Скачать или смотреть COVID -19 Causing Virus - How it Enters into the Human Body and What Happens After?

In this video, we are going to describe.
How COVID-19 causing virus enters the human body.
Once the virus has got access to the permissive cells, What happens next?
We know that Infected People Can Transmit COVID-19 Causing VIRUS the SARS-CoV2
There are three possible routes of human-to-human transmission (From Infected to Healthy Person)
The first mode of viral transmission is through Large drops from the mouth of an infected person to the mouth, nose, or eyes of the recipient (A Healthy Person)
In the second method Physical contact with droplets deposited on surfaces which are known as fomites also. Fomites are transferred to the recipient’s respiratory mucosae and travel to the lungs for causing infection
The third and most dangerous one is the spread of the virus mainly through the Inhalation of the microdroplets released by an infected person and held aloft by ambient air currents.
Once the healthy person has acquired the virus from the infected person what goes on next is quite intriguing
The SARS-CoV2 causing COVID-19 disease travel through the respiratory tract to the lungs and attach to cells having receptor ACE2
The COVID-19 causing virus enters into the human lungs as well as other cells through utilizing the A C E 2 receptor.
As such the first step of the virus life cycle is its Entry into the cell (Usually lungs cells) and release of the viral genome
Once the viral genomic material has been released inside the side. Some of the viral protein like viral polymerase is formed by utilizing the human ribosomal machinery. Virus just sends their genetic material inside the cells and then they hijack the cell system for their job of producing more viruses. That is the reason sometimes viruses are also called cell hijackers.
The COVID 19 disease-causing virus, like other viruses, brings its own information in the form of its genome. However, the human cell machinery is bound to obey viral information and do whatsoever the virus genetic material instruct.
Each virus instruction is first to make more viruses and infect more cells.
In earlier steps, viral polymerase protein gets translated. Human cell ribosomes do the job for the virus. Due to these reasons, Viruses are called hijackers for human cells.
For making more viruses the SARS CoV2 virus replicates its genomic material that is positive-sense strand RNA for making more viruses. An enzyme RNA Replicate is involved here. Several subgenomic RNAs are also produced that will make proteins required for SARS-CoV2 assembly.
Remember, subgenomic messenger RNAs are produced from the genomic RNA and they are used for producing various proteins virus requires for its assembly.
Now the genomic RNA of SARS-CoV2 has been produced in abundant inside the human cells. Subgenomic RNAs produce proteins required for the virus to make its assembly.
Proteins necessary for SARS CoV2 having information in subgenomic RNA are synthesized in the human cell Endoplasmic reticulum. Genomic RNA is already formed. Then comes the step in which viruses assembled inside the cell, ready to be released outside to infect other cells.
The SARS –CoV2 viruses mature inside the human Golgi vesicles. These viruses are released through the exocytosis mechanism.
For new viruses, it is easier to contact neighboring cells. Infect them and kill them, thus damaging lungs and producing more viruses.
The infected person can release these viruses through coughing, sneezing, and so on the vicious infection cycle continues.
BiomedGlobal and United Virologists Appreciate Educating People About SARS-CoV2 and other viruses. Knowledge about the viruses will empower people to adopt precautionary measures and stay safe from viral infections.
