<unk>  is caused by a virus transmitted through the bite of an infected<unk> . Three types of the virus exist, including the Far East, European, and Siberian subtypes. The Ixodidae family of<unk> s is the primary vector associated with transmission, with other modes of transmission including the consumption of unpasteurized, raw milk. Pathogenesis occurs as the virus binds to a host cell receptor. Through a series of reactions, the virus enters the cell, is translated, and hi-jacks the host cell's replication machinery. After which immature virions are released within the cell, to ultimately spread infection. Viral replication will often occur within subcutaneous tissue. Replication also occurs within the lymph nodes, causing immense damage to the immune system. A later phase of the virus results in an infection of the CNS as the immune response increases the  permeability of the blood-brain barrier.
