Abstract. In this paper, we attempt to describe the spread of COVID-19 based on an
extensions of the well-known SEIR models. We bring in a new representation to appraise
and manage the spread of infectious disease COVID-19 through SEIHR pandemic model,
which is based on the supposition that the infected individuals are isolated and the necessary
treatments are arranged so that they cannot taint the other residents in the community.
Dynamics of the SEIHR model is presented by basic reproduction number R
0
and the
comprehensive stability analysis. The reproduction number was also determined for the
epidemiological model and found to be consistent with the local stability condition for the
disease-free equilibrium. We establish the positivity and boundedness of solutions, local and
global stability analysis of equilibria to examine its epidemiological relevance. To validate
the model and estimating the important model parameters and prediction about the disease,
we consider the real cases of Ethiopia from 4th March to 20th August 2020.
1. Introduction
In December 2019, corona virus first reported in Wuhan, China, is an infectious disease
caused by a newly discovered corona virus. The virus is now known as the severe acute
respiratory syndrome corona virus 2 (SARS-CoV-2). The disease it causes is called corona
virus disease 2019 (COVID-19) [1]. According to WHO Novel Corona virus disease situa-
tion report 21 January 2020, the first case outside of China was reported in Thailand on
13 January 2020, Japan on 15 January 2020 and Republic of Korea on 20 January 2020
[2]. Currently the COVID-19 outbreak has now spread over the world. According to WHO
the symptoms of COVID-19 may appear two to 14 days after exposure. This time after
exposure and before having symptoms is called the incubation period i.e., during this period
the infected humans are not infectious. However, the patients infected by COVID-19 will
have symptoms including fever, cough and difficulty breathing, and the severe patients may
have renal failure. This list is not all inclusive [3]. Current evidence suggests that COVID-19
