👉Corona virus comprises of a large family of viruses that are common in human beings as well animals (camels, cattle, cats, and bats).

👉There are seven different strains of corona virus:

  • 229E (alpha coronavirus)
  • NL63 (alpha coronavirus)
  • OC43 (beta coronavirus)
  • HKU1 (beta coronavirus)
  • MERS-CoV (the beta coronavirus that causes Middle East Respiratory Syndrome, or MERS)
  • SARS-CoV (the beta coronavirus that causes severe acute respiratory syndrome, or SARS)
  • SARS-CoV-2 (the novel coronavirus that causes coronavirus disease 2019, or COVID-19)

👉Sometimes corona virus from animals infect people and spread further via human to human transmission such as with MERS-CoV, SARS-CoV, and now with this COVID 19 (Corona disease 2019).

👉The virus that causes COVID-19 is designated severe acute respiratory syndrome corona virus 2 (SARS-CoV-2); previously, referred to as 2019-nCoV.

👉Towards December 2019, this novel corona virus was identified as a cause of upper and lower respiratory tract infections in Wuhan, a city in the Hubei Province of China.

👉It rapidly spread, resulting in an epidemic throughout China and then gradually spreading to other parts of the world in pandemic proportions.

👉It has affected almost every continent in this world, except Antarctica.

👉In February 2020, the World Health Organization designated the disease COVID-19, which stands for corona virus disease 2019.
