Mathematical model-based analysis has proven its potential as a critical tool in the battle
against COVID-19 by enabling better understanding of the disease transmission dynamics …

In this paper, we conduct mathematical and numerical analyses for COVID-19. To predict the
trend of COVID-19, we propose a time-dependent SIR model that tracks the transmission …

The outbreak of novel coronavirus-caused pneumonia (COVID-19) in Wuhan has attracted
worldwide attention. Here, we propose a generalized SEIR model to analyze this epidemic …

After the spread of the SARS-CoV-2 epidemic out of China, evolution in the pandemic
worldwide shows dramatic differences among countries. In Europe, the situation of Italy first …

In this paper, we propose a dynamical model to describe the transmission of COVID-19,
which is spreading in China and many other countries. To avoid a larger outbreak in the …

Background: Mathematical modeling of vector-borne diseases and forecasting of epidemics
outbreak are global challenges and big point of concern worldwide. The outbreaks depend …

Abstract World Health Organization (WHO) has declared COVID-19 a pandemic on March
11, 2020. As of May 23, 2020, according to WHO, there are 213 countries, areas or territories …

In this study, a novel reaction–diffusion model for the spread of the new coronavirus (COVID-
19) is investigated. The model is a spatial extension of the recent COVID-19 SEIR model …

The coronavirus pandemic has rapidly evolved into an unprecedented crisis. The
susceptible-infectious-removed (SIR) model and its variants have been used for modeling …

Over the past few months, the spread of the current COVID-19 epidemic has caused
tremendous damage worldwide, and unstable many countries economically. Detailed …
