Covid-19 crisis Hypothesis - the virus reduce in severity over time
I want to make an observation and to put up a hypothesis. 

When the covid virus first appeared in Wuhan, China, it was lethal. Many people died. It affected mostly the elderly people, but many young people also succumb to the virus.

It move to Italy and cause large fatalities. It then spread to other cities in Europe and America, with devastating results. 

A few months later, the virus became less lethal. The death rate came down. 

When happened? Here is my hypothesis. I suspect that the virus becomes less harmful over time. 

What could have happened is that the virus remains in the body and spread to another person. The body of the infected person produces antibodies that fight the virus. This weakened the virus. 

When it spreads to another person, it becomes weaker than the original virus. In some cases, the virus may still be strong, but generally, over the course of time, it becomes weaker. 

When a new variant of the virus appears, it becomes lethal again. After a few months, that variant becomes weaker again.

This is my speculation, as I do not have any knowledge of the virus and how it harms people.

Even if my hypothesis is true, I do not know how we can use this knowledge to fight the virus. 

Maybe, we have to accept the "fact" that the virus will rampage for a few months and then become less of a threat.
