Tick-borne viral encephalitis
ICD-10 A83 is a billable code used to indicate a diagnosis of tick-borne viral encephalitis.
Tick-borne viral encephalitis (TBE) is a viral infection that affects the central nervous system, primarily transmitted through the bite of infected ticks. The disease is caused by the tick-borne encephalitis virus (TBEV), which is prevalent in certain regions of Europe and Asia. Clinically, TBE can present in three phases: an initial phase characterized by flu-like symptoms such as fever, headache, and fatigue; a second phase where neurological symptoms emerge, including meningitis, encephalitis, or meningoencephalitis; and a potential third phase that may involve severe neurological complications such as paralysis or cognitive impairment. The severity of the disease can vary significantly, with some patients recovering completely while others may experience long-term neurological deficits. Vaccination is available and recommended for individuals at high risk, such as those living in endemic areas or engaging in outdoor activities in these regions. Early diagnosis and supportive care are crucial for improving outcomes in affected patients.
