Overview
Coronavirus, named due to the "crown" like the appearance of its surface projections, was first isolated from chickens in 1937. The etiological agent, a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), named for the similarity of its symptoms to those induced by the severe acute respiratory syndrome, causing coronavirus disease 2019 (COVID-19), is a virus identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China.
Historical Perspective
- Coronavirus, named due to the "crown" like the appearance of its surface projections, was first isolated from chickens in 1937.,
- In 1965, Tyrrell and Bynoe used cultures of human ciliated embryonal trachea to propagate the first human coronavirus (HCoV) in vitro.
- There are now approximately 15 species in this family, which infect not only humans but cattle, pigs, rodents, cats, dogs and birds (some are serious veterinary pathogens, especially chickens).
- The etiological agent, a novel coronavirus, SARS-CoV-2, named for the similarity of its symptoms to those induced by the severe acute respiratory syndrome, causing coronavirus disease 2019 (COVID-19), is a virus identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China.[1][2]
- Initially, the patients were believed to have contracted the virus from seafood/animal markets which suggested animal-to-human spread.
- The growing number of patients however, suggest that human-to-human transmission is actively occurring.[3][4]
- The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020.
- On March 12, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic.
