After the spread of this infectious disease started to the whole world the transmission and mortality started rising slowly.
In January the World Health Organisation (WHO) announced this as an international concern and later when the cases were increased exponentially in march it was declared as a pandemic. After this, the medical teams of the whole world respond to it and start analyzing its pattern of host-virus interaction. What are its genomic sequence and a lot more. To help the world the information data starts flowing from one nation to another. Now, this disease becomes a major global issue for the human world. In the early days, the symptoms of this infectious disease were divided into two symptomatic and asymptomatic. The patient has the symptoms like high fever, cough, sneezing, loss of taste, loss of smell are symptomatic patients and if they were not cured on time then this disease will become pneumonia and later death due to organ failure.

This virus infects the respiratory tracts of the human-like Nose, throat, lungs, etc, and later causes shortening of breath. In the early days, there was no specific detection kit was there and no specific medicine to cure this disease. So at that stage the techniques which are used for the detection are:
Now there are Various antigen-antibody based detection kit is available which gives the report in minutes. They are fast easily applicable technique and easy to handle one
