| Summary: | Mathematical and epidemiological simulation plays a pivotal role in predicting, anticipating, and controlling present and future epidemics. To better understand and model the dynamics of a specific infection, researchers need to consider the influence of many variables ranging from micro-host–pathogen interactions to host-to-host encounters, and the prevailing cultural, social, economic, and local customs worldwide. As reported by the WHO, a novel corona virus (COVID-19) is identified as the etiological virus through Wuhan pneumonia for unknown etiology with Chinese administration on Jan 7, 2020. This virus is designated as an unsympathetic SARS-Cov-2 by International Commission for Taxonomy of Viruses on Feb 11, 2020. The main aim is to enlarge a phase based mathematical modelling to specify the transferability of this disease. It is developed Reservoir-individuals spreading set of connections modelling for imitating the prospective broadcast as of the infectivity foundation in the direction of the person infectivity. In view of the fact that, the Reservoir has set of connections to rigid to see the sights obviously as well as communal anxieties are concentrating on top of the spreading starting reservoir to individuals. The subsequent generation matrix methodology is endorsed towards compute the fundamental reproduction number (R0) through the RP modelling to measure the transferability by the COVID-19. The values of R0 are estimated from reservoir to human being as well as starting individual to individual, that is to say, the accepted quantity of less important diseases this consequence from presenting a solitary contaminated personality addicted to differently susceptible inhabitants. The present model demonstrated that the spreading of COVID-19 is superior to the Middle-East pulmonary infirmity during the Middle-East nationals, analogous to harsh sensitive pulmonary infirmity, but inferior than Middle-East pulmonary infirmity within the Republic of Korea. It can also extend this study to some other countries, including Saudi Arabia, Italy, and Germany etc. The COVID-19 pandemic has become the leading societal concern. The pandemic has shown that the public health concern is not only a medical problem, but also affects society as a whole; so, it has also become the leading scientific concern.
