There are several coronaviruses, some of which we don’t hear about in today’s society.
The viruses that we are aware of are South African Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). Both viruses are caused by the coronavirus and originated in animals before transferring to humans. Bank in 2002, SARS spread throughout a lot of countries undetected, causing global panic and infecting over 8000 people with a death rate more than 750 people.
Other coronaviruses we don’t tend to hear about much. There are 7 human coronaviruses in total and they are split into 4 main sub-groupings known as alpha, gamma, beta and delta.
Human coronaviruses were first identified in the 1960’s. The names are;
- 229E (alpha coronavirus)
- NL63 (alpha coronavirus)
- OC42 (beta coronavirus)
- HKU1 (beta coronavirus)
- MERS-CoV (beta coronavirus that causes MERS)
- SARS-CoV (beta coronavirus that causrs SARS)
- SARS-Cov-2 (novel coronavirus that causes COVID-19)
According to the CDC people around the world commonly get infected by the first 4 viruses (1-4) on this list.
Sometimes, coronaviruses that infect animals can evolve and transfer to humans. The last 3 viruses on this list (5-7) are the most recent examples of this.
I hope this has given you a better understanding of the Pandemic that the entire world is currently dealing with.
