The multifaceted destructions caused by COVID-19 have been compared to that of World War II. What makes the situation even more complicated is the ambiguity about the duration and ultimate spread of the pandemic. It is especially critical for the governments, healthcare systems, and economic sectors to have an estimate of the future of this disaster. By using different mathematical approaches, including the classical susceptible-infected-recovered (SIR) model and its derivatives, many… 

Impact of war on COVID-19 pandemic in Ukraine: the simulation study

Experimental studies of implementing the COVID-19 epidemic process model in Ukraine based on the polynomial regression method are described, finding that the constructed model was sufficiently accurate in deciding on anti-epidemic measures to combat the CO VID-19 pandemic in the selected area.


COVID19 outbreak presents the biggest global health creases in last century. Its pandemic spread and influence in everyday social life, economics and health is in central interest of concern for all

Analysis of COVID-19 Outbreak in Ecuador Using the Logistic Model

A simple mathematical approach is shown to understand the effect of the COVID-19 outbreak in Ecuador (and some Latin American countries such as Brazil, Peru, and Colombia), based on the exponential model, discrete logistic equation, and differential logistic model using one-year data from March 1, 2020, to February 28, 2021.

A Macroeconomic SIR Model for COVID-19

An SIR model of the COVID-19 pandemic is developed which explicitly considers herd immunity, behavior-dependent transmission rates, remote workers, and indirect externalities of lockdown, and predicts that a lockdown which ends at the arrival of herd immunity can reduce total mortality to one-third of the no-lockdown level.

A comparative study of SIR Model, Linear Regression, Logistic Function and ARIMA Model for forecasting COVID-19 cases

Starting February 2020, COVID-19 was confirmed in 11,946 people worldwide, with a mortality rate of almost 2%. A significant number of epidemic diseases including human Coronavirus display patterns.

The subject and purpose of this study is to examine the new type of coronavirus disease (COVID-19), which has turned into a global epidemic, with an economic-political approach. There are twin crises

The Multi-Compartment SI(RD) Model with Regime Switching: An Application to COVID-19 Pandemic

A variant of the SIR model for an infectious disease incorporating both the possibility of a death outcome—in a short period of time—and a regime switch that can account for the mitigation measures used to control the spreading of the infections is studied.

A Mathematical Epidemiological Model (SEQIJRDS) to Recommend Public Health Interventions Related to COVID-19 in Sri Lanka

A mathematical epidemiological model, called SEQIJRDS, having additional compartments for quarantine and infected people divided into two compartments as diagnosed and non diagnosed, compared to the SEIR model, is presented and combined public health interventions based on the projections of the proposed model are recommended.

System for Forecasting COVID-19 Cases Using Time-Series and Neural Networks Models

An “Epidemic TA” system using R programming for modeling and forecasting COVID-19 cases based on time-series models and neural network auto-regressive models (NNAR), which allows for the most accurate forecasts of infections, deaths, and vaccination cases.



Modeling and forecasting the early evolution of the Covid-19 pandemic in Brazil

Short and long term forecasts show that the social distancing policy imposed by the government is able to flatten the pattern of infection of the COVID-19 pandemic, but if this policy does not last enough time, it is only able to shift the peak of infection into the future keeping the value of the peak in almost the same value.

Extended SIR Prediction of the Epidemics Trend of COVID-19 in Italy and Compared With Hunan, China

Italy's current strict measures can efficaciously prevent the further spread of COVID-19 and should be maintained, and necessary strict public health measures should be implemented as soon as possible in other European countries with a high number of CO VID-19 cases.

Data-based analysis, modelling and forecasting of the COVID-19 outbreak

Based on the publicly available epidemiological data for Hubei, China from January 11 to February 10, 2020, estimates of the main epidemiological parameters are provided, including an estimation of the case fatality and case recovery ratios, along with their 90% confidence intervals as the outbreak evolves.

A model for COVID-19 prediction in Iran based on China parameters

The timing of the epidemic peak, hospital readiness, government measures and public readiness to reduce social contact are emphasized and the number of patients for the next month in Iran is predicted using the SIR model.

Modelling the COVID-19 epidemic and implementation of population-wide interventions in Italy

It is demonstrated that restrictive social-distancing measures will need to be combined with widespread testing and contact tracing to end the ongoing COVID-19 pandemic.

Proposed model-based strategies on how to prevent the spread of the disease in local setting, such as during social gatherings, are presented and it is shown that the exposure time is a significant factor in spreading the disease.

What Can We Estimate From Fatality and Infectious Case Data Using the Susceptible-Infected-Removed (SIR) Model? A Case Study of Covid-19 Pandemic

It is shown that the timing of the maximum and timings of the inflection points of the proportion of infected individuals can be robustly estimated from the normalized data, and the predictions were realized for all countries except USA, as long as lock-down measures were retained.
