Abstract
The last month of 2019 harbingered the emergence of a viral outbreak that is now a major public threat globally. COVID-19 was first diagnosed and confirmed in a couple of cases with unknown pneumonia; the patients lived in, or travelled to, Wuhan, the capital of China's Hubei province. People now face a complex challenge that deserves urgent intervention by all involved in medical healthcare globally. Conventional antiviral therapies or vaccines are the most referred means of tackling the virus, but we think establishing these ideal management strategies is presently far-fetched. In-house isolation or quarantine of suspected cases to keep hospital admissions manageable and prevent in-hospital spread of the virus, and promoting general awareness about transmission routes are the practical strategies used to tackle the spread of COVID-19. Cases with weakened or compromised immune systems-for example, elderly individuals, young children, and those with pre-existing conditions such as diabetes, cancer, hypertension, and chronic respiratory diseases-are particularly more susceptible to COVID-19. Hopefully, cumulative data using whole-genome sequencing of the SARS-CoV-2 genome in parallel with mathematical modeling will help the molecular biologists to understand unknown features of the pathogenesis and epidemiology of COVID-19.
