Human coronavirus 229E

Human coronavirus 229E (HCoV-229E) is a species of coronavirus which infects humans and bats.[1] The infecting virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor.[2] Along with Human coronavirus OC43, it is one of the viruses responsible for the common cold.[3][4] The species is a member of the genus Alphacoronavirus and subgenus Duvinacovirus.[5][6]

TransmissionEdit

HCoV-229E transmits via droplet-respiration and fomites.

Signs and symptomsEdit

HCoV-229E is associated with a range of respiratory symptoms, ranging from the common cold to high-morbidity outcomes such as pneumonia and bronchiolitis. However, such high morbidity outcomes are always seen in cases with coinfection with other respiratory pathogens with a single reported exception; although infection with 229E alone is almost exclusively associated with asymptomatic or mild disease there is a single published case report to date of a 229E infection that caused acute respiratory distress syndrome (ARDS) in an otherwise healthy patient having no detectable coinfection with another pathogen.[7] HCoV-229E is also among the coronaviruses most frequently codetected with other respiratory viruses, particularly with human respiratory syncytial virus (HRSV).[8][9][10]

EpidemiologyEdit

HCoV-229E is one of the seven human coronaviruses which include HCoV-NL63, HCoV-OC43, HCoV-HKU1 and SARS-CoV-2 and are globally distributed.[11][12] However, the viruses were detected in different parts of the world at different times of the year.[13][14][15]
