Transmission and clinical syndromes
Eyach virus is acquired by tick bite. The tick gets infected after a blood meal from a vertebrate host, which is suspected to be the European rabbit O. cunniculus.[2] Eyach virus has been linked to tick-borne encephalitis, as well as polyradiculoneuritis and meningopolyneuritis, based on serological samples of patients with these neurological disorders.
