During a blood meal, [[Culicidae|mosquito]] vectors transmit viral particles between wild animal hosts.  Viruses that are able to penetrate the mosquito's gut can pass via the haemolymph to the oral glands.  Here, viral replication is followed by the shedding of viral particles into the saliva and other oral secretions.  Viral multiplication may not be necessary for transmission if the original blood meal contained sufficient numbers of viral particles.  It is thought that the mosquito remains permanently infected.<ref name="multiple">Bertone, J.J (2010) Viral Encephalitis in Reed, S.M, Bayly, W.M. and Sellon, D.C (2010) '''Equine Internal Medicine''' (Third Edition), ''Saunders'', Chapter 12</ref>.
