How corona virus destroy human immune system

 


How corona virus destroy human immune system: One drop of saliva contains almost 200000 corona virus particles. Corona virus does not have floating ability but it can combine with dust particles and in that way it can float for hours. It is estimated this virus has the ability to retain on the glass surface for 96 hours, on plastic and steel surface it retains for about 72 hours, and on cardboard 24 hours.

Mostly corona virus attack on lungs because the lung cells have H2 receptors and corona virus has spike on its surface. In simple words if the Hreceptor of lung cell is lock then spike protein or spike  of corona virus is key. That’s why it infect mostly lungs cell as cells of other body organs does not possess H2 receptors.

Our cell membrane is selectively permeable which means only selective or beneficial particles (nutrients etc) can pass through it, but spikes of corona virus cheat security system of membrane and enter into the cell where it start creating millions of its copies by process of replication.

Because of osmotic pressure the cell ruptures and replicated virus infect other healthy cells

The time span of corona virus, entry in human body and rupturing of the cell is called incubation period which is 10 days that is why corona virus spread rapidly.
