TLDR
Wang et al. as mentioned in this paper proposed a new deterministic SEIR(R)D-SD model by introducing the re-infection rate and social distancing factor into the traditional SEIRD (Susceptible, Exposed, Infectious, Recovered (Re-infected) and Deceased-based Social Distancing model).About:

An incremental learning approach to prediction models of SEIRD variables in the context of the COVID-19 pandemic
TL;DR: In this article , the authors proposed an approach based on incremental learning to build predictive models of the SEIRD variables for the COVID-19 pandemic, which is a dynamic ensemble method that allows the addition of new models or the updating of incremental models.

State Estimation of the Spread of COVID-19 in Saudi Arabia using Extended Kalman Filter
TL;DR: In this paper , the authors considered the nonlinear compartmental epidemiological dynamical system model in the Susceptible-Exposed-Infected-Quarantined-Recovered-Deceased (SEIQRD) form based on the recursive estimator known as the extended Kalman filter (EKF) to predict the evolution of the COVID-19 pandemic in Saudi Arabia.
Journal ArticleDOI
Recursive state and parameter estimation of COVID-19 circulating variants dynamics
TL;DR: In this article , a SEIR-based model is proposed considering dynamic feedback estimation, which is suitable for dynamic feedback as simulation results presented an efficient detection and dynamic characterization of circulating variants.

An improved epidemiological-unscented Kalman filter (hybrid SEIHCRDV-UKF) model for the prediction of COVID-19. Application on real-time data
TL;DR: In this article , an extension/improvement of the classic SIR compartmental model is proposed, which also takes into consideration the populations of exposed, hospitalized, admitted in intensive care units (ICU), deceased and vaccinated cases, in combination with an unscented Kalman filter (UKF), providing a dynamic estimation of the time dependent system's parameters.

Interval type-2 Fuzzy control and stochastic modeling of COVID-19 spread based on vaccination and social distancing rates
TL;DR: In this article , an interval type-2 fuzzy stochastic modeling and control strategy was proposed to deal with the realistic uncertainties of pandemics and manage the size of the infected population.

TL;DR: A SARS-CoV-2 variant carrying the Spike protein amino acid change D614G has become the most prevalent form in the global pandemic, and it is found that the G614 variant grows to higher titer as pseudotyped virions.

TL;DR: The role of asymptomatic SARS-CoV-2 infected individuals in disseminating the infection remains to be defined and the conventional wisdom based on overall immunity of the infected patients cannot explain this broad spectrum in disease presentation.
