Its antigenic shift-sudden changes in Neuraminidase and hemaglutinin
Rota is the only other virus capable of antigenic shift-reassortment of RNA fragments(it has segmented RNA genome).

well i have done this q in q bank, and the ans is rota, but here is my doubt,
well i read somewhere that hiv , the gp120 and gp41, we always have a high igm to that because, the ag keeps on undergoing drift and heb=nce body keeps on mounting antibodies to the new ag, so why not here... i hope u guys got my question??????

I was thinking the same sturge, but now i understand that the q is asking specifically about the organism that possesses
similar "biological attribute" as influenza virus.
So, we can't argue that both influenza and rotaviruses are segmented rna viruses, that undergo reassortment in HA and NA.
