ALERT: Shocking Truth of Coronavirus Revealed, China Discovered Coronavirus 15 Years Ago in a cave!
Coronaviruses have a large family of viruses causing illnesses in severity. The first known outbreak of the first was noticed in the 2003 SARS epidemic in China. The viruses made its second outbreak in 2012 in Saudi Arabia with the MERS.
History of Corona Virus:
It is said that the virus first came from the Wuhan seafood market. It is the area where wild animals like bats, snakes, rabbits, and many more are traded illegally. This new coronavirus is passing from animals to humans.
Hence, it is thought that it’s the first time people are infected with this virus. The virus primarily affected the stallholders from the seafood market, especially those who contracted it with the contact of animals.
Several footages of pangolins made it into the news bulletins. This scaly mammal that looked similar to an anteater was considered to have been the leading cause of spreading coronavirus among humans. Did coronavirus exist before? Did it affect humans?
The all-new human Coronaviruses are not new at all. It began in 1965 when two scientists Tyrrell and Bynoe found that they could pass a virus named B814. The virus resided in the embryonic tracheal organ of the humans. The virus culture was then obtained from the respiratory tract of an adult experiencing a common cold.
The scientists demonstrated the presence of an infectious agent by inoculating the medium from the cultures among several humans. It was found that some people experienced symptoms of a cold. However, Tyrrell and Bynoe failed to grow the agent in the tissue culture.
At the same time, Hamre and Procknow succeeded in growing viruses developing unusual properties in tissue culture. These properties became prominent in the samples that have been collected from medical students suffering from cold.
Both the viruses, B814 and Hamre’s virus, 229E, were sensitive to ether. Hence, they required a coating consisting of lipids for infectivity. But, both the viruses did not relate to any known myxoviruses or paramyxoviruses.
During the late 1960s, Tyrrell led a group of virologists for working with human and animal viruses. They studied infectious bronchitis virus, mouse hepatitis, and transmissible gastroenteritis virus of swine.
What shocked them was that all these viruses demonstrated to be the same morphologically, when seen through the electron microscope. This new group of viruses was the infamously known as coronavirus. The term ‘corona’ was used for denoting the crown-like appearance projecting on the surface. Later on, this was accepted as a new set of viruses.
Certain types of viruses caused diseases in diverse animals including cats, dogs, calves, turkey, chickens, mice, rabbits, pigs, and rats, and was described as a coronavirus. Several virologists included the studies of animals, but the research was not limited to only the respiratory problems. The focus of the study was broadened and accepted disorders of other body functions of animals like mice, cats, and rats.
Later on, human and animal coronaviruses were segregated and put under three specific broad groups. These were done based on their antigenic and genetic makeup. The first group consisted of 229E and other viruses. The second one had the OC43, and the final has the avian infectious bronchitis virus along with other viruses related to avian.
A group of scientists around 15 years ago discovered a cave that held identical viruses responsible for killing millions of people today. The viruses that caused SARS and MERS outbreaks were identical to the viruses found in the cave.
The exact of the cave was kept secret for long. Several species of wild bats dwell in the place. In the words of Peter Daszak, President of EcoHealth Alliance these bats carry a “rich gene pool of SARS-related coronavirus”.
Recently, scientists found the closest match of the human coronavirus in a bat in the Yunnan province of China. Furthermore, a study conducted on February 3, 2020, revealed that the genetics of coronaviruses in humans and bats were 96% alike.
It is expected that the bats have passed on the virus to humans. Astonishingly, researchers studying the two types of viruses have found key contrasts between the RDB sites of the two viruses.
Contemplating the diverse perspectives of coronavirus stated by the scientists then and now, it can be considered that the viruses found in bats are not responsible for infecting the people directly. But, the virus is transmitted to humans widely and severely through an intermediate host.
