The world has experienced an increased incidence and transboundary spread of emerging infectious diseases due to population growth, urbanization and globalization over the past four decades. Most of these newly emerging and re-emerging pathogens are viruses. On an average, more than two new species of viruses infecting humans are reported worldwide every year most of which are likely to be RNA viruses. Surveillance System, early detection, identification, characterization, containment, control and ultimately prevention of the emerging infectious diseases will require a good, functional national public health surveillance system. There is an urgent need to develop a network of diagnostic laboratories, especially in countries where epidemic infectious diseases are weak. Need for real-time early detection of disease needs innovations in biomedical technology. Contact-tracking is essential. Rapid testing facilities must be available to all populations in all countries. The COVID 19 pandemic will be a definitive moment in world history and beremembered by us all. What will also be remembered is how we behave with each other. Tackling nCoV is the biggest challenge to face the World. An effective treatment and development of vaccine must be found on a war-footing.
