Fuluwenza B Virus Nucleic Acid

Kachilombo ka fuluwenza, mtundu woyimira wa Orthomyxoviridae, ndi kachilombo komwe kamayambitsa matenda omwe amaika pachiwopsezo thanzi la anthu ndipo kamatha kufalikira kwambiri kwa anthu omwe ali ndi kachilomboka. Miliri ya fuluwenza ya nyengo imakhudza anthu pafupifupi 600 miliyoni padziko lonse lapansi ndipo imayambitsa imfa pakati pa 250,000 ndi 500,000 chaka chilichonse, ndipo kachilombo ka fuluwenza B ndi chimodzi mwa zifukwa zazikulu.^[1]Kachilombo ka Fluunza B, komwe kamadziwikanso kuti IVB, ndi RNA yokhala ndi stranded negative-stranded single-stranded. Malinga ndi nucleus sequence ya dera lake la HA1 lodziwika bwino la antigen, kakhoza kugawidwa m'magulu awiri akuluakulu, mitundu yoyimira ndi B/Yamagata/16/88 ndi B/Victoria /2/87(5)^[2]Kachilombo ka Fluenza B nthawi zambiri kamakhala ndi kachilombo kamene kamayambitsa matenda. Zapezeka kuti IVB imatha kupatsira anthu ndi nyama za m'madzi zokha, ndipo nthawi zambiri simayambitsa mliri wapadziko lonse lapansi, koma ingayambitse miliri ya nyengo m'madera osiyanasiyana.^[3]Kachilombo ka fuluwenza B kamafalikira kudzera m'njira zosiyanasiyana monga m'mimba, m'mapapo, kuwonongeka kwa khungu ndi conjunctiva. Zizindikiro zake makamaka ndi kutentha thupi kwambiri, chifuwa, mphuno yotuluka madzi, myalgia, ndi zina zotero. Zambiri mwa izo zimayenderana ndi chibayo chachikulu, matenda oopsa a mtima. Pa milandu yoopsa, kulephera kwa mtima, impso ndi ziwalo zina kumabweretsa imfa, ndipo chiwerengero cha imfa chimakhala chachikulu kwambiri.^[4]Chifukwa chake, pakufunika njira yosavuta, yolondola komanso yachangu yodziwira kachilombo ka chimfine B, komwe kungapereke chitsogozo cha mankhwala azachipatala komanso kuzindikira matenda.
