Infection
Immunity
Starvation
Stampede
Infection - The Virus or Bacteria Destroys your cells
Immunity - The Virus or Bacteria does not directly destroy the cells. But the Immune reaction to the virus or bacteria destroys the cells
To Understand this, see this picture
This is the classic example of
Stampede : breakdown of law and order
What does Lock Down does
It reduces Death due to 1 and 2
It increased death due to 3 and 4
(4 initially comes down briefly, but once hunger sets is 4 increases)
Assume You lock down your country immediately
What will happen
There will be less death due to 1 and 2
but
If you are locking down very late
The deaths due to 1 and 2 will be very high, but due to 3 and 4 will be less
So
There is a right time
A right time
Where lockdown saves maximum lives from 1 and 2
loses minimum lives to 3 and 4
May vary from
Country to Country
State to State
District to District
City to City
Area to Area
Closing down or School and Colleges is easiest as the economic impacts of that are less
But
In everything else, The adverse effects also need to be considered
Over Crowding --> More Spread
This defeats the very purpose
So
order of Lockdown also is important
Trains, Buses
Metro
Which Order
That is important
Essentially Hotels will operate "underground" (like alcohol sales during prohibilition)
Hotels supplying food through backdoor for higher cost
may increase infection as well as starvation as well as stampede
Lots of Data and ground knowledge is required to decide
We do not have all these data or knowledge
Govt has
If they decide to announce something
it means
They take decision based on data which we don't have
So
It is best to support them
instead of giving advices :)
