TBE (Tick Borne Encephalitis) or tick-borne brain inflammation (encephalitis) is caused by a so-called flavivirus. It can manifest as encephalitis and meningitis with high fever, severe headache, neck stiffness and paralysis symptoms. Deaths are very rare.
The first signs of illness are noticed 1–2 weeks after being infected. The disease begins with fever.
There is no known cure.
In Sweden, TBE is most common near the Baltic Sea, and in areas around Lake Vättern and Vänern. But the disease has spread to the west coast, and occurs in large parts of southern and central Sweden.
