Abstract
In the present scenario, the whole world struggling with COVID-19 which affects highly transmittable and pathogenic viral infection that rose by a newly discovered coronavirus and believed to be originated in China. The more serious effects of the virus occur for the people who are under medical problems as diabetes, chronic respiratory diseases, cancer, and cardiovascular diseases also in older persons. Because of the unavailability of proper vaccine, medical facility and medical experts the current situation becomes worst and uncontrollable for many countries. Hence, in order to overcome and reduce the spread of infection there is a necessity to prepare the predictive mathematical model due to prevention factor and suitability conditions. Enlightened by the coronavirus, the present study deals with a novel mathematical model of COVID-19 to investigate the impact of S-I-R-M model due to the influence of prevention factor and suitability conditions. Numerical calculation for infectious rate, recovery rate and mortality rate have been discussed and displayed graphically. Moreover, some comparisons have been shown in figure to estimate the effect of prevention factor.
