History of Coronavirus

In 2003, a new coronavirus emerged leading to the SARS (severe acute respiratory syndrome) outbreak. In 2012, the Middle East respiratory syndrome (MERS) was found to be caused by a coronavirus associated with transmission from camels. Now Following the identification of a cluster of pneumonia cases in Wuhan, Hubei Province of China, Chinese authorities reported on 7 January 2020 that the causative pathogen was identified as a novel coronavirus (2019-nCoV). These new coronaviruses have RNA sequences that are very similar to coronaviruses from animals. Coronaviruses differences:

• MERS-CoV= camel coronavirus
• SARS = bat coronavirus
• The animal source of COVID-19 has not been identified but is thought to be bats,
