A review on COVID-19 for medical students

Abstract

It has not been very long since the SARS-CoV 2002 and MERS-CoV 2012 epidemics. Yet again, nature has introduced SARS-CoV-2, also known as COVID-19, a highly virulent strain of the coronavirus that has its origin in the city of Wuhan, Hubei Province, China. Primarily, a zoonotic infection, the virus probably found its way to humans through infected wild bats sold in the Wuhan local market. What makes the virus virulent, is its ability to infect multiple people at once through single index case. This has led to inability to contain the virus with ease posing a significant threat to national and international health-care resources and economies. The objective of this review is to highlight the key features of the novel CoV-19 infection as per existing data for better understanding of the disease.
