**1. Introduction**

One of the major issues of the 21st century, without any doubt, is the viral respiratory disease discovered at the end of 2019, the COVID-19. Using nextgeneration sequencing, the pathogen related to COVID-19 was described as a novel coronavirus, which is related to the SARS-coronavirus described in 2003, mainly in Asia, from the molecular and phylogenetic aspects [1].

A severe respiratory disease was reported in Wuhan, Hubei province, China. Epidemiological investigations have suggested that the outbreak was associated with a seafood market in Wuhan [2].

The first case reported in the medical literature was that of a 41-year-old man who was hospitalized in the Central Hospital of Wuhan. The patient was admitted to the hospital reporting an extensive set of symptoms since one week before his admission on December 26, 2019, which included dry cough without sputum, fever, weakness, chest tightness, and widespread pain. Normal signs were observed at physical examination on abdominal, cardiovascular, and neurological features.
