Imbuto zisanzwe twateye muri iryo gerageza indwara zaraziriye zarazimaze ariko izongerewe ubushobozi zihagaze neza.'
Ubusahakshatsi nk'ubu kandi bumaze imyaka ine bugererezwa ku gihingwa cy'imyumbati mu mirima ya RAB iri Rubona mu Karere ka Huye.
Ni imbuto y'imyumbati ishobora kwihanganira indwara izwi nka kabore yibasira imyumbati ndetse ubu icyiciro gikurikiyeho ni ukuyiha abaturage bagatangira kuyihinga.
