Clinical Effects

Epidemiology

Habitat

  • RECV has been observed in feces of clinically healthy adult rabbits.

Lifecycle

  • Inapparent or persistent infections may occur   →   virus maintenance.
  • RECV - experimentally infected rabbits have been reported to shed virus for up to 29 days in feces.

Transmission

  • RECV - fecal-oral, highly contagious.
  • RbCV - experimental infection of RbCV achieved via intramuscular inoculation, natural route not described.

Control

Control via chemotherapies

  • Treat dehydration and supply electrolytes.

Control via environment

  • Attention to hygiene.
  • Avoid poor management conditions, eg overcrowding or stress.
  • Isolate infected individuals.

Vaccination

  • None available.
