【How do rabbits with RHD die? 】

Rabbits that are infected with RHDV first develop symptoms anywhere from 24-72 hours after infection and usually succumb within 6-36 hours after the first symptoms appear.

Many infected animals show no signs of disease and die suddenly. Some animals may exhibit lethargy or excitement before death. Animals die from the rapid onset of multiple organ failure.

Given the short disease time and the sudden death from rapid organ failure, RHDV continues to be one of the most humane control methods for rabbits

If it takes 48 hours to kill the rabbit, doesn’t the rabbit suffer during this time?

RHDV is one of the more humane methods of controlling wild rabbits. Basically the rabbits end up with ‘cold-like’ symptoms, become lethargic and then die quickly.
Post-infection, there is a rise in body temperature lasting up to 24 hours, followed, in 70–90% of cases, by death up to 48 hours after the onset of a fever (see Humaneness assessment: bait delivery of RHDV).

【How does RHDV spread naturally? 】

RHDV is spread by insect vectors, such as bushflies and blowflies. Direct contact between a rabbit and a rabbit carcass with RHDV is also an avenue of spread.
Animals that predate on rabbit carcasses such as foxes, dogs and cats may also excrete the virus in their faeces.

Does it affect people or other animals (pet, native wildlife and livestock)? 
In Australia, no variant of RHDV1 has ever been found to cause infection in any other animal except the European rabbit (Oryctolagus cuniculus).
Even predatory animals that eat rabbits that have died from RHDV1 do not develop an infection.
