Rare tick-borne infections diagnosed in England
PHE is calling for people to be tick aware after the first case of a babesiosis was diagnosed in England.
Public Health England (PHE) has confirmed the diagnosis of a case of babesiosis and a probable case of tick-borne encephalitis (TBE) in England. This is the first record of a UK-acquired case of babesiosis and the second case of TBE being acquired in the UK.
Babesiosis is caused by a parasite which infects red blood cells whilst TBE is a viral infection that affects the central nervous system. Both are rare infections spread by the bite from an infected tick.
A spokesman for PHE said both patients have been transferred to hospital, where they are receiving appropriate treatment and supportive care.
The spokesman said the risk of babesiosis or TBE for the general public is very low. However, a number of infections can develop following a tick bite, including Lyme disease, and there are things we can all do to reduce our risk of being bitten by ticks while enjoying the outdoors this summer.
PHE says it is important to ‘be tick aware’ and take precautions to reduce your risk of being bitten by ticks when enjoying green spaces this summer including, keeping to footpaths and avoiding long grass when out walking. Wearing appropriate clothing such as a long-sleeved shirt, and trousers tucked into your socks makes it less likely that a tick will bite and attach. Considering the use of repellents containing DEET and making it a habit to carry out a tick check regularly when you’re outdoors and when you get home
If you have been bitten by a tick, it should be removed as soon as possible using fine-tipped tweezers or a tick removal tool which is sold by many outdoor stores, vets and pharmacies. Grasp the tick as close to the skin as possible and pull upwards slowly and firmly. Once removed, wash your skin with water and soap, and apply an antiseptic cream to the skin around the bite Contact your GP promptly if you begin to feel unwell, remembering to tell them you were bitten by a tick or recently spent time outdoors.
Dr Katherine Russell, consultant in the Emerging Infections and Zoonoses team at PHE, said: ‘It is important to emphasise that cases of babesiosis and TBE in England are rare and the risk of being infected remains very low. Lyme disease remains the most common tick-borne infection in England.
‘Ticks are most active between spring and autumn, so it is sensible to take some precautions to avoid being bitten when enjoying the outdoors. Seek medical advice if you start to feel unwell after a tick bite.’
A spokesman for PHE said it regularly undertakes work to understand the potential risks of tick-borne infections in England. This year, PHE has surveyed sites in Devon close to where the person with babesiosis lives, collecting and testing hundreds of ticks – all tested negative for the parasite which causes babesiosis.
PHE tested deer blood samples from Hampshire in areas near to where the person with probable TBE lives and they have shown evidence of likely TBE virus infection, which matches similar results found in 2019.
