while several key epidemiological parameters of the disease remain to be
Estimating the burden of SARS-CoV-2 in France
France has been heavily affected by the SARS-CoV-2 epidemic and went into lockdown on the 17th March 2020, and population immunity appears insufficient to avoid a second wave if all control measures are released at the end of the lockdown.
Expected impact of lockdown in Île-de-France and possible exit strategies
A stochastic age-structured transmission model integrates data on age profile and social contacts in the Île-de-France region to assess the current epidemic situation, evaluate the expected impact of the lockdown implemented in France on March 17, 2020, and estimate the effectiveness of possible exit strategies.
Sparsest Continuous Piecewise-Linear Representation of Data
We study the problem of interpolating one-dimensional data with total variation regularization on the second derivative, which is known to promote piecewise-linear solutions with few knots. In a
