A new public health emergency has arisen in the world due to the spread of the 2019 novel coronavirus (2019-nCoV). The deadly virus had its first origin from Wuhan, Hubei Province, China. As per the World Health Organization report, there have been around 4,628,903 confirmed cases of COVID-19 and 312,009 deaths globally to date (May 18, 2020). The mode of transmission of this disease is through close contacts (about 6 feet) mainly via respiratory droplets of infected individual. Estimated case fatality rate varies between 2 and 3. In the absence of definite treatment for COVID-19, the evidence- based supportive care with preventive measures is the only way known so far for its management. In this review, we summarized the existing research results to describe the current pandemic of COVID-19.
