Lyme Disease Prevention: A UK Guide to Ticks and Travel Safety

Lyme disease is a bacterial infection that can be spread to humans by infected ticks. In the United Kingdom, these are usually sheep ticks or wood ticks found in woodland, heathland, and tall grass. While not every tick carries the Borrelia burgdorferi bacteria, the number of cases in the UK has been steadily rising, making awareness essential for anyone enjoying the outdoors.

According to NHS guidance, the infection is most commonly contracted between early spring and autumn when ticks are most active. Ticks do not fly or jump; instead, they wait on vegetation and cling to passing humans or animals in a process known as 'questing'. Once on the skin, they seek a warm, moist area to attach and begin a blood meal.

The most distinctive symptom of Lyme disease is a characteristic skin rash called erythema migrans. This rash typically appears 3 to 30 days after a tick bite. It often looks like a bullseye on a target, with a central red spot surrounded by a clear area and then a further red ring. However, it is important to note that the rash can be solid red or faint, especially on darker skin tones where it may look like a bruise.

• Flu-like symptoms: Many patients experience high temperature, chills, headaches, and muscle or joint pain.
• Fatigue: A profound sense of tiredness is common in the early stages.
• Neurological issues: If left untreated, the bacteria can affect the nervous system, leading to facial drooping or nerve pain.

NICE (National Institute for Health and Care Excellence) guidelines suggest that if the bullseye rash is present, a clinical diagnosis of Lyme disease can be made even without a blood test, and treatment should begin immediately.

If you find a tick attached to your skin, the goal is to remove it as quickly as possible without squeezing the body. Squeezing can cause the tick to regurgitate bacteria into your bloodstream. The UK Health Security Agency recommends the following steps:

1. Use fine-tipped tweezers or a specialized tick-removal tool (available from most UK pharmacies).
2. Grasp the tick as close to the skin as possible (by its mouthparts).
3. Pull upwards firmly and steadily. Do not jerk or twist, as this can break off the mouthparts in the skin.
4. Once removed, clean the bite area with antiseptic or soap and water.
5. Dispose of the tick by flushing it down the toilet or placing it in a sealed bag in the bin.

What NOT to do

Avoid traditional 'remedies' such as burning the tick with a match, covering it in petroleum jelly, or using nail varnish. these methods increase the risk of infection by stressing the tick.

Prevention is the most effective way to avoid Lyme disease whether you are hiking in the Scottish Highlands or trekking through European forests. Implementing these habits can significantly lower your risk:

• Cover up: Wear long-sleeved shirts and tuck your trousers into your socks to prevent ticks from reaching your skin.
• Light colours: Light-coloured clothing makes it easier to spot dark ticks before they attach.
• Use repellent: Apply insect repellent containing DEET, Icaridin, or Citriodiol to exposed skin and clothing.
• Stay on paths: Avoid walking through long grass or dense brush where ticks are most concentrated.
• Tick checks: After being outdoors, perform a thorough check of your entire body, paying close attention to the backs of knees, groin, armpits, and hairline.

If you have been bitten by a tick or have spent time in a high-risk area, you should monitor your health closely for several weeks. You should book a consultation to speak to a GP online in the UK if:

• You develop a circular red rash that is expanding.
• You experience a high temperature, shivering, or persistent headaches following an outdoor trip.
• You are concerned that you did not remove the tick correctly and part of it remains in the skin.
• You are travelling and need advice on whether your symptoms require immediate antibiotic intervention.

An online GP can assess your symptoms, view photos of a suspected rash, and provide a private prescription for the appropriate course of antibiotics (usually doxycycline) if Lyme disease is suspected. Early treatment is highly effective and usually leads to a full recovery.

The standard treatment for early-stage Lyme disease in the UK involves a two-to-three-week course of antibiotics. It is vital to complete the full course even if you feel better after a few days. For most people, this clears the infection entirely.

A small number of patients may experience 'Post-treatment Lyme Disease Syndrome' (PTLDS), which involves lingering symptoms like fatigue and muscle aches. While the exact cause is debated, current NICE guidelines focus on managing these symptoms and providing supportive care rather than prolonged antibiotic use, which has not been proven effective for long-term recovery.
