Ages passed and the world is still facing the novelty pandemics at every crucial interval of the time history. No matter how advanced our technology is, we just can’t stop the initial casualties of the viruses. And now is the time when an Antarctica remains the only place in the world that does not have any confirmed cases of coronavirus (COVID-19).
Must to know FACTS about CoronaVirus
Coronaviruses are common in animals and can be rarely transmitted from animals to humans as well. There are almost 200 types of coronaviruses known yet and some of them are quite familiar to us that we don’t even know. Only 7 of them affects we human.
Endemic: These viruses are regularly found among particular people or in a certain area.
NL63, 229E, OC43, and HKU1 are 4 out of 7 coronaviruses that are considered as endemic and they are responsible for 15-30% of the world’s common cold cases every year.
Epidemic: SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome) are considered as an epidemic.
Pandemic: COVID-19 (Corona Virus Disease 2019) the seventh coronavirus that is considered as a pandemic.
When, where, and How COVID-19 originated?
The COVID-19 is originated from Wuhan province of china at the end of December 2019. Very soon scientists determined that it was a coronavirus but they are still trying to trace the outbreak source.
According to the research done on COVID-19 so far. It is found that the genetic sequence of the new virus is 96% identical to one coronavirus found in bats. And it has been assumed that the COVID-19 is the mutation of the gene of the coronavirus from bat and snake.
How COVID-19 is transmitted from one host to another?
We just can’t count all the measures to know how it is transmitted. There are numerous ways in which COVID-19 can transmit from one person to another person. As it has the potential to stay alive without even a living host for a few days. It can be transmitted by any means like money exchange between us or by keeping close distance with the infected people.
The moment you pick up the infected spoon to eat your delicious food, it gets transferred to your hand. And it will wait for your hand to touch your open organs like mouth nose eyes to get inside. And after then it will multiply itself and take over your immunity system.
So, washing your hands thoroughly at the regular interval of the time & using sanitizer greatly reduces the risk of infection.
What are the Symptoms of CoronaVirus COVID-19?
COVID-19 Symptoms range from Mild to severe. It generally takes 14 days after exposure for symptoms to develop.
Symptoms are very common to Common Flu:
- High Fever above 100-degree Fahrenheit
- Shortness of breath
However, those with a weakened immune system develop more serious symptoms like pneumonia or bronchitis.
Also, there is a high chance that you may never develop symptoms after being exposed to COVID-19.
Why COVID-19, CoronaVirus becomes unstoppable?
Despite its small mortality rate, it is highly transmissible and still can be devastating because if many peoples are infected a small percentage also corresponds to a large number of peoples.
The COVID-19 virus has the potential to transmit from one person to another person without even causing any symptoms to the former one. It is becoming hard to spot the infected one.
That’s why it is said that healthy people are spreading the virus unknowingly because of their strong immunity and old people are dying because of their weak immune system.
However, there is no evidence that children are at greater risk for getting the virus.
How vaccine generally works in Viruses?
We are on a verge of time where almost all the peoples are eagerly waiting for the vaccine against the coronavirus.
But you should know there are two types of work that vaccines should do to eradicate the virus.
- One is anti-spreading work the one that can keep you safe from new infections.
- Another is anti-viral work that will cure you if you are already infected.
The general procedure for how a vaccine works is that it harmlessly shows viruses or bacteria (or even small parts of them) to our immune system. Our body’s defense recognizes them as an invader and then learn how to fight with it. So that if the body is ever exposed to real viruses, it is well prepared to fight against the infection.
Immunization is simply like training our immune system for probable risks.
It was only the first half of January when china shared publicly, the full RNA sequence of the virus Which is now known as the SARS-CoV-2 rather than COVID-19.
If we look at our history of making vaccines for viruses and bacteria. It generally takes 2-5 years because it should be tested rigorously to make sure that it not only works well but also won’t cause any type of dangerous side effects.
The trial methodology of the vaccine formation consists of three phases.
- First of all, it is tested on a small number of healthy adults to ensure no side effects.
- Then it is again tested on a large number of adults in an area where the disease has spread
- Finally, it is tested on thousands of people in an area where the disease has spread.
Each step can last around 7 months, so an optimistic estimate would be one to 2 years.
However, as the whole world is affected adversely and all the brilliant minds of the earth are working on it. So far working with an idea taken from past experiences on the coronavirus diseases, the vaccine could develop in a much shorter time than ever.
The World Health Organization said that it may take 18 months to make the coronavirus vaccine publicly available.
What if COVID-19 CoronaVirus mutates over time?
SARS-CoV-2 is an animal virus. It is already mutated as it gets transmitted to humans from animals. The coronavirus we are taking to our lab for research is likely adapted into humans. If it gets transmitted from humans to human it will allow the virus to sustain various new kinds of situations. Also, if the virus gets transmitted from humans to animals and again animal to human it might mutate into the dangerous possible phase.
The mutation process varies from place to place. It depends on the population density, which includes the number of people infected, and how many opportunities that virus is getting to mutate.
The risk for mutation is always there in the process of vaccine formation. However, the researcher will continue with one of the latest versions of the virus so that the vaccine possesses the greatest chance of being effective
Unlike all the other viruses, the COVID-19 is considered a “hit-and-run” virus. This simply means that when a person is infected, his/her immune system is activated. Then the infection is cleared, not leaving any kind of information to our body, which can be used to train our immune system about that virus.
So as the time elapses and the natural immunity decreases or if it becomes ineffective then there are again equal chances of reinfection.
In the previous cases of the coronaviruses, like in SARS and MERS the cases of reinfections were observed even after a year.
However, we are still unsure about the COVID-19 due to its novelty.
What if we have to live with CoronaVirus?
We don’t even want to think about it. However, as suggested by the WHO the Vaccine formation will take a minimum of around 18 months to be available for the whole world. And with the very high transmissibility rate of the coronavirus infecting peoples of all the countries in the world, we might have to face the situation where we have to adapt our self to live with the coronavirus.
80% of the infected cases don’t even show some symptoms as well. So if we have a strong immune system, we can just live with it.
Conclusion: CoronaVirus facts!
However, Social Distancing is also necessary as it is working well to reduce the transmitting rate. We have to make a habit of it because we don’t have any option left.
