Perspective on the basic reproduction number in controlling the corona-virus disease transmission: A models based study

Abstract

COVID-19 is an
egressing infectious disease caused by a
novel coronavirus (SARS-CoV-2),
recently erupted from the
Wuhan city of China.Then this contagious pneumonia like virally driven disease started to spread in almost all continent.
After declaration from WHO that coronavirus disease is pandemic in nature, many researchers in different branches such as medical sciences as well as mathematical sciences have show their immense concern to develop the strategies to control this disease transmission. For this purpose I have used basic reproduction number as a controlling parameterto check this disease. I have employed different type of methods such as next generation matrix (NGM) to calculatethe basic reproduction number from some epidemic scenarios using SIR, SEIR models. We have consider the quarantine as well as isolation mechanism for coronavirus disease transmission. We have studied the basic reproduction numbers and concluded that quarantine and isolation is the fundamental criterion to control this disease transmission. It is also concluded that respective administration has to enforce strictly the lockdown $\&$ restrictive stratigies of human movement from one place to another along with they have to ensure other supportive masures to establish the socio-economic balance during this pandemic circumstances.
