COVID-19, SARS-CoV-2, Pandemic, Vaccines, Virus
Currently, more than 500 million individuals have been infected with SARS-CoV-2 and more than 6 million have died from this deadly virus in 222 countries. This mini-review sheds light on some of the important aspects of COVID-19 disease and the information that the researchers have gathered so far regarding epidemiology, virology, pathogenesis, diagnosis, treatment, variants of concerns, and vaccine development. We also summarize the timeline for the development of the disease and milestones achieved so far so that the readers can grasp the timing of some of these critical events. Notables are the rapid development and regulatory approval of diagnostics, antiviral medicines, and vaccines within a year of the virus's discovery. Because the development of understanding the mechanism of this viral infection and drug design occurred concurrently, we provide a chronology to help readers understand the progression of research findings as well as their interpretation. Scientists from across the globe are collaborating to combat this pandemic. This analysis also identifies future directions for research and development in these areas.
