Modeling the Impact of Various Treatment and Prevention Tact’s on COVID-19 Worldwide

World Health Organization declared an epidemic on March 11, 2020 known as COVID-19. In the world, there are deceptive distinctions in prevalence and impermanence of COVID-19 cases in different areas. The COVID-19 first case in India was found on January 30, 2020. Presently, no remedy is available for COVID-19 treatment. The organs or the cells having ACE-2 expression are at higher risk of COVID-19, and in this manner, lymphocytes, which make a larger portion of the immune system, are the primary target of COVID-19 virus. Without authentic vaccines or treatment, there is a crucial need for the tactics of treatment and prevention for COVID-19 virus. Developing such tactics involves full understanding of how the virus is spreading in all over the world. Various treatment and prevention methods have been started worldwide such as BCG vaccination, plasma therapy, antiviral drugs, and immunoboosters to decrease the high death rate caused because of COVID-19 pandemic. Our motive is to compare various models (BHRP transmission model, SIR model, and SEIR model) and then put on different control factors to understand the results of recovery from COVID-19 virus.
