Updated insight into COVID-19 disease and health management to combat the pandemic

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19 disease in humans and is the responsible viral agent for the currently ongoing pandemic. Early cases of COVID-19 were reported from Wuhan, Hubei province of China, the likely birthplace of this outbreak. Currently, over 92 million people in the globe are actively battling this virus, and over 2 million individuals have already succumbed to the disease. The high human-to-human transmission capacity of the virus is among the primary causes for such a rapid global spread of COVID-19. In humans, it causes acute to severe respiratory distress in the form of pneumonia. The presentation of clinical features of the disease ranges from mild in healthy adults to severe among individuals with weakened or immunocompromised immune systems and the elderly. Thus, increasing patient cases of COVID-19 warrants a growing demand for medical attention that is eventually overburdening our health care systems. Rapid detection of COVID-19 in suspected individuals and isolation are among the crucial intervention norms in health management strategies to control the COVID-19 pandemic, in addition to strict observance of public hygienic practices such as reduced public gathering, use of facial masks, and practicing of social distancing. This chapter provides an overview of the epidemiology of COVID-19 and the current classical health management strategies and issues to tackle this pandemic. It particularly highlights the role of standard as well as novel biomolecular diagnostic techniques as a tool for successful implementation of such public safety measures issued by medical policy makers and the governing bodies.
