Tick-Borne Encephalitis Now Likely in England
A new risk alert from a cross-government committee reveals that tick-borne encephalitis (TBE) is now probably present in England. The virus-carrying ticks have been found particularly around Norfolk, Suffolk, and the 123 area, but could be lurking elsewhere, as the tick species is widespread across the UK.
What is Tick-Borne Encephalitis?
TBE virus is common across Europe and spread by ticks. It can cause anything from no symptoms at all to mild flu-like illness. In severe cases, it can trigger meningitis or encephalitis, inflaming the brain and spinal cord.
Key symptoms include:
- High fever with headache
- Stiff neck
- Confusion or reduced consciousness
The virus’ rise in UK ticks has puzzled experts, but ongoing investigations suggest multiple factors are driving the increase.
Low Risk, But Stay Alert
The UK Health Security Agency (UKHSA) states the TBE risk to the public remains very low. However, they are stepping up hospital testing and surveillance, including monitoring people without symptoms in affected regions.
Ticks also carry Lyme disease, a bacterial infection treatable with antibiotics. UKHSA urges anyone spending time outdoors—especially in moorlands and woodlands—to check for ticks and remove them promptly and correctly.
Dr Meera Chand, Deputy Director at UKHSA: “Tick-borne encephalitis virus is very uncommon in the UK and the risk to the general population is very low. But ticks carry other infections including Lyme disease, so take steps to avoid bites and always check for ticks after outdoor activities.”
Know When to Get Help
If you’ve been bitten by a tick and feel unwell, speak to your GP immediately. Seek urgent medical help if you or someone else shows symptoms such as:
- Signs of meningitis: Severe headache, stiff neck, pain looking at bright lights
- Neurological symptoms: Seizures (if not epileptic), sudden confusion, weakness or paralysis, facial drooping, vision changes, or slurred speech
UKHSA continues to monitor ticks and other disease-carrying insects to protect public health from emerging threats.
