Tick-Borne Encephalitis Virus Hits England – But Risk Remains Low
A new government-backed risk assessment warns that tick-borne encephalitis virus (TBEV) is now likely present in England. This comes after confirmed cases and virus detections in ticks across several counties.
Confirmed Cases and Virus Hotspots
- Since 2019, three probable or confirmed TBE cases have been recorded in England.
- The first-ever confirmed case in England was linked to Yorkshire in 2022.
- The virus has also been found in ticks in Hampshire, Dorset, and at the Norfolk-Suffolk border.
- The tick species that carry TBEV are widespread across the UK, suggesting the virus may be more widespread than currently known.
What is Tick-Borne Encephalitis?
TBEV is a virus carried by ticks, common throughout Europe and beyond. It can cause anything from no symptoms to severe brain infections like meningitis or encephalitis.
Symptoms mimic meningitis and include high fever, headache, stiff neck, confusion, or loss of consciousness.
Experts Urge Vigilance Despite Low Risk
The UK Health Security Agency (UKHSA) says the public risk remains very low but is stepping up hospital testing and surveillance to catch new cases early. They’ll also monitor asymptomatic people in affected areas.
Dr Meera Chand, UKHSA Deputy Director, said: “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 too, including Lyme disease. Take precautions when outdoors in tick-prone spots like moorlands and woodlands, and check yourself for ticks.”
How to Stay Safe
- Check yourself thoroughly for ticks after being outdoors.
- Remove any ticks promptly and correctly to reduce infection risk.
- Seek GP advice if unwell after a tick bite.
- Get urgent medical help if experiencing meningitis symptoms:
- Severe headache
- Stiff neck
- Pain when looking at bright lights
- Watch for neurological signs, including:
- Seizures (if you’re not epileptic)
- Sudden confusion or behaviour changes
- Weakness or loss of movement in limbs
- Facial drooping, vision changes, or slurred speech
UKHSA continues to monitor ticks, mosquitoes, and the diseases they carry to track emerging health threats in the UK.
