Scientists believe the earliest form of coronavirus existed around 10,000 years ago (8000 BC). Today, the novel coronavirus, known as SARS-CoV-2, is a member of a larger family of coronaviruses. This SARS-CoV-19 has been named a pandemic by the World Health Organization (WHO).

Today, seven coronaviruses can infect humans, but the first identified human coronavirus case was in 1965. You should know that there is an evolution of coronavirus hosts, ranging from different bats and animal species to humans.

The deadly coronavirus, which is the cause of the global pandemic today, originated in Wuhan city, China, in December 2019. However, no evidence links the engineering of the deadly coronavirus to the Wuhan Institute of virology laboratory.


The primary cause of coronavirus is contact between host animals and other animals or humans. Noteworthy, there is a considerable similarity between the coronavirus in bats and the SARS-Cov-2.

There are reports that the earliest coronavirus cases in the Wuhan market originated from seafood and animals. It may have been that the SARS-CoV-2 started to spread to humans from the market.


It is sometimes complicated identifying a case of Coronavirus. This is because it shares symptoms with other widespread illness that continues to plague humans. As such, it is usually necessary for a proper medical consultation, examination, and diagnosis to confirm a case of coronavirus.

Regardless, there remain existing symptoms that may give a hint to the virus. Coronavirus symptoms include breathing difficulties, chest pain, fever, dry cough, fatigue, aches, skin rashes, sore throat, diarrhoea, headaches, etc. Others include nausea and loss of taste or smell. You should know that the coronavirus can also cause infections like bronchitis and pneumonia.

Noteworthy, the symptoms of the coronavirus range from mild to severe. And its impact can be moderate or fatal. Regardless, when there is an exhibition of any of such symptoms, it is best to physically distant oneself. You can then help then get to a hospital or advise them to self-isolate for a while. There are COVID-19 hotlines in most countries today for ease of access.


Coronavirus is a zoonotic disease. The transmission of the virus is between animals, between humans, and from animals to humans. But you should know that the phylogenetic analysis reveals that the SARS‐CoV‐2 is first transmitted between animals, and then from animals to humans.

The coronavirus continues to spread due to physical human contact. Person-to-person contact between infected persons and non-infected persons further spread the virus. Today, coronavirus continues to spread aggressively, extending 30 million cases worldwide.

Also, note that droplets containing coronavirus can stay on physical surfaces or objects for hours. So, non-infected persons can get infected through direct contact with these surfaces.

If such a person touches their eyes, nose, or mouth without disinfecting, the probability is that they will get infected. So this is why experts advise that people wear face or nose masks to avoid viral droplets or contact.

Also, you should maintain good hygiene and dispose of your masks after use to avoid other contamination.

Lives Claimed

Sadly, there have been more than 960 thousand deaths worldwide. But if it is any solace, more than 22 million people have recovered from the deadly coronavirus.

The coronavirus is a fatal virus that can ultimately cause death in humans. And this is often the case with older people or individuals who fail to get immediate treatment. Some even self-diagnose and stay at home.

But you should know that coronavirus has deadlier implications in persons who have preexisting health and nervous complications. So, the chances are that high fatality is mainly due to coronavirus are older people with weaker immune systems or preexisting health complications.

Note that some countries have had it worse than others. Countries like the United States, Russia, Brazil, Russia, and Mexico have witnessed more cases and fatalities than most countries.


Currently, there is no widespread vaccines, antibiotics, or antiviral drugs to combat the virus. As such, best practices suggested by recognised health institutions at the moment are to maintain physical and social distancing.

You may probably have seen people wearing protective face masks when going outdoors. You may have done so yourself. All these are to ensure that people avoid human contact as much as possible.

Also, this is why countries across the globe are imposing lockdown measures and restrictions. Some have even imposed travel bans and restrictions on social gatherings and events. There are isolation centres and medical response units available to handle coronavirus cases for persons who have already infected.

Drug trials and vaccine tests are ongoing to find a cure for the coronavirus. Till then, please, maintain physical and social distancing and adhere to safety measures imposed by the health authorities.
