So what do we do in the hospital
If the covid19 attacks lungs the patient can't breathe
We give them oxygen in face mask if attack is less
If attack is more
We put them on ventilator
We need to give dialysis to the patient
So
Treatment depends on how good or bad the lung is or liver is or kidney is
The test result has NO role in treatment of the individual
Treatment depends on how each organ in the patient functions
We can know how many people are affected and whether rate of spread is more or less with time
For that it is enough to test a certain number of people
That is what we are now doing
For example blood sugar test
We measure blood sugar and modify insulin or tablet dose as per that
So
They have mistaken that treatment depends on the test
They are worried that unless they have a test result positive
They won't be treated
They are not ready to understand
They simply
Look at that, look at this
Instead of looking at basic science and logic
