Tick-borne encephalitis (TBE)

Also called TBE

Tick-borne encephalitis (TBE) is a viral infection spread by the bite of an infected tick. It is found in forests and grassy areas in parts of central, eastern and northern Europe, including Romania, and Asia. Many people have no symptoms or a mild flu-like illness, but in some it causes inflammation of the brain (encephalitis) or its lining (meningitis).

What it is

There is no specific treatment; care in hospital supports the body while it recovers. Some people have lasting problems such as tiredness or memory difficulties.

A vaccine is available for people living in or travelling to risk areas. Covering skin, using insect repellent and checking for ticks after being outdoors help prevent it.

  • Flu-like symptoms, such as fever, tiredness and aches
  • A severe headache
  • A stiff neck
  • Confusion
  • Weakness or seizures

How it is usually diagnosed

  • Questions about tick bites and travel
  • Blood tests
  • Sometimes a lumbar puncture and brain scan

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:
