Abstract
Rabbit haemorrhagic disease (RHD) is a highly fatal, contagious disease of domestic and wild adult rabbits. RHD was first reported in china in 1984 (Liu et al. 1984), subsequently, RHD has been reported through Asian countries, then spread in European and American countries. In Egypt, RHDV has been diagnosed for the first time by (Salem and El-Ballal, 1992).The etiological agent of RHD is a member of Caliciviridae, is a single stranded RNA, non enveloped, replicates in the cytoplasm. RHDV is environmentally stable, highly infectious, and transmissible by close contact or by contact with fomites such as contaminated fur, clothing, or cages. In direct arthropod vectors, including blow flies or flesh flies have been implicated in the spread of RHDV.
