Äläinmallirokkoja

Äläinmallirokkoja, also known as rodent pox or poxviruses of rodents, refers to a group of orthopoxviruses that infect various rodent species. These viruses are closely related to other well-known orthopoxviruses such as variola virus (smallpox) and vaccinia virus. Infection typically results in a dermatological condition characterized by skin lesions.

The clinical presentation in rodents can vary depending on the specific virus strain and the host species. Common symptoms include papules, vesicles, pustules, and scabs, often appearing on the skin of the face, ears, limbs, or tail. In some cases, systemic illness may occur, with symptoms like lethargy, decreased appetite, and respiratory distress. Transmission is usually through direct contact with infected animals or their contaminated environments, and possibly through aerosolized particles.

Several rodent species are known to be susceptible, including mice, rats, gerbils, and guinea pigs. These viruses are of zoonotic concern, meaning they can potentially be transmitted to humans. While human infections are rare, they can occur through close contact with infected rodents or their excretions. Symptoms in humans are usually mild, resembling a localized rash or a mild systemic illness, but immunocompromised individuals may be at higher risk of more severe disease. Diagnosis is typically made through laboratory methods, including PCR and serological tests. Prevention strategies focus on rodent control and avoiding direct contact with potentially infected animals.
