Following the identification of a cluster of pneumonia cases in Wuhan, Hubei Province of Cina, Chinese authorities reported on the 17th January 2020 that the disease was caused by a virus which has not previously been identified in humans. This novel virus is called COVID-19. This is not the first time we have a coronavirus outbreak. In 2003, a new coronavirus emerged leading to the Severe Acute Respiratory Syndrome (SARS) outbreak. In 2012, the Middle East Respiratory Syndrome (MERS) was caused by a coronavirus associated with transmission from camels.
Most people who become infected experience mild illness and recover but it can be more severe for others.
