Abstract
For most people on our planet, the beginning of the current COVID-19 pandemic was a complete surprise and looks like a sudden disaster. However, experts do not have the right to argue in this way, since the cause of this disaster has long been known to medicine. Moreover, similar epidemics of this infection have already been observed in the recent past, had a very similar scenario, but with less coverage of the population and territories. The identity of the causative agent of today’s pandemic with the two previous outbreaks, SARS in 2002-2004 and MERS in 2012-2013, is even reflected in the terminology-CoV, CoV-1 and CoV-2 [1].
