Abstract


December 2019 was marked by the emergence of a novel human coronavirus (SARS-CoV-2) in Wuhan, China, which causes a variety of symptoms, commonly known as COVID-19. The high contagiousness, rapid worldwide spread and case fatality rate have led to a sharp increase in number of infected persons and related deaths, which subsequently resulted in the recognition of the COVID-19 outbreak as a pandemic by the World Health Organization. SARS-CoV-2 is an ongoing challenge not only for the healthcare professional but also for the general population. The aim of this literature review is to summarize the currently available data on COVID-19 regarding the origins, pathogenesis and epidemiology.


Keywords
