Abstract
Recent COVID-19 pandemic has caused the greatest crisis in human civilisation worldwide. Initially started in Wuhan, China it has gradually spread all over the world due to the time taken by the people to understand the seriousness of the disease. Initial symptoms are unremarkable and typical of upper respiratory tract viral infection, followed by dry unproductive coughing, low grade fever and ultimately full blown feature of pneumonia requiring hospitalisation and respiratory assistance including ICU and ventilation. Older adults, immunocompromised patients and those with sev-eral co-morbidities fall in higher risk categories irrespective of age. In this paper the origin, spread of infection and virulence, preventive steps, diagnosis and recent trends in clinical management is discussed in detail. Future implica-tions on socio-economic point of view is mentioned in global as well as in national perspective.
