Coronavirus: A lesson to humans or a misfortune? The ultimate study of Coronavirus or COVID-19 and the history of evolution.
While in the Last weeks of 2019 when the world was ready to welcome the year 2020, many local hospitals in Wuhan, China reported in an unusual number of cases who had severe and Ammonia without clear cause and were not responding to any form of the existing vaccine or medicines.
Soon, after a seafood market in the region was linked to all these cases, this was a wholesale seafood market that had about thousand dollars selling fishes, chickens, snakes, rabbits, and many other wild animals.
These cases showed a very high human to human transmission rate which was further increased as a days for the initial hypothesis was formulated that this was a new type of coronavirus that ward in the animals being sold in the seafood market of Wuhan.
This resulted in a fear that it could be similar to the SARS epidemic of 2002 which infected a thousand people and killed 774. They all were wrong because this was going to be something much worse. By early January 2020, about 59 suspected cases were picked up from all local hospitals in Wuhan and isolated in the nearby hospitals and around 1598 cases were found of which 41 were confirmed with the 2019 Novel coronavirus.
Corona virus isolation was too late and before they were isolated these cases had infected hundreds of others that eventually infected thousands and the starting the 2019 novel corona virus epidemic which started as a localized epidemic in the central China quickly spread to involve all other Chinese provinces in a manner of few weeks.
This threat was escalated by the Chinese new year and thousands of tourists out of the home the situation became very tense when cases in other countries were also reported which were transmitted by international Travellers.
The first cases reported from Vietnam and soon after several new cases reported from Germany, Thailand, Japan, Australia, the United States, Russia and other new countries leading to a global panic situation. The epidemic cost its first life on January 19. While you are reading on 8th April 2020 Novel coronavirus epidemic has led to more than 1 282 931 confirmed cases of which 72 774 are dead, more than 211 countries have been affected with major outbreaks in Central China, The United States, Spain, Germany, South Korea, Italy, and Iran.
Due to this epidemic, you can imagine the gravity of the situation by looking at this path WHO declared the epidemic as a Global Health emergency as on 30th January 2020.
Delta Airlines, United Airlines, and American Airlines all have completely suspended a flight to China by several other airline companies that have severely reduced the number of daily flights. The US government has temporary band entry into the United States by any foreign national who was travel to China in the past 14 days.
Along with the Chinese stock market, International stock markets are constantly crashing and this has led to a global economic slowdown already
Coronavirus? What is it?
The word coronavirus is derived from the Latin word meaning crown for hair which refers to the characteristic appearance of this virus. It consists of certain genetic material surrounded with and all of proteins spikes this gives it in the appearance of a crown and Crown in Latin means Corona.
Coronaviruses are a group of viruses that cause disease in mammals and birds, these are RNA viruses with the genome of 26-32 base pairs. The new coronavirus is have been detected every few years with the first one’s been discovered in 1960 is which cost mild respiratory infections in chickens since then the number of different coronaviruses has been discovered mostly of a team birds and other small warm-blooded animals.
These viruses easily mutated in animals. they circulate. In the close contact of humans with these animals, these viruses can jump from the animal to the human to start a new disease. Coronavirus has already infected humans during the SARS coronavirus which led to the SARS epidemic in 2003. The MERS coronavirus and the human Coronavirus NL-63.
The latest edition to these names is a novel coronavirus formerly known as the “Wuhan Coronavirus”. New viruses are detected all the time its known species circulate in a variety of animals sometimes these viruses can make a jump from animals to humans this is known as spillover and can be due to a number of reasons like mutations in the virus itself or increased close contact between humans and animals.
For example, MERS coronavirus is known to be transmitted from camels to humans and SARS coronavirus from civet cat. The animal reservoir of 2019 Novel coronavirus is not clear yet, many of the early coronavirus cases linked to the south China seafood market in Wuhan but an earliest documented case that has been traced back to 1st December had no connection to the market surprisingly. Coronavirus: A lesson to humans or a misfortune?
How this virus spreads from one person to another is not completely understood yet but we know that the most common way it has been spreading is through droplet infection. It is when a person who is infected coughs or sneezes and releases virus particles that remain suspended in the air and is picked up by another person.
It is also transmitted through things that are infected person has been closed in contact with like use towels, clothes, switches, keys, and door handles. Those who are the highest risk are people who are in close contact with animals like animal market workers and those who are taking care of infected like family members doctors or nurses.
WHO has coined the term 2019 Novel coronavirus as an acute respiratory disease to describe the disease caused by this virus indicating that most of the symptoms of the disease related to the respiratory system. Now from what we know is that there can be a number of symptoms ranging from mild to severe. The mild cases can be seen in the present with fever, cough, shortness of breath and severe once can lead to pneumonia, Kidney failure, and death.
The most widely used test to detect the Coronavirus infection is the PCR (polymerization chain reaction) this test detects the minute quantities of the genetic material of the virus and amplifies it. There is currently no vaccine to prevent the 2019 Novel coronavirus infection, the best way to prevent infection is to avoid being exposed to this virus.
However, CDC always recommends everyday preventive actions to help prevent the spread of respiratory viruses which includes that’s like washing your hands with soap and water for at least 20 seconds, covering your mouth and nose while coughing and sneezing using an alcohol-based sanitizer that contains 60% alcohol or more and avoids touching your eyes nose and mouth with hand wash hands stay home when you are sick and avoid close contact with people who are sick.
The vaccine for coronavirus is already underway scientists believe that research of the MERS vaccine which was also coronavirus will make this job easier and hospitals are testing antiviral drugs to see if they have any impact. On the ratio of deaths to known cases appears to the figures are unreliable it is far to simply stick to divide the number of deaths by the number of cases to calculate the death rate to get a figure of around 2% at this stage of the outbreak but it depends upon a range of factors like your age, sex, General Health and health system you have.
Thousands of patients are still being treated and we do not know if any of those cases will die the death rate could be higher it is because of the size and density of the population and close contact with animals harboring viruses.
The short answers this question is absolutely as many of those who contract coronavirus will experience only mild symptoms that include fever, coughing, and respiratory problems. Most people are expected to make a full recovery, but they can cause a particular risk for elderly people and doors with pre-existing problems like diabetes or cancer so I hope I am able to share some knowledge about the 2019 Novel coronavirus pandemic with you.
