In contrast to popular belief, the Coronavirus doesn't spread like wildfire.

It takes weeks to go from 1 to 100 cases,
A shorter time to go from 100 to 1,000 cases,
But days to go from 1,000 cases to 10,000.

This is what they were trying to teach us in logarithms.

On the extreme right, 0,1,2,3,4,5 is the rate of spread of Coronavirus.

In brackets are the number of cases.

Wave 1 has only 10 cases, but wave 5 has 100,000. The next wave has 1 million.

Logarithms basically explain the growth of a number of things in nature.

On top of that, diseases also work like conmen.

As a conman cons more people, at some point it becomes harder and harder to con new people.

As a disease infects more people, at some point it stops spreading cause it becomes harder to find new people.

But getting there only happens when very many people (more than 30 million for most countries) have been infected.

We therefore deal with deadly diseases by stopping their spread at the first few waves.

A second strategy is a vaccine, which tells your body that a certain disease is a conman.

When you vaccinate 70% or more of a population, you get what they call "herd immunity".

It reduces the chance of the rest getting it (but doesn't eliminate it)
