What Is Coronavirus (COVID-19)
The virus in question was a coronavirus that caused the 2003 pandemic of severe acute respiratory syndrome, or SARS.
Coronaviruses are a group of viruses covered in small protein spikes that resemble a crown—or “corona” in Latin.
There are hundreds of known Coronaviruses. Seven of them infect humans, and can cause disease.
How was Coronavirus (COVID-19) Discovered?
For nearly a decade, scientists chased the source of a deadly new virus through China’s highest mountains and most isolated caves. He finally found it here: among the bats of Shitou Cave.
Cause of Coronavirus And Infected Organs.
The coronavirus SARS-CoV causes SARS, MERS-CoV causes MERS, and SARS-CoV-2 causes the disease COVID-19.
Four of the seven human coronaviruses cause colds, mild, highly contagious infections of the nose and throat.
Two infect the lungs, and cause much more serious illness. The seventh, which causes COVID-19, spreads easily but can severely affect the lungs.
Corona Infected Person And How Corona Spreads.
When an infected person coughs, droplets containing the virus are expelled. When droplets enter the nose or mouth.
So the virus can infect a new person. The coronavirus communicates best in enclosed spaces, where people are close to each other.
Efforts To Stop The Growing Coronavirus.
Keep a distance of 2 yards from one person to another new person and use a mask. Use sanitizer whenever you come from outside.
Cold weather keeps their delicate covering from drying out, allowing the virus to survive longer between hosts, while UV exposure from sunlight can damage it.
These seasonal changes matter more for established viruses.
But since no one is yet immune to the new virus, it has so many potential hosts that it doesn’t need ideal conditions to spread.
Effects Of Coronavirus On The Body.
In the body, protein spikes embed the host’s cells and fuse with-
Enables the virus to hijack the host cell’s machinery to replicate its own genes.
RNA viruses or DNA viruses store their genes. All viruses are either RNA viruses or DNA viruses.
About the characteristic and identity of the coronavirus.
To combat this risk, coronaviruses have a unique feature: an enzyme that checks for replication errors and corrects mistakes.
This makes coronaviruses more stable, with a slower mutation rate than other RNA viruses.
While this may sound terrifying, the slow mutation rate is actually a promising sign when it comes to disarming them. after an infection,
Our immune system can recognize microbes and if they infect us again destroy them more quickly so they don’t make us sick.
But mutations can make a virus less recognizable to our immune systems—and therefore more difficult to fight.
They can also make antiviral drugs and vaccines less effective, because they are specifically tailored to a virus.
Using the coronavirus vaccine.
That’s why we need a new flu vaccine every year—the influenza virus mutates so rapidly that new strains constantly emerge.
The slow mutation rate of coronaviruses means that our immune system, drugs and vaccines may be able to recognize them long after infection, and therefore protect us better.
Still, we don’t know for how long our bodies remain immune to the different coronaviruses. There has never been an approved treatment or vaccine for coronavirus.
We haven’t focused on treating the ones that cause colds, and although scientists have begun to develop treatments for SARS and MERS,
But the pandemic ended before clinical trials of those treatments could be completed.
As we continue to encroach on other animals’ habitats, some scientists say
That a new coronavirus jumping to humans is inevitable—but if we investigate these unknowns, it doesn’t have to be catastrophic.
What is meant by RNA virus?
RNA viruses are small with fewer genes, which means they infect many hosts and replicate quickly in those hosts.
In general, RNA viruses do not have proofreading mechanisms, while DNA viruses do.
So when an RNA virus replicates, it is more likely to make mistakes called mutations. Many of these mutations are deleterious or even harmful.
But some make the virus better suited to certain environments—such as a new host species. Pandemics often occur when a virus jumps from animals to humans.
This is true of the RNA viruses that caused the Ebola, Zika and SARS epidemics, and the COVID-19 pandemic.
Once in humans, the virus still mutates—usually not enough to create a new virus, but enough to create variants or strains of the original.
Coronaviruses have some important differences from most RNA viruses.
They are some of the largest, which means they have the most genes. This creates more opportunities for harmful mutations.
