The Human Coronavirus 229E (HCov-229E) was first identified in 1967 belongs to the alpha-coronavirus sub family. 

Like other members of the coronavirus family, it infects the upper respiratory tract and causes symptoms that are commonly associated with the flu. It can cause more severe problems in immunocompromised individuals. 

Prior to the Covid-19 pandemic, the HCov-229E accounted for the second most common coronavirus infections after OC-43. 

Compared to other members of the coronavirus family, 229E shows very little genetic variation even when isolated from distinct geographical locations.

The comparatively smaller genetic variation makes anti-viral test results more reliable with the HCov-229E.
