The urgency of the problem of viral tick-borne encephalitis in Primorsky Krai is due to both the breadth of its spread and the wide variety of clinical variants. Over the past 5 years (2019–2023), febrile form prevailed (55.1%), focal (25.9%), meningeal (6.9%), and infrequent (12.1%) forms. The mortality rate for the same period was 10.3%. In 2023, the mortality rate was 23.1%, the mortality rate was 0.17% per 100,000 population. The purpose of the publication is to draw the attention of doctors to a known disease, to recall the clinic of the focal form that arose as a result of ignoring vaccination. The article provides a clinical example of a patient with chronic tick-borne viral encephalitis, an initial progressive continuously progressive variant, encephalopolyomyelitis with the development of flaccid, mainly upper, deep tetraparesis, left-sided peripheral prosoparesis, bulbar, pseudobulbar syndromes, pelvic organ dysfunction.
