Lyme Disease and Travel: UK Prevention, Symptoms, and Treatment

Lyme disease, or Lyme borreliosis, is a bacterial infection transmitted through the bite of an infected tick. In the United Kingdom, the primary culprit is the Ixodes ricinus tick, commonly known as the sheep tick or wood tick. These tiny arachnids are typically found in tall grasses, woodland, and moorland areas where they wait to latch onto passing animals or humans.

While the risk of contracting Lyme disease in the UK is relatively low, cases have been rising as more people engage in outdoor travel and domestic staycations in rural hotspots like the Scottish Highlands, the Lake District, and the New Forest. According to NHS guidance, there are approximately 3,000 to 4,000 laboratory-confirmed cases in England and Wales each year, though the actual number may be higher due to under-reporting.

The most distinctive symptom of Lyme disease is a skin rash called erythema migrans. This rash often looks like a bullseye on a target, with a central red spot surrounded by a clear area and then an outer red ring. However, it is important to note that about 1 in 3 people infected with Lyme disease do not develop this rash.

Early stage symptoms (1 to 4 weeks):

• A circular or oval rash that expands over several days.
• Flu-like symptoms, including a high temperature, chills, and muscle aches.
• Headaches and stiff neck.
• Persistent fatigue or a general feeling of being unwell.

The rash is usually not itchy or painful, but it can feel warm to the touch. If left untreated, the infection can spread through the bloodstream, leading to more severe complications in the joints, heart, and nervous system.

When travelling to rural areas in the UK or abroad, prevention is the best line of defence. Ticks do not fly or jump; they 'quest' by clinging to vegetation. To reduce your risk, you should:

• Wear long-sleeved shirts and tuck your trousers into your socks.
• Stick to clearly defined paths rather than walking through tall grass.
• Use an insect repellent containing DEET on your skin and clothes.
• Perform a 'tick check' on yourself, your children, and your pets after being outdoors.

How to remove a tick safely:

If you find a tick attached to your skin, do not panic. Use fine-tipped tweezers or a specific tick-removal tool (available at many UK pharmacies). Grasp the tick as close to the skin as possible and pull upwards with a steady, even pressure. Avoid twisting or squeezing the tick, as this can cause it to regurgitate bacteria into your bloodstream. After removal, clean the area with antiseptic or soap and water.

Many patients feel anxious after discovering a tick bite. While not every bite requires immediate medical intervention, you should speak to a GP online if you develop any symptoms within a month of a bite, or if you notice the characteristic bullseye rash. A GP can provide an assessment based on your history of exposure and visual symptoms.

In the UK, NICE (National Institute for Health and Care Excellence) guidelines suggest that if an erythema migrans rash is present, treatment with antibiotics should be started immediately without waiting for a blood test. If a rash is not present but symptoms suggest Lyme disease, your doctor may arrange a blood test to look for antibodies. When you consult an online GP, you can upload clear photographs of your rash, which helps significantly with a quick diagnosis and the issuance of a private prescription if required.

If Lyme disease is suspected or confirmed, the standard treatment is a course of antibiotics, usually doxycycline or amoxicillin. The duration of the course typically lasts between 14 to 21 days, depending on the severity of the symptoms. It is vital to finish the entire course, even if you begin to feel better after a few days.

Most people who are treated early with the correct antibiotics make a full and rapid recovery. However, some individuals may experience persistent symptoms such as fatigue or muscle pain even after treatment. This is sometimes referred to as 'Post-treatment Lyme Disease Syndrome'. Ongoing support from your GP or a specialist may be necessary if symptoms do not resolve.
