The mathematical modeling of infectious diseases is a fundamental research field for the planning of strategies to contain outbreaks The models associated with this field of study usually have exponential prior assumptions in the number of new cases, while the exploration of spatial data has been little analyzed in these models In this paper, we model the number of new cases of the Coronavirus Disease 2019 (COVID-19) as a problem of reconstruction of time-varying graph signals To this end, we proposed a new method based on the minimization of the Sobolev norm in graph signal processing Our method outperforms state-of-the-art algorithms in two COVID-19 databases provided by Johns Hopkins University In the same way, we prove the benefits of the convergence rate of the Sobolev reconstruction method by relying on the condition number of the Hessian associated with the underlying optimization problem of our method © 2020 IEEE
