Brief overview of Rabbit Hemorrhagic Disease
Rabbit Hemorrhagic Disease, also known as RHD, is a viral disease that primarily affects rabbits. It is caused by the Rabbit Hemorrhagic Disease Virus (RHDV), which is a highly contagious and often fatal virus. The disease is characterized by internal bleeding, liver damage, and high mortality rates among infected rabbits. RHD can spread rapidly through direct contact with infected rabbits or their bodily fluids, as well as indirect contact through contaminated objects or surfaces.
Historical context of the disease
The first cases of Rabbit Hemorrhagic Disease were reported in China in 1984, where it caused significant losses in domestic rabbit populations. The disease later spread to Europe, where it had devastating effects on both wild and domestic rabbit populations. In recent years, RHD has been detected in various other parts of the world, including North America. The global spread of the disease has raised concerns among wildlife and agriculture officials, as it poses a threat to both domestic and wild rabbit populations.
Current knowledge about the disease
Rabbit Hemorrhagic Disease is caused by the Rabbit Hemorrhagic Disease Virus (RHDV), which belongs to the Caliciviridae family. The virus is highly contagious and can survive in the environment for extended periods, allowing it to infect new hosts even after the initial outbreak. There are several known strains of RHDV, with varying levels of virulence. The disease primarily affects rabbits, both domestic and wild, although other lagomorphs such as hares may also be susceptible to infection.
