October 2023 Update

In October, we received submissions from NSW, VIC, WA, QLD, SA and ACT. This month, our submissions more than doubled compared to the last two months, which correlates with increased insect activity in hotter weather. RHDV2 remains the dominant circulating strain in positive cases and seems to be active in NSW, VIC, WA, SA and ACT. No positive cases were detected in QLD during October

Calicivirus was not detected in 37.5% of our samples. However, as calicivirus was detected in other rabbits located in the same states as those who tested negative, we would still urge rabbit owners to continue to be cautious:

• Decontaminate hands, shoes and clothing before handling rabbits
• Keep your pet rabbit indoors
• Regularly decontaminate equipment and materials including cages, hutches, bowls etc, with either 10% bleach, 10% sodium hydroxide, or a parvocidal disinfectant such as F10SC or Virkon
• Control insects (especially flies) as much as possible both indoors and outdoors
• Rabbit-proof your backyard to prevent access by wild rabbits
• Limit contact between and handling of unfamiliar pet rabbits

Additionally, pet rabbits should be vaccinated with Cylap® or Filavac® (AVA). Please note that it will take a few weeks for rabbits to build up their immunity following vaccination.

If you suspect a rabbit may have died of calicivirus, you can request a free test kit by sending an email to rabbitcalicivirus@csiro.au with your postal address.
