A year of Combat Against Coronavirus

22 April, 2021  |  Raja


The outbreak of COVID-19 has forced everyone in the world to change their habits. We’ve changed how we eat, live and socialize; basically, our entire life. The COVID-19 outbreak was first recorded in the Chinese city of Wuhan at the end of 2019. By the start of 2020, it went on to spread across the entire world. Hundreds of countries were affected by this virus. Countries went into lockdown; people were advised to stay isolated and avoid unnecessary socialization. After a year of combat against Coronavirus, how well have we really fared?

What is Coronavirus?

Coronavirus is a virus covered in pointed protein molecules that appear like a crown. There are hundreds of known coronaviruses, but seven are known to affect humans and cause disease. The Coronavirus SARS-COV was responsible for the SARS outbreak, MERS-COV for the MERS outbreak, and SARS-COV-2 has caused the current COVID-19 pandemic. Out of the seven viruses that affect humans, four tend to cause colds. Two of these mildly infect the nose and throat, whereas the other two infect the lungs and cause a more severe illness. The seventh — the one that causes COVID-19 — has features of each of the earlier viruses and spreads quickly, severely impacting the lungs. 

Viruses cannot reproduce independently; they must invade the cell and take over its processes to be able to grow and multiply. This type of Coronavirus is unlike any the world has seen before. How the virus affects an individual varies; some suffer from mild symptoms like runny nose, sore throat, cough and fever, whereas others might experience severe pneumonia. Additionally, for some people, it can even be fatal. Until now, there have been 128,950,780 COVID-19 cases reported worldwide in over 219 countries, and 2,818,911 people have lost their lives to it.

So, where did the novel COVID-19 virus originate from?


How did Coronavirus Start? 

Coronavirus is a zoonotic virus that can spread from one species to another. A zoonotic virus is born when an animal is infected by two related viruses. For example, some experts believe that the 1918 Spanish Flu started when a bird with Bird Flu and a human who had seasonal flu came into contact with a pig. Those two viruses couldn’t infect each other, but both could infect the pig. The pig then infected the humans with this new virus which their immune system couldn’t recognize. This kind of contact is unlikely in natural environments.

According to experts, we’ll see more diseases like this originating in the future. The world health organization has been investigating the origin of the COVID-19 virus at the Huanan Seafood Wholesale Market in Wuhan. The head of mission, Peter Embarek told the media that their research suggests the virus probably jumped from bats to humans by an intermediary species. They also told the press that there was no indication of the Coronavirus before 2019.
