Overview Hantaviruses are transmitted to humans from the dried droppings, urine, or saliva of mice and rats. The capsid is composed of proteins whose folded structure contains five alpha-helices in the N-terminal lobe (5-H motif) and three alpha-helices in the C-terminal lobe (3-H motif). Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE).VEE can affect all equine species, such as horses, donkeys, and zebras.After infection, equines may suddenly die or show progressive central nervous system disorders.
