Aia nā coronaviruses hou i ka genus p.COVID-19he ma'i lele hanu. Hiki ke maʻalahi nā kānaka. I kēia manawa, ʻo nā maʻi i loaʻa i ka coronavirus novel ke kumu nui o ka maʻi; ʻO ka poʻe i hoʻopaʻa ʻia asymptomatic hiki ke lilo i kumu maʻi. Ma muli o ka noiʻi epidemiological o kēia manawa, ʻo ka manawa incubation he 1 a 14 mau lā, ʻo ka hapa nui he 3 a 7 mau lā. ʻO nā hōʻike nui e pili ana i ke kuni, ka luhi a me ka ʻū maloʻo. Loaʻa ka nasal congestion, runny ihu, ʻeha ʻāʻī, myalgia a me ka maʻi maʻi i kekahi mau hihia.

Ke hoʻopili nei ka maʻi SARS-CoV2 i kahi kino, ʻo RNA, ka mea genetic o ka maʻi, ʻo ia ka māka mua e ʻike ʻia. ʻO ke ʻano o ka viral load profile o SARS-CoV-2 e like me ka influenze, e piʻi ana i ka manawa o ka hoʻomaka ʻana o nā hōʻailona, ​​​​a laila hoʻomaka e emi. Me ka hoʻomohala ʻana o ka papa maʻi ma hope o ka maʻi maʻi, e hoʻopuka ka ʻōnaehana pale kanaka i nā antibodies, ma waena o ka IgM ka antibody mua i hana ʻia e ke kino ma hope o ka maʻi, e hōʻike ana i ka pae koʻikoʻi o ka maʻi. Hiki ke ʻike ʻia nā antibodies IgG i SARS-CoV2 ma hope o ka maʻi. Hiki ke loaʻa nā hopena maikaʻi no ka IgG a me ka IgM ma hope o ka maʻi a hiki ke hōʻike i ka maʻi koʻikoʻi a i ʻole ka maʻi hou. Hōʻike ka IgG i ka manawa hoʻomaha o ka maʻi a i ʻole ka mōʻaukala o ka maʻi i hala.

Eia nō naʻe, loaʻa i ka IgM a me IgG ka manawa puka makani mai ka maʻi maʻi a hiki i ka hana antibody, ʻaneʻane ʻike ʻia ka IgM ma hope o ka hoʻomaka ʻana o ka maʻi i kekahi mau lā, no laila ke waiho pinepine nei ko lākou ʻike ʻana ma hope o ka ʻike ʻana i ka waikawa nucleic a ʻoi aku ka liʻiliʻi ma mua o ka ʻike waika nucleic. I nā hihia i maikaʻi ʻole ai nā hoʻokolohua nucleic acid amplification a aia kahi loulou epidemiological ikaika i ka maʻi COVID-19, hiki i nā laʻana serum paired (i ka manawa acute a convalescent) ke kākoʻo i ka maʻi maʻi.

KUMU

ʻO COVID-19 IgG/IgM ka pahu hoʻāʻo wikiwiki(WB/S/P) kahi immunoassay e pili ana i ka membrane qualitative no ka ʻike ʻana i nā antibodies (IgG a me IgM) i ka Novel coronavirus i loko o ke koko holoʻokoʻa o ke kanaka / Serum / plasma. Aia ka pahu ho'āʻo：1) kahi pad coiyugate kala burgundy i loaʻa i ka Novel coronavirus recombinant envelopp antigens coi^ugated me Colloid gula (Novel coronavirus c两ugates), 2) kahi ʻāpana membrane nitrocellulose i loaʻa nā laina hoʻāʻo ʻelua (laina IgG a me IgM) a me kahi laina mana (laina C). Ua uhi mua ʻia ka laina IgM me ka antibody IgM anti-Human Mouse, ua uhi ʻia ka laina IgG Mouse anti-Human IgG antibody, i ka wā e hāʻawi ʻia ai ka nui o nā mea hoʻohālike i loko o ka luawai laʻana o ka cassette hoʻāʻo. Ke neʻe nei ka specimen ma ka hana capillary ma o ka cassette. ʻO ka IgM anti-Novel coronavirus, inā aia i loko o ka specimen, e hoʻopaʻa i ka Novel coronavirus coiyugates. A laila hopu ʻia ka immunocomplex e ka reagent i uhi mua ʻia ma ka band IgM, e hana ana i kahi laina IgM kala burgundy, e hōʻike ana i kahi hopena hōʻike maikaʻi o ka Novel coronavirus IgM. ʻO ka IgG anti-Novel coronavirus i loaʻa i ka specimen e hoʻopaʻa i nā conjugates Novel coronavirus. A laila hopu ʻia ka immunocomplex e ka reagent i uhi ʻia ma ka laina IgG, e hana ana i kahi laina IgG kala burgundy, e hōʻike ana i kahi hopena hōʻike maikaʻi o ka Novel coronavirus IgG. ʻO ka nele o nā laina T (IgG a me IgM) e hōʻike ana i kahi
