Abstract
Environmental change, climate warming, increasing population density, high migration activity and other factors are provoking the emergence and spread of new infections around the world. The emergence in December 2019 of diseases caused by a new coronavirus ("coronavirus disease 2019") has already gone down in history as not a disease of minor importance, but a disease of great magnitude engulfing the entire humanity. It is known that the most common clinical manifestation of the new infection is pneumonia and, in a large proportion of patients, respiratory distress syndrome. In our article we present a brief analysis and literature review of the epidemiological and epidemiological picture, in addition, we note the etiopathogenesis and some of the nuances of the disease.

Summary
In the new millennium mankind encountered infectious diseases that nobody knew about. Coronavirus infection is an acute viral disease with predominant involvement of the upper respiratory tract, caused by an RNA-containing virus of the genus Betacoronavirus of the family Coronaviridae. In 2012, the world was confronted with a new coronavirus (MERS-CoV), the causative agent of Middle East respiratory syndrome, belonging to the genus Betacoronavirus. On 11 February 2020, the International Committee on Virus Taxonomy assigned its own name to the causative agent of COVID-19, SARS-CoV-2. The new coronavirus SARS-CoV-2 is a singlestranded RNA-containing virus belonging to the family Coronaviridae, belonging to the Beta-CoV B lineage. It is classified in pathogenicity group II, as are certain other members of this family (SARS-CoV, MERS-CoV). The surface of objects at 18-25 °C maintains viability from 2 to 48 hours
