Down the Rabbit Hole: Domestic Rabbit Owners' Perceptions of Rabbit Hemorrhagic Disease Virus 2

Rabbit hemorrhagic disease virus 2 (RHDV2) is a highly contagious pathogen that infects wild and domestic rabbits and hares (lagomorphs). Globally, RHDV2 has resulted in substantial economic losses for commercial rabbit trade and caused wild lagomorph population declines. Previous research on RHDV2 suggests that human-mediated movement of rabbits may contribute to the spread of RHDV2. We conducted the first survey of individuals who own or interact with domestic rabbits to identify their rabbit husbandry behaviors and knowledge of, and concerns about, RHDV2. In 2021, we surveyed 1807 rabbit owners, breeders, and rescue staff in the USA. Respondents had a high level of knowledge about RHDV2. Respondents believed RHDV2 posed a high risk to rabbit-related activities and were concerned about its economic and ecological impacts. Nearly half of respondents always kept their rabbits indoors, but 10.7% of respondents allowed their rabbits outside frequently on properties used by wild lagomorphs. Respondents with five rabbits or less were generally willing to vaccinate their rabbits, but respondents with larger herds argued that vaccines were cost prohibitive. Given respondents' concerns about RHDV2, communication about disease prevention should highlight the adverse ecological and economic consequences of RHDV2.
