Evaluating the need for standardised disease manifestation categories in patients infected with the tick-borne encephalitis virus: A Delphi panel.

Categorization systems for tick-borne encephalitis virus (TBEV) infection lack consistency in classifying disease severity. To evaluate the need for a standard, consensus-based categorisation system for TBEV infection across subtypes, we gathered an expert panel of clinicians and scientists with diverse expertise in TBEV infection. Consensus was sought using the Delphi technique, which consisted of 2 web-based survey questionnaires and a final, virtual, consensus-building exercise.

Clinical manifestations and outcomes of Tick-borne encephalitis: A systematic literature review.

Tick-borne encephalitis (TBE) is caused by a viral infection and can lead to acute and persistent damage to the central and peripheral nervous systems. Recently, the incidence of TBE in Europe has risen, and epidemiological patterns of disease have changed, emphasising the need for improved understanding of this vaccine-preventable disease. Although TBE is endemic in many countries, the disease spectrum of TBE is not well described.
