Virusi ya Grippe B iterwa n'aside nucleic

Virusi ya Grippe, ubwoko bw’ubwoko bwa Orthomyxoviridae, ni indwara itera indwara ibangamira ubuzima bw’abantu cyane kandi ishobora kwanduza abantu benshi. Icyorezo cya Grippe cy’ibihe by’imvura cyanduza abantu bagera kuri miliyoni 600 ku isi yose kandi gitera impfu hagati ya 250.000 na 500.000 buri mwaka, muri zo virusi ya Grippe B ikaba imwe mu mpamvu zikomeye.^[1]Virusi ya Grippe B, izwi kandi nka IVB, ni RNA ifite umugozi umwe gusa. Dukurikije urukurikirane rwa nucleotide rw'agace kayo ka antigenic HA1, ishobora kugabanywamo ubwoko bubiri bw'ingenzi, ubwoko buyihagarariye ni B/Yamagata/16/88 na B/Victoria /2/87(5)^[2]Virusi ya Grippe B muri rusange ifite umwihariko ukomeye w’umuntu uyirwaye. Byagaragaye ko IVB ishobora kwanduza abantu n’inyamaswa zo mu bwoko bwa seal gusa, kandi muri rusange ntabwo itera icyorezo ku isi yose, ahubwo ishobora gutera icyorezo cyo mu turere dutandukanye.^[3]Virusi ya Grippe B ishobora kwandurira mu nzira zitandukanye nko mu nzira y'igogora, mu nzira z'ubuhumekero, kwangirika k'uruhu no mu nda. Ibimenyetso ni umuriro mwinshi, inkorora, izuru riva, indwara ya myalgia, nibindi. Ibyinshi muri byo biherekezwa n'umusonga ukomeye, indwara ikomeye y'umutima. Mu bihe bikomeye, umutima, impyiko n'izindi ngingo zikora nabi biganisha ku rupfu, kandi igipimo cy'impfu kiba kiri hejuru cyane.^[4]Bityo rero, hakenewe byihutirwa uburyo bworoshye, bunoze kandi bwihuse bwo gupima virusi ya grippe B, bushobora gutanga ubuyobozi ku miti no gusuzuma indwara.
