Query: Spatiotemporal Dynamics, Nowcasting and Forecasting of COVID-19 in the
  United States   Epidemic modeling is an essential tool to understand the spread of the novel
coronavirus and ultimately assist in disease prevention, policymaking, and
resource allocation. In this article, we establish a state of the art interface
between classic mathematical and statistical models and propose a novel
space-time epidemic modeling framework to study the spatial-temporal pattern in
the spread of infectious disease. We propose a quasi-likelihood approach via
the penalized spline approximation and alternatively reweighted least-squares
technique to estimate the model. Furthermore, we provide a short-term and
long-term county-level prediction of the infected/death count for the U.S. by
accounting for the control measures, health service resources, and other local
features. Utilizing spatiotemporal analysis, our proposed model enhances the
dynamics of the epidemiological mechanism and dissects the spatiotemporal
structure of the spreading disease. To assess the uncertainty associated with
the prediction, we develop a projection band based on the envelope of the
bootstrap forecast paths. The performance of the proposed method is evaluated
by a simulation study. We apply the proposed method to model and forecast the
spread of COVID-19 at both county and state levels in the United States.
