The dissemination of the 2019 novel coronavirus (2019-nCoV) is presenting the planet with a new health emergency response or threat to health. The virus emerged in bats and was disseminated to humans in December 2019 via still unknown intermediate species in Wuhan, China. It is disseminated by inhalation or breaks out with infected droplets and the incubation period is between 2 and 14 days. The symptoms usually include high body temperature, cough, sore throat, dyspnea, low energy or tiredness, and weakness. The condition is moderate in most people; but in the elderly and those with comorbidities, it advances to pneumonia, acute respiratory distress syndrome (ARDS), and multiple organ failure. Popular research work includes normal/low WBC with upraised C-reactive protein (CRP). Treatment is generally supportive and requires home seclusion of suspected persons and rigorous infection control methods at hospitals. The Covid-19 has lower fatality than SARS and MERS. Among the proposed therapeutic regimen, hydroxychloroquine, chloroquine, remdisevir, azithromycin, toclizumab, and cromostat mesylate have shown promising results, and the limited benefit was seen with lopinavir-ritonavir treatment in hospitalized adult patients with severe COVID-19. Early development of the SARS-CoV-2 vaccine started based on the full-length genome analysis of severe acute respiratory syndrome coronavirus. Several subunit vaccines, peptides, nucleic acids, plant-derived, and recombinant vaccines are under pipeline. Research work, development of new medicines and vaccines, and efforts to reduce disease morbidity and mortality must be encouraged to improve our position in the fight against this disease and to protect human life.
