Rabbitpox is a disease of rabbits caused by a virus of the genus Orthopoxvirus and the family Poxviridae. Rabbitpox was first isolated at the Rockefeller Institute in New York in 1933, following a series of epidemics in the laboratory rabbits. It is an acute disease only known to infect laboratory rabbits as no cases have been reported in wild rabbits; it also cannot infect humans.

History
Rabbitpox has not been recognised in wild rabbits, however a few outbreaks have been reported in the USA since 1930.
Symptoms
Infection
Rabbitpox virus is a highly infectious airborne agent, which spreads very rapidly through laboratories which contain rabbits causing a high rate of mortality. Because of the edematous condition, “poxless” rabbitpox may be confused with myxomatosis. The virus may be isolated or the infection diagnosed serologically by methods appropriate to vaccinia. Spread through a rabbitry is rapid, but rabbits inoculated with smallpox vaccine are immune.
Rabbitpox virus is closely related immunologically to vaccinia virus, consequently rabbits that have been inoculated with the smallpox (vaccinia virus) vaccine have immunity against rabbitpox.
Danger to humans
Rabbitpox virus does not infect humans.
