BACKGROUND Emerging infectious diseases pose a great hazard to public health and the global economy. A novel coronavirus, SARS-CoV-2, causing coronavirus disease 2019 (COVID-19), emerged from Wuhan, China, in December 2019. Since then, it has spread globally causing a global health emergency of inconceivable magnitude, with significant morbidity and mortality. There is the need for clinicians and health care providers to understand and gain knowledge of the different aspects of the disease as it evolves. OBJECTIVE We reviewed existing literature on COVID-19 in order to present a synopsis of current understanding of the disease. METHODS Using PubMed, Embase and Medline, articles published between January and April 2020 on Coronavirus disease 2019 (COVID-19), and resources from World Health Organisation were analyzed in order to have an understanding of the clinical characteristics, transmission dynamics, virology, diagnostic possibilities, prevention, management approach, controversies and impact of COVID-19 on the healthcare workforce. RESULTS Our review revealed that COVID-19 patients present with a myriad of symptoms, ranging from mild to severe respiratory disease, which can often be fatal. The mode of transmission via droplet infections makes it unduly contagious and difficult to control. Currently, antiviral drugs or vaccines are being developed to manage this condition. CONCLUSION There is urgent need for potent antivirals and vaccine to manage those infected with COVID 19 and prevent infection. Global efforts need to be unified in combating this public health emergency and flattening the curve of spread.
