Ibicurane B virusi Nucleic Acide

Virusi y'ibicurane, ubwoko bwa Orthomyxoviridae ihagarariye, ni indwara yangiza ubuzima bw'abantu kandi ishobora kwanduza cyane abayakira. Ibicurane by'ibicurane ibihe byanduza abantu bagera kuri miriyoni 600 ku isi kandi bigatera abantu 250.000 kugeza 500.000 buri mwaka, muri byo virusi ya grippe B ni imwe mu mpamvu zitera^[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 imirongo ibiri yingenzi, 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 na kashe gusa, kandi muri rusange ntabwo itera icyorezo ku isi yose, ariko irashobora gutera icyorezo cyibihe byo mukarere.^[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.
