Introduction
Master. Marco Giovanni, 5 years old, son of an Emergency physician wished his father - “Felice anno nuovo” on the eve of 1st Janurary 2020. A 7 years Indian girl, Miss. Pooja, daughter of a nurse, wished her mother “navavarsh kee shubhakaama” on the same eve. The same day the World Health Organisation (WHO) was informed of cases of pneumonia of unknown aetiology detected in Wuhan City, Hubei Province, China. Neither did they know what is about to loom in the next few months nor they knew that the reporting from the Wuhan province would stuck grieve in their tender hearts. Lockdown, quarantine, self-isolation, personal protection equipment, social distancing have become words of daily usage. Chimneys of large factories stop to eject smoke. Stock markets go crashing down. Gyms are considered unhealthy because of crowd. Covering the face was considered essential. Handshakes changed to Namaste. Mecca and Vatican City are closed. Hospital reserve beds for future crisis. Dr. Ignaz Semmelweis’ hand-wash was being reinforced. There is one link to all these events - Coronavirus, Covid-19, SARS-CoV-2 - a 60–140 nm microbe. It is not an exaggeration to say that the symptoms, incubation period, natural history or treatment of this virus is yet to be described to the fullest. China reported its first victim of COVID -19 on January 11th, 2020. Two months later, the WHO declares COVID-19 as a pandemic (March11th, 2020). Knowledge of this virus is evolving. World leaders, health care workers and health organisations take all possible measures to close the gates for this deadly virus and keep it under control.  The impact of this virus extends to the health care system, economy, education and politics.
