SARS-CoV-2 is recognized as a public health concern by WHO & declared it as a pandemic on 11th of March 2020. Over 4,43,03,684 people affected with the death of 11,72,955 worldwide till 28 of October 2020. The most affected country is the USA with a total no. Affected case of 90,39,170 then INDIA with a 7,99,03,222 no. of cases and death of 1,20,054 people. SARS-CoV-2 thought to commonly spread via respiratory droplets from an infected person form during talking, coughing, sneezing, etc. Several cases are found without a travel history to affected area leading to a strong possibility of community transmission. Transmission can be divided into two parts. Direct through airway droplets (respiratory droplets), through body fluid and secretions ex. Saliva, faeces, tears etc. and mother to child (ex. Breastfeeding). Indirect fomites or surfaces (objects which get infected by the patient) or objects which are uses for a checkup of an infected person. A significant number of these modes found or unfamiliar with evidence are neglected, thus is requires to specify and delineate them. Despite the fact that the writing could conceivably make reference to these courses, it is essential to underscore them as it might help in avoidance and treatment.
