That's off wikipedia lol
Coronaviruses are believed to cause 15 to 30% of all common colds in adults and children.
[14] Coronaviruses cause colds with major symptoms, such as
fever and
sore throat from swollen
adenoids, primarily in the winter and early spring seasons.
[27] Coronaviruses can cause
pneumonia – either direct
viral pneumonia or a secondary
bacterial pneumonia – and may cause
bronchitis – either direct viral bronchitis or a secondary bacterial bronchitis.
[28] The much publicized human coronavirus discovered in 2003,
SARS-CoV, which causes
severe acute respiratory syndrome (SARS), has a unique pathogenesis because it causes both
upper and
lower respiratory tract infections.
[28] There are no vaccines or antiviral drugs to prevent or treat human coronavirus infections.
[29]
Seven strains of human coronaviruses are known:
- Human coronavirus 229E (HCoV-229E)
- Human coronavirus OC43 (HCoV-OC43)
- Severe acute respiratory syndrome coronavirus (SARS-CoV)
- Human coronavirus NL63 (HCoV-NL63, New Haven coronavirus)
- Human coronavirus HKU1
- Middle East respiratory syndrome-related coronavirus (MERS-CoV), previously known as novel coronavirus 2012 and HCoV-EMC
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), previously known as 2019-nCoV or "novel coronavirus 2019"
The coronaviruses HCoV-229E, -NL63, -OC43, and -HKU1 continually circulate in the human population and cause respiratory infections in adults and children world-wide.

The name "coronavirus" is derived from the Latin corona and the Greek κορώνη (korṓnē, "garland, wreath"), meaning crown or halo. The name refers to the characteristic appearance of virions (the infective form of the virus) by electron microscopy, which have a fringe of large, bulbous surface projections creating an image reminiscent of a crown or of a solar corona. This morphology is created by the viral spike (S) peplomers, which are proteins on the surface of the virus that determine host tropism.
So by the looks of it it's been around since 2003
