Don’t estimate a creature by its appearances and size as it may be useful as well as dangerous to any extent. This old saying by our forefathers has been proved true by the noval corona virus –which is so small in size that can’t be seen with our naked eyes. This small fellow has shaken the whole world. Even the largest and strongest economies could not be spared from the sting of this microscopic virus. India is not an exception. The first COVID-19 infection was observed on 12th December ,2019, in Wuhan( in China). WHO declared it a pandemic on 11th March, 2020. In India it was recognised on the day (22March,2020)with the declaration of JANATA-CURFEW by our honourable Prime Minister , followed by Lockdown on March 25th, 2020. This was not the end...one day converted into days, days into weeks, weeks into months, months into years.....and now its going to complete almost two years, but its ‘havoc’ is not about to stop yet. No sooner do we try to come back to normal life, than its new variant appears like DELTA and now again another one ---OMICRON. By December 11, 2021, It has affected around 27 crores of people all over the world, total deaths recorded are more than 53 lacs, and in India around 4,75,000 people died of this deadly disease(worldometers.info/coronavirus). Apart from this it has given mental- stress, fear, panic and depressions. Everyone was scared of the fear that any moment off life could be the last one. In the history of mankind it is the first and foremost disease that has persisted for such a long time. Even after vaccination of more than one crores of people, it’s another new variant---OMICRON has knocked at the doors.
