,,Korona virus" haqida maqola.

''-Ushbu maqola viruslar guruhi haqida. COVID-19 pandemiyasi bilan bog'liq kasallik. Ushbu kasallikni keltirib chiqaradigan virusni ko'rish uchun Og'ir o'tkir respirator sindromli korona virus.''

Koronaviruslar sutemizuvchilar va qushlardan kasalliklarni keltirib chiqaradigan RNK viruslari guruhi. Odamlar va qushlarda ular nafas yo'llari infektsiyasini keltirib chiqaradi. Bu o'limga olib kelishi mumkin. Odamlardagi yengil kasalliklar orasida shamollashning ba'zi holatlari (bu boshqa viruslar, asosan rinoviruslar tomonidan ham yuzaga keladi), ko'proq halokatli navlar esa davom etayotgan pandemiyaga sabab bo'lgan SARS, MERS va COVID-19 ni keltirib chiqarishi mumkin. Sigirlar va cho'chqalarda ular diareya, sichqonlarda esa gepatit va ensefalomielitni keltirib chiqaradi.

Koronaviruslar Orthocoronavirinae kichik oilasi, Coronaviridae oilasida Nidovirales va Riboviria tashkil qiladi.[3][4] Ular musbat ma'noli bir zanjirli RNK genomiga va spiral simmetriyadagi nukleokapsidga ega bo'lgan o'ralgan viruslardir.[5] Koronaviruslarning genom hajmi taxminan 26 dan 32 kilobazagacha o'zgarib turadi, bu RNK viruslari orasida eng kattasidan biridir.[6] Ularning sirtidan chiqadigan o'ziga xos to'rsimon shpiklari bor, ular elektron mikrograflarda quyosh tojini eslatuvchi tasvirni yaratadilar, ularning nomi esa shundan kelib chiqadi.[7]

Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS and COVID-19, which is causing an ongoing pandemic. In cows and pigs they cause diarrhea, while in mice they cause hepatitis and encephalomyelitis.

Coronaviruses constitute the subfami a positive-sense single-stranded RNA genomely Orthocoronavirinae, in the family Coronaviridae, order Nidovirales and realm Riboviria.[3][4] They are enveloped viruses  with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. [5] The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, one of the largest among RNA viruses. [6] They have characteristic club-shaped spikes that project from their surface, which in electron micrographs create an image reminiscent of the solar corona, from which their name derives.[7]
