CHIDULE

Coronaviruses ndi a Nidovirales, Coronaviridae ndi Coronavirus Gulu lalikulu la ma virus omwe amapezeka kwambiri m'chilengedwe. The 5 'mapeto a ma virus gulu ali A methylated kapu kapangidwe, ndi 3' mapeto ali A poly (A) mchira, genome anali 27-32kb yaitali. Ndilo kachilombo ka RNA kakang'ono kodziwika kwambiri komwe kamakhala ndi ma genome.Coronaviruses amagawidwa m'magulu atatu: α,β, γ.α,β kokha tizilombo toyambitsa matenda, γ ndizomwe zimayambitsa matenda a mbalame. CoV idawonetsedwanso kuti imafalikira makamaka kudzera munjira yachindunji kapena kudzera mu ma aerosol ndi madontho, ndipo zawonetsedwa kuti zimafalikira kudzera munjira yapakamwa. Ma Coronaviruses amalumikizidwa ndi matenda osiyanasiyana mwa anthu ndi nyama, zomwe zimayambitsa matenda a kupuma, kugaya chakudya komanso kwamanjenje mwa anthu ndi nyama. SARS-CoV-2 ndi ya β coronavirus, yomwe imakutidwa, ndipo tinthu tating'onoting'ono tozungulira kapena tozungulira, nthawi zambiri timakhala tating'onoting'ono, tokhala ndi mainchesi a 60 ~ 140nm, ndipo mawonekedwe ake ndi osiyana kwambiri ndi a SARSr-CoV ndi MERSr- Mawonetseredwe azachipatala a CoV ndi malungo, kutopa ndi zizindikiro zina zokhazikika, zomwe zimatsagana ndi chifuwa chowuma, dyspnea, etc., zomwe zimatha kukhala zovuta kwambiri. chibayo, kulephera kupuma, kupuma movutikira kwambiri, kugwedezeka kwamadzi, kulephera kwa ziwalo zambiri, kusokonezeka kwa metabolic acid, komanso kuyika moyo pachiwopsezo. Kupatsirana kwa SARS-CoV-2 kudadziwika makamaka kudzera m'malovu opumira (kuyetsemula, kutsokomola, ndi zina) komanso kukhudzana (kutola mphuno, kusisita m'maso, ndi zina). Kachilombo kameneka kamakhudzidwa ndi kuwala kwa ultraviolet ndi kutentha, ndipo imatha kutsekedwa bwino ndi 56 ℃ kwa mphindi 30 kapena zosungunulira zamadzimadzi monga ethyl ether, 75% ethanol, mankhwala ophera tizilombo ta chlorine, peroxyacetic acid ndi chloroform.
