Ibicurane B virusi Nucleic Acide

Virusi y'ibicurane, ubwoko bwa Orthomyxoviridae ihagarariye, ni indwara yangiza ubuzima bw'abantu kandi ishobora kwanduza cyane abayakira.Icyorezo cya grippe ibihe byanduza abantu bagera kuri miriyoni 600 kwisi yose kandi gitera impfu 250.000 kugeza 500.000 buri mwaka, muri zo virusi ya grippe B nimwe mubitera^[1].Virusi y'ibicurane B, izwi kandi ku izina rya IVB, ni RNA imwe ihagaze nabi.Ukurikije nucleotide ikurikirana ya antigenic iranga akarere ka HA1, irashobora kugabanywamo ibice bibiri byingenzi, imirongo ihagarariye ni B / Yamagata / 16/88 na B / Victoria / 2/87 (5)^[2].Virusi ya grippe B muri rusange ifite umwihariko wo kwakira abashyitsi.Byagaragaye ko IVB ishobora kwanduza abantu gusa na kashe, kandi muri rusange ntabwo itera icyorezo ku isi, ariko irashobora gutera icyorezo cy’ibihe mu karere^[3].Virusi y'ibicurane B irashobora kwanduzwa binyuze mu nzira zitandukanye nk'inzira zifungura, inzira z'ubuhumekero, kwangiza uruhu na conjunctiva.Ibimenyetso ahanini ni umuriro mwinshi, inkorora, izuru ritemba, myalgia, nibindi. Byinshi muribi biherekejwe numusonga ukabije, umutima utera.Mubihe bikomeye, umutima, impyiko nizindi ngingo zananiranye zitera urupfu, kandi abapfa ni benshi cyane^[4].Niyo mpamvu, hakenewe byihutirwa uburyo bworoshye, bwuzuye kandi bwihuse bwo kumenya virusi ya grippe B, ishobora gutanga ubuyobozi kumiti ivura no gusuzuma.
