A cluster of cases of pneumonia that occurred in Wuhan, Hubei Province China during December 2019, were confirmed in early January 2020 as caused by a novel coronavirus (SARS-CoV-2). SARS-CoV2 may have originated from an unknown animal source, but is mainly transmitted from human to human by respiratory droplets. National and international spread of this virus has resulted in COVID-19 cases being reported worldwide.
The main symptoms of COVID-19 are recent onset of a new continuous cough and/or a high temperature. Symptoms range from mild to life threatening. Most cases report a mild illness, but some individuals will develop pneumonia causing shortness of breath and breathing difficulties. Those who are elderly or have pre-existing health issues are more likely to develop severe disease.
COVID-19 is transmitted through droplets of saliva or discharge from the nose when an infected person coughs or sneezes and direct or indirect contact with these secretions. In addition to respiratory secretions, other coronaviruses have been detected in blood, faeces and urine.
