Myxomatosis in RabbitsMyxomatosis is a viral disease in pet and wild rabbits. In the US, this contagious disease is mainly located on the West Coast. Cottontail rabbits are the normal host of the virus and it rarely causes disease in them. This Myxoma virus, a type of pox virus, was intentionally introduced to wild rabbits in Europe and Australia to help reduce rabbit populations, and, sadly, the virus has continued to spread to the pet rabbits also. The myxoma virus has many strains. The US West Coast strain is the most deadly, killing 99% of infected rabbits.Are you concerned about your pet?Book a video consultation with an experienced veterinarian within minutes.
