RHDV-2 DETAILS
Rabbit Hemorrhagic Disease Virus (RHDV2)

Prior to 2020, RHDV outbreaks were rare and contained.

In 2020, a major outbreak began in the Southwest U.S. and rapidly spread.

The disease is now endemic in Colorado.
Vaccination Is Critical
We strongly recommend vaccinating your pet rabbits against RHDV2.
-
The vaccine requires an initial two-dose series, followed by
annual boosters. -
Talk to your rabbit-savvy vet to schedule vaccinations.
Practice Good Biosecurity
Even if your rabbit is vaccinated, biosecurity helps reduce risk:
-
Keep rabbits indoors (recommended for many reasons).
-
No outdoor playtime or foraging.
-
Remove shoes before entering your home.
-
Wash hands before and after handling your rabbits.
-
Quarantine any new rabbits before introducing them to others.

Seizures
