Huaketo Rewharewha B Waikawa Karihi

Ko te huaketo rewharewha, he momo māngai nō Orthomyxoviridae, he mate e tino mōrearea ana ki te hauora o te tangata, ā, ka taea te horapa whānuitia te mate.

E ai ki te raupapa nucleotide o tōna rohe HA1 āhuatanga antigenic, ka taea te wehewehe ki ngā whakapapa matua e rua, ko ngā momo matua ko B/Yamagata/16/88 me B/Victoria /2/87(5)^[2]He kaha te kaha o te huaketo rewharewha B ki te noho hei kaiāwhina. Kua kitea ko te IVB anake ka pangia e te tangata me ngā kekeno, ā, kāore e puta he mate urutā puta noa i te ao, engari ka taea e ia te whakaputa mate urutā ā-rohe.^[3]Ka taea te hora i te huaketo rewharewha B mā roto i ngā huarahi maha pērā i te ara nakunaku, te ara manawa, te kino o te kiri me te kanohi kanapa. Ko ngā tohu ko te kirika nui, te mare, te ihu pupuhi, te mamae o te uaua, me ētahi atu. Ko te nuinga o ēnei ka haere tahi me te niumōnia kino, te mate ngakau kino.
