Milker nodes virus, also known as Milker's nodule virus or paravaccinia virus, is a DNA virus belonging to the Poxviridae family. It is primarily responsible for causing a localized skin infection in humans known as Milker's nodule.
The term "Milker nodes" refers to the small, raised lesions or nodules that form on the hands or fingers of individuals who come into contact with infected animals, particularly cows or sheep. These nodes typically appear red, blister-like, and can be painful.
The virus is primarily transmitted through direct contact with the infected animals or their secretions, such as milk, urine, or saliva. It can also be spread indirectly through contaminated objects or fomites. Individuals involved in livestock farming, veterinary work, or those in close proximity to animals are at higher risk of contracting this viral infection.
Symptoms of Milker nodes typically include the formation of painful nodules on the hands or fingers, which may later develop into vesicles or ulcers. There may also be associated symptoms like itching, tenderness, or swelling around the affected area. In some cases, there may be mild systemic symptoms like fever or fatigue.
While the infection is usually self-limiting and resolves within a few weeks without specific treatment, medical intervention may be required in some cases to alleviate symptoms or prevent complications. In rare instances, secondary bacterial infections or persistent nodules may occur, necessitating appropriate medical management.
Preventive measures primarily involve practicing good hand hygiene, wearing protective gloves while handling animals or animal products, and avoiding contact with infected animals or their secretions. Vaccination against related poxviruses used in veterinary settings may offer some degree of cross-protection against Milker nodes virus.
