The disease is '''self limiting''' and closed herds will have sporadic outbreaks of the disease once a herd is infected. The virus can be found in the '''axon of neurons''' from its original site of replication, which is thought to be the '''nasal mucosa and tonsils'''.  It is also found  in tissues such as lung, liver, spleen, kidney, lymph node, heart and testis; suggesting that the virus is spread hematogenously.

The disease is '''self limiting''' and closed herds will have sporadic outbreaks of the disease once a herd is infected.  There is '''no approved vaccine''' for the control of blue eye disease but killed-virus vaccine has been shown to be effective <ref name="Stephano et al., 1992"> Stephano, H.A., Olvera, M.J., Garcia, V.P., Ramirez, M.H., Cordoba, D.J.

Eliminating blue eye disease from affected herds can be achieved by '''closing the herd, running an all-in/all-out systems''', and following good '''washing and disinfecting protocols'''.
