Animal Diseases and Biosecurity

​​Rabbit Hemorrhagic Disease Virus, also referred to as RHD or RHDV, is a fatal viral infection in rabbits. RHDV Type 2 (RHDV2) was identified in a feral domestic rabbit colony in the Milwaukie, Oregon area on Tuesday, March 23, 2021. This disease is highly contagious between domestic rabbits and has high mortality rates in rabbit colonies.
Unlike RHDV, RHDV2 can infect native rabbit and hare species.

Symptoms of RHD in domestic rabbits may include:

  • ​Acute/rapid death
  • Fever
  • Lethargy
  • Lack of appetite
  • Congested membranes around the eyes
  • Nervousness
  • Lack of coordination
  • Excitement or paddling
  • Difficulty breathing
  • Bloody, frothy nasal discharge at death


The best way to protect your rabbits is to practice strong biosecurity practices. There is no treatment or cure for RHD and currently there is no vaccine approved for use against the virus in United States. Limited Emergency Use Authorizations have been granted to Oregon Veterinarians to import non-approved vaccine from Europe. Please contact your veterinarian for more information and to inquire if they offer the vaccine.
