History of Coronavirus

Coronavirus is considered to be a disease belonging to an extensive family of viruses that can negatively affect animals and humans. This virus can cause both flu and severe respiratory problems. 

COVID-19 is the latest virus belonging to the coronavirus family that has been discovered and that has affected most countries in the world.  

It was declared a pandemic and has affected the world population causing symptoms, including dry cough, fever, tiredness, headache, nasal congestion, sore throat, diarrhea, and more. 

This disease has severely affected many people, especially older people, causing death in a large percentage of the time. COVID-19 has taken the lives of millions of people on the planet. 

Origins of the Coronavirus 

Although most people knew about the coronavirus in 2019-2020, the truth is that it is a disease whose ancestors date back to the 9th century B.C. Throughout history, several viruses belonging to the coronavirus family have affected people’s health. In the 1990s, scientists managed to identify several of these viruses throughout history through various studies. 

Each of these diseases presented a different name according to the time. Betacoronavirus arose in the year 3,300 B.C.; the Deltacoronavirus in the year 3,000 B.C.; The Gammacoronavirus in the year 2,800 B.C. and the Alphacoronavirus in 2,400 B.C. 

Similarly, this virus affected many people during the 19th and 20th centuries, specifically in the 1890s. It was thought to be a human-linked bovine coronavirus, but scientists were unable to determine whether it was actually due to the bovine or a mutation. Years later, in the 1950s, OC43 appeared, which was a virus related to different types of bats. 

The most recent viruses before the appearance of COVID-19 originated in 2002 in China and later in 2012 in Saudi Arabia. The disease that arose in China was named as the SARS-CoV virus, which had a related origin to bats. The one belonging to Saudi Arabia was called MERS-CoV and was closely linked to camels. The last one was transmitted to humans through zoonosis. 

COVID-19 History 

The COVID-19 virus became known in December 2019 when a pneumonia outbreak originated in Wuhan, Hubei, China. At the time, that outbreak was of unknown cause. 

It started on December 29 when the CCDC (Chinese Center for Disease Control and Prevention) received four patients with severe pneumonia. Those people worked in the Huanan market that was located in that city. 

This situation was very unexpected and suspicious, so they began to investigate that market to try to obtain some evidence. On December 31, Wuhan informed the WHO (World Health Organization) about the condition of 27 people who had been diagnosed with pneumonia. 

This situation caused the market to close on January 1 due to prevention. Days later, Chinese scientists began conducting various tests to verify the cause of the disease. On January 12, 41 people affected by this virus had already been confirmed, suffering from discomfort, dry cough, fever and respiratory problems. 

COVID-19 began to expand rapidly. On January 19, they confirmed 17 more cases and also the existence of two infected abroad. One of them in Japan and the other in Thailand. 

This situation began to generate panic causing the WHO to declare a public health emergency of international concern. It intended to prevent the strong impact of the disease on less developed countries. 

On January 28, an important delegation belonging to the WHO traveled to China to meet with the leaders of that country and discuss specific issues. The idea was to understand the situation better and offer all the necessary help to the country to prevent the spread of the disease. 

The virus quickly spread to more than 100 territories across the planet and China. For this reason, the WHO declared COVID-19 a global pandemic on March 11, 2020. On March 13, the Solidarity Response Fund against COVID-19 was established to receive donations from individuals or companies to support the organization and the population during this pandemic. On the 26th of that month, more than 500,000 cases had already been confirmed worldwide. 

From that moment, all the governments of the world began to implement strategies to stop the expansion of COVID-19. All the commerce started to close except for supermarkets and medical establishments (hospitals, clinics, pharmacies) since they were the most important places during the stressful situation. 

All trips to other cities and countries were canceled, and governments ordered social isolation, confinement, and quarantine. Everyone had to stay home to prevent the virus from spreading further. Only one person per family could go out to buy food or medical supplements. 

This event has not only affected people from the point of view of health but also the socioeconomic situation worldwide. The moment people found out about the appearance of this virus, fear invaded them, and they began to make compulsive purchases. 


Due to the socio-political problems that various countries present against China such as Russia and the United States, rumors began to arise about the possibility that COVID-19 was created in a laboratory. Many thought that the human being had created this disease with the aim of initiating a biological war between world powers to end the economy. 

Those rumors were quickly denied after a group of scientists ruled out that possibility thanks to a decoding of the genetic material of this virus. That test was powerful enough to determine that the disease had naturally evolved.
