The coronavirus is a virus that originated in Wuhan, China. This virus has been declared a pandemic, and thousands of people have died worldwide. Even now, the number of infected and dead continues to rise considerably every day.

This virus inevitably brings back memories of another outbreak, SARS (Severe Acute Respiratory Syndrome), which is also caused by a coronavirus. SARS killed 774 of the 8,098 people infected in 2008. But COVID-19 is also being compared to the Black Death. Why? Because it is estimated that before a cure for COVID-19 is found, it will have killed at least one million people.

How easily is this virus transmitted?

According to scientists, an infected person can transmit the virus to between 1.4 and 2.5 people. This figure corresponds to the virus’s reproduction rate, although this number can vary at any time, since, according to studies, the virus is constantly mutating.
