<unk> -borne diseases are most often transmitted during a blood meal, either by a nymph of adult<unk> . Blood meals will occur with a higher rate of incidence from the late spring into the early fall, with the highest rate of<unk>  viral <unk> V) infections during the early and late summer. The primary disease vector for<unk> V is the Ixodidae<unk>  family, found throughout most of Eurasia. The virus itself is a member of the flavivirus genus, with three distinct subtypes. The virus is a (+) ssRNA genome enclosed in a capsid protein. It begins by locating a host cell receptor. The virus is internalized through the process of endocytosis. During this time the virus hi-jacks the host cells replication machinery, in order to replicate many times within the host cell. Upon completion the cell releases many immature virions for further progression of the disease. Progression of the disease results in an infection of the central nervous system, with clinical manifestation such as meningitis and encephalitis.
