The virus infects a suitable host cell

The virus infects using the “key-lock principle”.
The virus receives the right key through mutations. If a virus manages to generate a new key by randomly changing its surface structure, it can infect new host cells. This means that a virus that previously only infected birds or bats can also infect humans.

How quickly do Viruses?

How does SARS-CoV-2 damage the human body?

The infected cells are destroyed and the Organ functions become restricted such as difficulty breathing, coughing, loss of smell.


The body releases messenger substances.

D

The messenger substances report the invasion of a virus to the body.

This is followed by a

Immune reaction

or

Inflammatory reaction

such as fever, weakness, etc.
