According to MedlinePlus, the coronavirus disease 2019 (COVID-19), which used to be called the novel coronavirus (2019-nCoV), is a new type of coronavirus. It causes respiratory illness in people. It was first identified in Wuhan, China.
COVID-19 can spread from person to person. This usually happens through respiratory droplets - when someone with the virus coughs or sneezes, and you breathe it in. Most often, you need to be close to the person (within 6 feet) for it to spread this way. It might be possible to get COVID-19 by touching a surface or object that has the virus on it and then touching your own mouth, nose, or possibly your eyes. But this is not thought to be the main way the virus spreads.
People who have been in close contact with someone who is infected are at higher risk. This includes health care workers who care for people with COVID-19.
COVID-19 can cause respiratory illness that ranges from mild to severe or even deadly. The symptoms usually start between 2 to 14 days after you get infected.
According to the World Health Organization (WHO) the name for the disease people experience is coronavirus disease or COVID-19 and the virus itself is called severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2. HIV & AIDS are an example of a virus and the disease it causes.
