Lyme Disease and Tick Safety: A UK Guide to Prevention and Removal

Lyme disease, or Lyme borreliosis, is a bacterial infection that can be spread to humans by infected ticks. In the UK, ticks are most commonly found in grassy and wooded areas, including popular hiking spots like the Scottish Highlands, the Lake District, and the South Downs. According to NHS guidance, while not every tick carries the bacteria that causes Lyme disease, it is essential to be aware of the risks and symptoms if you spend time outdoors.

The infection is caused by the bacterium Borrelia burgdorferi. In the UK, cases are increasing, partly due to changing climate patterns and increased public awareness. Most people who are treated with a full course of antibiotics in the early stages make a complete recovery. However, if left untreated, the infection can spread to the nervous system, joints, and heart, leading to more chronic health issues.

One of the most distinctive symptoms of Lyme disease is a characteristic skin rash known as erythema migrans. This rash typically appears within 3 to 30 days after being bitten by an infected tick. It often looks like a bullseye on a target, with a central red spot surrounded by a clear area and then an outer red ring.

• The rash is usually not itchy or painful.
• It can expand slowly over several days or weeks, reaching up to 30cm across.
• It may appear faint on darker skin tones, appearing more like a bruise or a dusky patch.

It is important to note that approximately 1 in 3 people infected with Lyme disease do not develop a rash at all. In these cases, the infection may present as 'flu-like' symptoms, including high temperature, headache, muscle and joint pain, and fatigue.

If you find a tick attached to your skin, you should remove it as soon as possible. The risk of getting Lyme disease is very low if the tick is removed within the first 24 hours. However, you must remove it correctly to avoid squeezing the tick's body, which can increase the risk of infection.

The Correct Technique:

• Use fine-tipped tweezers or a specialized tick-removal tool (available from most UK pharmacies).
• Grasp the tick as close to the skin as possible.
• Pull upwards slowly and firmly without twisting or jerking, as this can cause the mouthparts to break off and remain in the skin.
• Clean the bite area with antiseptic or soap and water.

Do not use lit cigarettes, alcohol, or nail varnish to try and 'suffocate' the tick, as these methods are ineffective and may cause the tick to regurgitate bacteria into your bloodstream.

Prevention is the best defence against tick-borne illnesses. When walking in areas with long grass or heavy woodland, follow these NICE-aligned prevention tips:

• Cover up: Wear long-sleeved shirts and tuck your trousers into your socks to prevent ticks from reaching your skin.
• Use repellent: Apply insect repellent containing DEET to your skin and clothing.
• Stick to paths: Avoid walking through deep leaf litter or tall grass where ticks are most active.
• Check yourself: Perform a 'tick check' on yourself, your children, and your pets after being outdoors. Pay close attention to warm, hidden areas like the armpits, groin, behind the knees, and the hairline.
• Light clothing: Wear light-coloured fabrics so that ticks are easier to spot and brush off before they attach.

If you have been bitten by a tick or have recently spent time in a high-risk area and notice any symptoms, you should seek medical advice. You can speak to a GP online to discuss your concerns and show them any rashes via a video consultation.

A GP will typically diagnose Lyme disease based on your symptoms and a history of a tick bite. NICE guidelines state that if the characteristic bullseye rash is present, a doctor should start antibiotic treatment immediately without waiting for blood test results. If you do not have a rash but have other symptoms, the GP may arrange a blood test. It is worth noting that blood tests taken too early (within the first few weeks) can sometimes return a false negative, as it takes time for the body to develop antibodies.

An online GP service is a convenient way to get a professional assessment, especially if you are travelling within the UK or cannot easily access your local surgery. If necessary, they can provide a prescription for the appropriate antibiotics, usually doxycycline or amoxicillin.

The standard treatment for early-stage Lyme disease is a two-to-three-week course of oral antibiotics. It is vital to finish the entire course, even if you start to feel better before the end. Most people find that their symptoms begin to clear up within a few days of starting treatment.

Some individuals may experience lingering symptoms such as tiredness or muscle pain after the infection has been treated. This is sometimes referred to as 'Post-treatment Lyme Disease Syndrome'. While the cause is not fully understood, it is not thought to be a persistent infection, and further antibiotics are usually not recommended. If you experience persistent symptoms, your GP can help you manage them with a tailored recovery plan.
