Covid or Covid-19 is an abbreviation for Coronavirus disease 2019. This is the name of the disease and is named after the year it was discovered.
The actual virus is called SARS-CoV-2, which is short for Severe Acute Respiratory Syndrome coronavirus 2. The 2 is because we have already had Severe Acute Respiratory Syndrome coronavirus 1 or SARS-CoV-1, this is the virus that cased what is known as the SARS outbreak a number of years ago.
SARS-CoV-2 was first found in the Wuhan area of China in 2019, but this is only where it was first found, it likely developed somewhere else and only infected humans there.
