Let us find the answer
And
In the process let us understand the significance of Lock down, social distancing once again
There is a fort and the fort has 100 soldiers
Now
What happens when an enemy comes and attacks this forte
The 100 soldiers in the forte will kill them in no time
And
After killing them, they will seize the enemies weapons, their maps, their attacking methods and be prepared for next attack
Let us consider this as scenario 1
The 100 soldiers in the forte will be killed by the 1000 soldiers of the enemy and the forte will fall down
Let us consider this as Scenario 2
Let us consider this as Scenario 3
Now
The strengths are equal. so there will be a seige around the forte. The enemy cannot enter in, but at the same time, the enemy has not be chased away. This is scenario 4
They were able to barely kill the Soldiers in the fort and enter the fort. But Another 100 soldiers are guarding the palace and now the seige is at the level of palace instead of forte wall. This is Scenario 5
If the incoming viral load is very low, the body's immunity will kill them off
This is scenario 1
This is scenario 2
Assume you have a vaccine for this virus. That is Scenario 3 (you must have guessed this by now)
Assume that the body's defence is waging a valiant battle and holding the virus at the throat and the patient is not showing any symptoms
this is Scenario 4 and this is probably happening right now
Even others can refresh it
But
At the same time, the virus is not able to enter the lungs to cause pneumonia
This is Scenario 5 described above
What happens when 100 more enemy soldiers come into Scenario 4 --> It changes to Scenario 5
This is very very important
When you are having the virus in the throat
When your immune system is fighting it
But still not able to throw it off
If you add more virus ?
Now
What happens when 100 more soldiers come to Scenario 5 ie Forte wall has fallen, Palace has not fallen . . The palace also will fall and become scenario 6
When you have Sore Throat, if you go and meet more people and get more virus, you will land up with pneumonia
In other words
Scenario 4 + 100 Enemy Soldiers = Scenario 5
Scenario 5 + 100 Enemy Soldiers = Scenario 6
Scenario 4 + 200 Enemy Soldiers = Scenario 6
If you are having sore throat , if you meet 10 people and if one of you give a viral load, you get pneumonia
That is
More People you meet with Virus
The more severe disease you have
This is why we need Social Distance, Isolation, Quarantine
When the hundred soldiers are fighting against enemy in the fort wall, if your friendly helicopter comes and kills the enemy soldiers, you win
That helicopter is brushing and mouth wash
Stay at Home
Stay Indoors
Meet Less People
Have maximum distance between people
Keep the meeting time minimum
Follow Government Rules
Trust Government
Don't follow Rumours
All the best
