Tick-Borne Encephalitis Found In UK

A disease that can harm the brain, and which is spread to humans through tick bites, has been identified in the UK for the first time. Public Health England (PHE) confirmed the presence of the tick-borne encephalitis virus in Thetford Forest, Norfolk, and on the Hampshire-Dorset border. PHE said it believed a “handful” of infected ticks had been found in both locations, with only one highly probable case of tick-borne encephalitis so far. The health body said the risk was very low but it was investigating how common ticks with the virus might be.

The small parasitic arachnids are becoming more common in parts of the UK, mainly due to increasing deer numbers. As well as living on deer, ticks can be found on cats, dogs and urban foxes. Ticks can also live in the undergrowth and latch on to humans when they walk through long grass. In addition to the encephalitis virus, the parasites can carry other diseases, including the more common Lyme disease.

Dr Nick Phin, of PHE, said, “These are early research findings and indicate the need for further work. However, the risk to the general public is currently assessed to be very low.” Most people who catch the encephalitis virus will have no or only mild flu-like symptoms, but it can affect the brain and central nervous system and can sometimes be fatal. A vaccine is available privately for tick-borne encephalitis, which is already present in mainland Europe and parts of Asia. It is thought infected ticks may have arrived in the UK via migratory birds. “We are reminding people to be ‘tick aware’ and take tick precautions, particularly when visiting or working in areas with long grass such as woodlands, moorlands and parks,” Dr Phin said.

The NHS says tick bites can be prevented by covering skin while walking outdoors, using existing paths and nature trails, applying insect repellent and checking your clothes and hair after going for a walk. According to the Encephalitis Society, a charity that supports people affected by all types of encephalitis, less than 2% of people die from the viral infection. The illness begins with flu-like symptoms before progressing to a more serious second phase with meningitis and swelling of the brain in a quarter of cases.

How to remove a tick

  1. Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
  2. Pull upward with steady, even pressure. Don’t twist or jerk the tick; this can cause the mouth-parts to break off and remain in the skin. If this happens, remove the mouth-parts with tweezers. If you are unable to remove the mouth easily with clean tweezers, leave it alone and let the skin heal.
  3. After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol or soap and water.
  4. Never crush a tick with your fingers. Dispose of a live tick by putting it in alcohol, placing it in a sealed bag/container, wrapping it tightly in tape, or flushing it down the toilet.


If you develop a rash or fever within several weeks of removing a tick, see your doctor. Be sure to tell the doctor about your recent tick bite, when the bite occurred, and where you most likely acquired the tick. Avoid folklore remedies such as “painting” the tick with nail polish or petroleum jelly, or using heat to make the tick detach from the skin. Your goal is to remove the tick as quickly as possible–not waiting for it to detach.
