According to the World Health Organization (WHO), Coronaviruses are a large family of viruses found in both animals and humans. Some infect people and are known to cause illness ranging from the common cold to more serious respiratory infections like bronchitis, pneumonia or severe acute respiratory syndrome (SARS) or Middle East Respiratory Syndrome (MERS).
The novel coronavirus (CoV) is a new strain of coronavirus that has not been previously identified in humans. The new, or “novel” coronavirus, now called 2019-nCoV or COVID-19, had not been previously detected before the outbreak was reported in Wuhan, China in December 2019. COVID-19 causes severe respiratory infections that spread mainly from person-to-person through close contact, for example, in a household, workplace or healthcare centre.
