I am not sure if this is a right question, but I do not intend to hurt anybody’s sentiments. We assume there are 10 people of different ethnic origins. All 10 belong to the same social class, and they are at one place but at different locations and none of them meet each other or come in contact with each other. They breathe the same air, consume the same food, use similar personal utilities and so on. All of them have the same behaviour pattern (social, personal etc.). It is impractical to assume this but let us keep that way. None of the 10 people belong to this place that is, their origin has nothing to do where they are currently now. They have been left or may be abandoned at that place. So, in brief, we assume that they are in the same surroundings. They do not have any health problems; they have the same blood group and blood parameters are same. They have the same breathing rate and have same weight and height.
Now we assume that the place is severely affected by Covid. And all of them are equally indisciplined. Will all of them get affected equally?
