|q8=What is the epidemiology of ''Blue eye disease''?
|a8=In the first third of gestation:
+
|a8=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.
