Virus, what are you ??

The pandemic of Covid has highlighted the existence of viruses, yes we all know the word virus but what is a virus and how can we protect ourselves against this threat?

What is a virus ???

A virus by the definition of the dictionary is :

virus noun [C] (DISEASE) extremely small piece of organic material that cause disease in humans, animals, and plants.

So basically a piece of organic material that makes you ill.
The scientific community says that at any given moment there are billions of virus on earth.

But before a virus enters its host cell it is called a virion. An entire virus particle.

All viruses contain 3 components

Nucleic Acid – Just as in cells, the nucleic acid of each virus encodes the genetic information for the synthesis of all proteins. While the double-stranded DNA is responsible for this in prokaryotic and eukaryotic cells, only a few groups of viruses use DNA. Most viruses maintain all their genetic information with the single-stranded RNA. There are two types of RNA-based viruses. In most, the genomic RNA is termed a plus-strand because it acts as messenger RNA for direct synthesis (translation) of viral protein. A few, however, have negative strands of RNA. In these cases, the virion has an enzyme, called RNA-dependent RNA polymerase (transcriptase), which must first catalyze the production of complementary messenger RNA from the virion genomic RNA before viral protein synthesis can occur.

Capsid – The capsid is the protein shell that encloses the nucleic acid; with its enclosed nucleic acid, it is called the nucleocapsid. This shell is composed of protein organised in subunits known as capsomers. They are closely associated with the nucleic acid and reflect its configuration, either a rod-shaped helix or a polygon-shaped sphere. The capsid has three functions: 1) it protects the nucleic acid from digestion by enzymes, 2) contains special sites on its surface that allow the virion to attach to a host cell, and 3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic acid into the cell’s cytoplasm. Under the right conditions, viral RNA in a liquid suspension of protein molecules will self-assemble a capsid to become a functional and infectious virus.

Envelope – Many types of viruses have a glycoprotein envelope surrounding the nucleocapsid. The envelope is composed of two lipid layers interspersed with protein molecules (lipoprotein bilayer) and may contain material from the membrane of a host cell as well as that of viral origin. The virus obtains the lipid molecules from the cell membrane during the viral budding process. However, the virus replaces the proteins in the cell membrane with its proteins, creating a hybrid structure of cell-derived lipids and virus-derived proteins. Many viruses also develop spikes made of glycoprotein on their envelopes that help them to attach to specific cell surfaces.

So now we know what a virus is what is the point of a virus?

This is a simple question to answer, just like the rest of the living world a virus exists to replicate and stay alive….. BUT……the virus replicates in the host cell and then bursts out this process is called lysis, which kills the host cell and this in turn will eventually kill the host. This  way virus are always ion the lookout for a new host to repeat the process and stay alive


How do we get a virus?

It is quite simple Viruses spread from person to person mainly in droplets that fly out when you cough or sneeze. Viruses are also passed along when you touch mucus droplets from someone else on a surface like a desk and then touch your own eyes, mouth, or nose before you get a chance to wash your hands. Viruses like the flu can live 24 hours or longer on plastic and metal surfaces like cafeteria tables, doorknobs, and cups.

So I know what your thinking I just don’t touch my face ……Well it turns out that in a 16 hour day (not including 8 hrs sleep) we would touch our face 256 times and unless you sanitise/wash your hands before each time you touch your face you are at risk.

So what’s the solution to keeping safe ??

Here at Touch Zone Clean, we offer a virus barrier protection that can help protect you from those accidental touches of the face and transmission of viruses, for 30 days. We use specially designed cleaning solutions to provide ongoing protection and we use the very best application methods
