Rabbit Hemorrhagic Disease Virus 2

RHDV2 is a highly contagious and deadly rabbit disease that infects wild and domestic rabbits, hares, and related species, spreading across the U.S. It cannot be transmitted to people or other domestic animals. The mortality rate for the RHDV2 variant in the U.S. is approximately 90%. There is no treatment for RHDV2. Fortunately, there are steps rabbit caretakers can take to prevent its transmission.

The best way to protect your rabbits from RHDV2 is through a combination of yearly vaccination, indoor housing, and biosecurity measures.** Of these, the most effective protection is the vaccination. Here's a handout you can print and share with other rabbit caretakers. rhdv.pdf

Here is a map showing RHDV2 cases in the U.S. as of January 2024:

Scroll to the bottom of the page for a list of veterinarians in the Los Angeles area who have ordered vaccine. Please note that RHDV2 vaccinations are ANNUAL. If you adopted from us, the vaccinations are a requirement per your adoption contract.

Here are some things you can do to help protect your rabbits from the virus:

  • Keep your rabbits indoors 100% of the time. If your rabbits are not indoors now, it's time to consider moving them inside.
  • Do not wear your outside shoes in the home. Practice keeping shoes outside if you don't normally do this, and set aside "indoor" footwear.
  • Avoid contact with rabbits or hares outside the home. Plan what to do if you volunteer at an animal shelter, or have friends with rabbits you watch or visit. See tips from www.rabbit.org/rhdv to minimize the risk of spreading the virus on your clothing, shoes, and surfaces, using shoe covers and disinfecting with recommended products only in recommended concentrations. Effective disinfectants include: bleach (1:10 dilution), potassium peroxymonosulfate (Virkon), accelerated hydrogen peroxide (Prevail, Accel, and Peroxigard). Do not use these on or around your rabbits.
  • Keep mosquitoes and flies out of the home with window and door screens.
  • Keep dogs and other pets that go outdoors separate from your rabbits. Plan what to do if you have other pets that go outside, and consider flea control for them if you don't have it already. If your dog goes on hikes, be careful to wash paws with soapy water and not allow your pup to go into the same areas as your rabbit.
  • Do not feed greens that you have foraged (dandelions from the yard, for example). Look for commercial greens sources in areas that haven't had confirmed RHDV2 cases. Leafy greens that are grown in a greenhouse are probably safe. There is no way to truly "sterilize" leafy greens. It does make sense to rinse vegetables thoroughly to reduce general contaminants and dirt that could have virus sticking to them. Consider growing leafy greens in indoor hydroponic or aerogardens.
  • Feed hay that has been harvested at least 105 days prior. If you buy relatively fresh hay from a hay barn, find out where that hay was harvested and avoid hay from outbreak areas. Hay should be stored indoors only away from rodents or insects. You'll want to store it in cardboard boxes or other breathable container, or the hay could mold. Pre-packaged hay at least 3 months past harvest is likely safe.
  • Keep in mind that adherence to all the biosecurity measures above is no guarantee your rabbit will not be exposed to the virus. That is why most exotic veterinarians recommend vaccination.

If you see a deceased rabbit whose cause of death is unknown, do NOT touch the rabbit.
