History, Diagnosis, and Treatment of Coronavirus Disease 2019 (COVID-19)

The Coronavirus Disease 2019 (COVID-19), also known as a novel coronavirus (2019-n- CoV), reportedly originated from Wuhan City, Hubei Province, China. Coronavirus Disease 2019 rapidly spread all over the world within a short period. On January 30, 2020, the World Health Organization (WHO) declared it a global epidemic. COVID-19 is a Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) evolves to respiratory, hepatic, gastrointestinal, and neurological complications, and eventually death. SARS-CoV and the Middle East Respiratory Syndrome coronavirus (MERS-CoV) genome sequences similar identity with 2019-nCoV or Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). However, few amino acid sequences of 2019-nCoV differ from SARS-CoV and MERS-CoV. COVID-19 shares about 90% amino acid sequence similarity with SARS-CoV. Effective prevention methods should be taken in order to control this pandemic situation. To date, there are no effective treatments available to treat COVID-19. This review provides information regarding COVID-19 history, epidemiology, pathogenesis and molecular diagnosis. Also, we focus on the development of vaccines in the management of this COVID-19 pandemic and limiting the spread of the virus.
