Furuwenza B Virus Nucleic Acid

Utachiona hwefuruwenza, rudzi rweOrthomyxoviridae, ihutachiona hunotyisidzira hutano hwevanhu zvakanyanya uye hunogona kutapurira vanhu vakawanda. Mafuruwenza emwaka anotapurira vanhu vanosvika mamiriyoni mazana matanhatu pasi rose uye anokonzera kufa kwevanhu vanosvika 250,000 kusvika 500,000 gore rega rega, uye hutachiona hwefuruwenza B ndeimwe yezvikonzero zvikuru.^[1]. Utachiona hwefuruwenza B, hunozivikanwawo seIVB, iRNA ine tambo imwe chete isina tambo. Zvichienderana nehurongwa hwenucleotide hwenzvimbo yayo yeHA1 ine antigen, hunogona kukamurwa kuita madzinza maviri makuru, marudzi anomiririra ndeaya: B/Yamagata/16/88 uye B/Victoria /2/87(5).^[2]. Virusi refuruwenza B rinowanzova nehutachiona hwakasiyana-siyana. Zvakaonekwa kuti IVB inogona kutapurira vanhu nemhuka dzemugungwa chete, uye kazhinji haikonzeri denda repasi rose, asi inogona kukonzera denda remwaka munharaunda.^[3]. Utachiona hwefuruwenza B hunogona kutapuriranwa nenzira dzakasiyana siyana dzakadai senzira yekugaya chikafu, nzira yekufema, kukuvara kweganda uye conjunctiva. Zviratidzo zvacho zvinonyanya kuva fivha yakanyanya, kukosora, mhino inoyerera, myalgia, nezvimwewo. Zvizhinji zvacho zvinoperekedzwa nemabayo akanyanya, kurwara kwemoyo kwakanyanya. Muzviitiko zvakakomba, kutadza kwemoyo, itsvo nedzimwe nhengo dzemuviri kunotungamira kurufu, uye mwero werufu wakakwira kwazvo.^[4]Saka, pane chikonzero chikuru chekutsvaga nzira iri nyore, yakarurama uye inokurumidza yekuona hutachiona hwefuruwenza B, iyo inogona kupa gwara rekurapa uye kuongororwa kwechirwere.
