COVID-19: The new reality

Coronavirus in general is any of a family (Coronaviridae) of single-stranded RNA viruses that have a lipid envelope studded with club-shaped projections, infect birds and many mammals including humans, and include the causative agents of MERS, SARS, and COVID-19. They cause mild to severe or even fatal diseases in the human body. These diseases are associated with respiratory infections. The natural reservoir for coronaviruses is the animal hosts. New strains emerge from this reservoir, infect an 'intermediate' host, and from there infect people. The viruses may then be capable of being transmitted from one person to another.
