The first coronavirus strain (229e "alpha") was identified at the University of Chicago in 1965 and was believed even then to have originated in bats. The four major strains of coronavirus that have been identified since then have also been zoological in nature. So this current pandemic (HCoV-NL63, aka "COVID-19") is just the latest in a long line of viruses passed from animals, most likely bats, to humans. It appears the origin point of Tran species transmission happened in Wuhan China.
The very first discovery of the coronavirus took place in 1960. The early discovered was an infectious bronchitis virus which was found in chicken’s respiratory tract and then later in 1963 two more cases were discovered from the nasal cavity of humans named As Human Corona Virus 229E and Human Corona Virus OC43 as a result of zoonotic transmission (transmission of disease from animals to humans). Since then the cases have occurred in several other forms in very small numbers. Many shreds of evidence in history state that corona has always spread from an animal to a human, for instance, SARS was transmitted from bat to a human being, MERS which is also called camel flu was transmitted from camel to human, But this time the scientist are having difficulty in identifying the animal responsible for COVID-19.
What is a coronavirus?
Coronavirus, now declared as a pandemic is a large cluster of viruses that causes illness in animals and humans. In humans, coronavirus usually spreads when they cough or sneeze droplets or saliva of an infected person come in contact with the uninfected person. The outbreak of this virus occurred in Wuhan, China in December 2019 and has been spreading across the globe since then.
What is COVID-19?
Covid-19 is the disease caused by SARS-COV-2 virus. This virus has shown itself to be very contagious with short incubation period in humans. The pandemic however will end as you will be able to appreciate when you get some idea about the virus and some of its prominent properties. You will however continue to get sporadic outbreaks with possibly seasonal patterns.
You cannot have reliable vaccine as in small pox and polio. The COVID is caused by an RNA virus and likes to mutate quiet comfortably.
What is SARS-COV-2 virus?
Let us now have a very brief glimpse of this virus. It belongs to the family of virus known as Corona virus. Perhaps it was happily living in some exotic creatures and ended up unwittingly in a human host as humans are pretty much like cockroaches when it comes to food habits. It did not mean to be so aggressive and was happily living in the previous natural host. In the humans it found it easy to multiply and spread largely through contact. It has shown itself to be highly contagious.
About the infection:
1. It is really enormous in size (cell is around 400-500 nm distance across), so any typical veil (not simply the N95 highlight) ought to have the option to sift it through. In any case, when somebody who's contaminated sniffles before you, it will take an incredible 3 meters (around 10 feet) before it drops to the ground and is never again airborne.
2. At the point when the infection drops on metal surface, it will live for at any rate 12 hours. So recall whether you interact with any metal surface, wash your hands with cleanser altogether.
3. The infection can stay dynamic on texture for 6-12 hours. Ordinary clothing cleanser should slaughter the infection. Yet, in the event that you are truly stressed, you can include some non-chlorine fade or oxygen blanch. For winter apparel that doesn't require every day washing, you can put it out under the sun to kill the infection.
What are coronavirus symptoms?
Coronavirus has flu-like symptoms. Here is a list of coronavirus symptoms
That have been consistent amongst patients all around the world:
· High body temperature or constant fever.
· Extreme levels of tiredness and fatigue.
· Dry cough.
· Difficulty in breathing.
Along with the above listed symptoms, some patients may also have:
· Pervasive headaches on one or both sides.
· Nasal congestion.
· Runny nose.
· Sore Throat.
As these are very generic symptoms, they are often misdiagnosed by the patient. This is why if you observe one or more of these symptoms, it is advisable to consult a physician. For the ones who have contracted the infection might not experience immediate severe symptoms. These symptoms grow over a couple of days and then become serious.
Coronavirus pandemic will be over
It depends where you live and how many coronavirus cases there are in your country/area but, once numbers go down steadily, your government will want things to get back to normal. Mainly because governments need money (taxes) to run the country; businesses need money to pay their staff and people need money to live. That's the economy! The economy doesn't work if everyone stays at home. The problem is balancing the needs of the economy with saving people’s lives.
The corona virus likely will never end soon, scientists and health experts believe that it will be like the influenza, and will have cases year round, in the winter months. Of course, might be it won't continue as intense as it is now, and world-wide case numbers and deaths will drop significantly.
Many countries are trying to come up with a vaccine to help limit the amount of people that get sick
But the scientifically, The Coronavirus as we know it has found a good host. And when a virus finds a good host, it is part of the host species’ existence long.
It appears that this Coronavirus is very adept at mutation, which is how it got to humans in the first place. So no matter what vaccination is brought out, Coronavirus will circumvent it with mutation, just like the ‘flu does. This mutation can make it more aggressive or less aggressive.
How an Epidemics or pandemic end in one of three ways:
1- Everyone who can get infected gets infected (see Black Death in Medieval Europe, Smallpox in Age of Exploration Americas, and Spanish Flu in 1918–1920)
2- Government action finds everyone who is sick, quarantines them, and prevents further spreading (see Wuhan China, 2020, SARS in China In 2002, Ebola in West Africa, 2018)
3- Transmission slows in warm/dry weather (see influenza, every year).
