Background The mathematical modelling of coronavirus disease-19 (COVID-19) pandemic
has been attempted by a wide range of researchers from the very beginning of cases in …

The second wave of COVID-19, which began around 11 February 2021, has hit India very
hard with the daily cases reaching nearly triple the first peak value as on April 19, 2021. The …

COVID-19, a novel coronavirus, is currently a major worldwide threat. It has infected more
than a million people globally leading to hundred-thousands of deaths. In such grave …

We study a Gauss model (GM), a map from time to the bell-shaped Gaussian function to
model the deaths per day and country, as a simple, analytically tractable model to make …

COVID-19 epidemic is declared as the public health emergency of international concern by
the World Health Organisation in the last week of March 2020. This disease originated from …

The outbreak of coronavirus disease 2019 (COVID-19), caused by the virus severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) has already created emergency …

In this article, we analyze the growth pattern of COVID-19 pandemic in India from March 4 to
July 11 using regression analysis (exponential and polynomial), auto-regressive integrated …

Purpose To overcome the spread of the noble coronavirus, the lockdown was imposed on
March 25, 2020 by the Government of India which adversely affected the education system …

We predict the evolution of the COVID-19 pandemic in several countries using a logistic
model. The model uses a regression analysis based on the least-squares fitting. In …

We apply a versatile growth model, whose growth rate is given by a generalised beta
distribution, to describe the complex behaviour of the fatality curves of the COVID-19 …
