Koronavirus[1] atawa coronavirus (istilah takanalnya: virus korona, virus corona, atawa virus Corona) adalah sagarumbungan pirus matan subpamili Orthocoronavirinae dalam kulawarga Coronaviridae wan urdu Nidovirales.[2][3] Kalumpuk pirus ngini nang kawa maulah panyakit lawan burung wan mamalia (tamasuk manusia).[4] Pada manusia, koronavirus maulah panjangkitan saluran pahinakan nang rancaknya kada parah, nang kaya salismaan, saupama sapalih tawas panyakit kaya babarapa SARS, MERS, wan COVID-19 sipatnya labih mamati'i. Manipistasi kalinis nang timbul bamacam-macam pada sapasias nang lain: pada hayam, koronavirus maulah panyakit saluran pahinakan atas, amun sapi wan babi maulah bahiraan.
Koronavirus adalah pirus basalubung lawan ginum RNA utas tunggal plus wan nukleokapsid batawas hiliks simitris. Jumlah ginum koronavirus kikira antara 27–34 kilu pasangan basa, pangganalnya di antara virus RNA nang dikatahuani.[5] Ngaran koronavirus babibit matan basa Latin corona nang baarti mahkuta, nang marujuk lawan ampaian partikal pirus (virion): pirus ngini baisi pinggiran nang maingatakan lawan mahkuta atawa kuruna matahari.
Panamuan
[babak | babak asal-mulanya]Koronavirus ditamu'akan pas 1960-an.[6] Virus nang paling pamulaan ditamui adalah virus bronkitis infeksius pada ayam wan dua virus dari rongga hidung manusia lawan flu biasa nang kenanya dibari ngaran human coronavirus 229E wan human coronavirus OC43.[7] Imbah nnag itu, anggota koronavirus nang lain mulai diidentifikasi, tamasuk SARS-CoV pas 2003, HCoV NL63 paa 2004, HKU1 pas 2005, MERS-CoV (panambayannya dikanal sabagai 2012-nCoV) pas 2012, dan SARS-CoV-2 (panambayannya dikanal sabagai 2019-nCoV) pas 2019; sapalih dari virus-virus ini kabanyakan takait lawan infeksi saluran pahinakan nang sarius.
Nama wan morfologi
[babak | babak asal-mulanya]Nama koronavirus ba'asal matan basa Latin corona aan bahasa Yunani κορώνη (korṓnē, "lingkaran, untaian"), nang ba'arti mahkota atawa lingkaran cahaya. Namanya ba'acuan lawan panampilan karakteristik virion (bantuk infektif virus) dalam mikroskop elektron, nang memproyeksikan pinggiran parmukaan virus nang ganal wan bulat nang mahasil'akan gambar nang maingatakan lawan mahkota atau korona matahari. Morfologi ngiini diulah oleh peplomer tonjolan protein permukaan virus (S), nang manantu'akan tropisme inang.
Protein nang manyusun struktur koronavirus yaitu protein tonjolan (spike) (S), amplop (E), membran (M), wan nukleokapsid (N). Khusus pada virus SARS, andak pangikatan reseptor pada protein S memediasi perlekatan virus ke reseptor sel inangnya yaitu, enzim pengubah angiotensin (ACE2).[8] Sapalih koronavirus (khususnya anggota Betacoronavirus garis katurunan A) baisi jua tonjolan protein pendek nang dingarani hemaglutinin esterase (HE).[2]
Panularan
[babak | babak asal-mulanya]Panularan koronavirus dari manusia ke manusia diparkirakan tajadi malalui tatamuan langsung dalam jarak nang paraka lewat tetesan kihit atawa percikan (droplet) matan saluran pahinakan nang dihasilakan panderita haratan wahin wan batuk.[9]
Taksonomi

Koronavirus manusia
[babak | babak asal-mulanya]Koronavirus diyakini maulah 15-30% matan samunyaan salismaan urang tuha wan kakanakan.[13] Koronavirus meayababkan salismaan lawan gajala utama nang kaya panas awak wan sakit tanggorokan gara-gara pambangkakan adenoid, tautama pas musim dingin wan pamulaan musim semi.[14] Koronavirus kawa manyababkan pneumonia, baik pneumonia virus langsung atawa pneumonia bakterial sekunder, dan dapat menyebabkan bronkitis, baik bronkitis virus langsung atawa bronkitis bakterial sekunder.[15] Koronavirus manusia nang ditamu'akan paa tahun 2003, SARS-CoV, nang maulah sindrom ngalih banar bahinak (SARS), baisi patogenesis nang unik karena manyababkan infeksi saluran pernapasan bagian atas wan bawah. Balum ada vaksin atawa obat antivirus gasan mancagah atawa maobati infeksi koronavirus manusia.[16]
Tujuh jenis koronavirus manusia nang wayah ini dikatahui:
- Human coronavirus 229E (HCoV-229E)
- Human coronavirus OC43 (HCoV-OC43)
- Koronavirus sindrom pernapasan akut berat (SARS-CoV)
- Human coronavirus NL63 (HCoV-NL63, New Haven coronavirus)
- Human coronavirus HKU1
- Koronavirus terkait sindrom pernafasan Timur Tengah (MERS-CoV), nang panambayannya dikenal sabagai novel coronavirus 2012 dan HCoV-EMC
- Koronavirus sindrom pernapasan akut berat 2 (SARS-CoV-2), panambayannya dikenal sabagai 2019-nCoV atawa "novel coronavirus 2019"
Koronavirus HCoV-229E, -NL63, -OC43, wan -HKU1 batambah tarus dalam populasi manusia aan manyababkan infeksi pahinakan apda urang tuha wan kakanakan di samunyaan dunia.[17]

| Wabah | Jenis virus | Kematian |
|---|---|---|
| Wabah SARS 2003 | SARS-CoV | 774[18] |
| Wabah MERS 2012 | MERS-CoV | Lebih dari 400[19] |

Infeksi pada binatang
[babak | babak asal-mulanya]Koronavirus sudah dipinandui wan dikatahui jadi panyabab kondisi patologi di kedokteran hewan mulai matan tahun 1930. Buhannya mainfiksi bamacam binatang tamasuk babi, sapi, kuda, unta, kucing, anjing, tikus, burung wan kalalawar.[21] Kabanyakannya binatang nang kana koronavirus tainfeksi di Saluran panagukan wan manyabar muntung lawan tahi.[22] Panalitian nang ada labih fokus gasan manjalasakan Patogen Vital nang ada dalam binatang nang takana koronavirus, apalagi virologis nanag tatarik lawan kaduktiran lawan panyakit nang ada di binatang.[23]
