Sheep Contagious Pustular Dermatitis Virus, also known as sheep orf virus, is a highly contagious viral infection that affects sheep and goats. It belongs to the family Poxviridae and is a member of the genus Parapoxvirus.
The disease caused by this virus is called contagious pustular dermatitis, or orf. It is characterized by the formation of pustules or blisters on the skin, particularly around the mouth, lips, nose, and feet of infected animals. These pustules are often painful and can cause discomfort, leading to reduced feed intake and weight loss.
Sheep Contagious Pustular Dermatitis Virus is primarily transmitted through direct contact with infected animals or through indirect contact with contaminated materials, such as bedding or feed. It can also spread through skin abrasions and insect bites. Once an animal is infected, the virus replicates in the skin cells, causing the formation of pustules. The virus can remain viable in the environment for several months, making it a persistent threat to susceptible animals.
Sheep Contagious Pustular Dermatitis Virus is not considered a significant risk to human health, but it can occasionally cause mild dermatitis in individuals who come into direct contact with infected animals or their secretions.
Management and prevention of the disease include strict biosecurity measures, such as isolation and quarantine of affected animals, proper disinfection of housing areas, and vaccination. Treatment of infected animals typically involves supportive care, including pain relief and wound management.
In summary, Sheep Contagious Pustular Dermatitis Virus is a highly contagious viral infection that causes contagious pustular dermatitis in sheep and goats, resulting in the formation of painful pustules or blisters on the skin.
