No ka coronavirus o coronaviridae o Nidovirales i ka hoʻonohonoho ʻōnaehana.ʻO nā Coronaviruses nā maʻi RNA me ka envelop a me ka laina laina laina laina maikaʻi strand genome.He ʻano nui lākou o nā maʻi maʻi e kū nei ma ke ʻano.
He anawaena o Coronavirus ma kahi o 80 ~ 120 nm, he methylated cap structure ma ka 5 'hope o ka genome a me ka poly (a) huelo ma ka hope 3'.ʻO ka lōʻihi o ka genome ma kahi o 27-32 KB.ʻO ia ka maʻi maʻi nui loa i nā maʻi RNA i ʻike ʻia.
Hoʻopilikia wale ʻo Coronavirus i nā vertebrates, e like me ke kanaka, ka ʻiole, ka puaʻa, nā pōpoki, nā ʻīlio, nā ʻīlio, nā moa, nā pipi a me nā moa.
Ua hoʻokaʻawale mua ʻia ʻo Coronavirus mai nā moa i ka makahiki 1937. ʻO ke anawaena o nā ʻāpana virus he 60 ~ 200 nm, me ka awelika anawaena o 100 nm.He poepoe a oval paha a he pleomorphism.He envelop ka virus, a aia nā kaʻina spinous ma ka envelop.ʻO ka maʻi āpau e like me ka corona.ʻOkoʻa nā kaʻina hana spinous o nā coronaviruses like ʻole.Hiki ke ʻike ʻia nā kino hoʻohui tubular i kekahi manawa i nā cell i hoʻopili ʻia i ka coronavirus.
ʻO ka 2019 novel coronavirus (2019 ncov, kumu coronavirus pneumonia covid-19) ʻo ia ka hiku o ka coronavirus i ʻike ʻia e hiki ke hoʻopili i nā kānaka.ʻO nā ʻeono ʻē aʻe he hcov-229e, hcov-oc43, HCoV-NL63, hcov-hku1, SARS CoV (ke kumu o ka maʻi hanu acute nui) a me ka mers cov (ke kumu o ka Middle East respiratory syndrome).
