In today’s world new emerging infectious diseases, particularly those that directly infect respiratory system like Zika virus and severe acute respiratory syndrome (SARS) are posing a major threat to public health. Regardless of intensive research efforts being put, where, when and how these new diseases appear remains in the realm of unknown. A new disease called the coronavirus disease (COVID-19) which adversely affects the respiratory system has been reported recently in China particularly in Wuhan city of Hubei province. The ongoing worldwide outbreak of this disease was declared both pandemic and Public Health Emergency of International Concern by World Health Organization. The International Committee for the taxonomy of Viruses has named this virus as severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). This virus initially originated in bats and then using, yet an unknown intermediary animal was acquired by humans in Wuhan, China in December 2019.  There have been around 2,214,327 reported cases of coronavirus disease 2019 (COVID-2019) and 148,889 reported deaths to date (17/04/2020). The transmission of the disease is caused by encountering or inhalation of the infected droplets and the virus has an incubation time ranging from 2 to 14 days. The major symptoms of this disease include sore throat, cough, fever, fatigue, shortness of breath and malaise. Many people also remain asymptomatic. This review article highlights the details about coronavirus, its genome structure, disease, epidemiology, and its treatment.
