Lyme disease awareness after tick

Overview

Lyme disease is a bacterial infection you can get from the bite of an infected tick. Ticks are tiny bugs that live in woods, grassy areas, and parks. Not all ticks carry the bacteria that cause Lyme disease, but if a tick stays attached to your skin for a while (usually 24 hours or more) and is infected, you might get sick.

Lyme disease is not very common worldwide, but it happens more often in parts of Europe, North America, and Asia. In the UK, it is most common in grassy and wooded areas, especially in southern England and Scotland.

Anyone who spends time outdoors in tick habitats can get Lyme disease. People who hike, camp, garden, or have pets that bring ticks into the home are at higher risk. It can affect people of all ages, including children and older adults.

Symptoms

Common symptoms

• A red, circular rash that slowly expands over days – it may look like a bull's-eye target (but the rash can appear different on darker skin)
• Flu-like symptoms: fever, chills, headache, tiredness, muscle and joint aches
• Swollen lymph nodes

Symptoms in children

• Children may have the same rash and flu-like symptoms, but they might also complain of general discomfort or fatigue
• They may be irritable or have trouble sleeping
• Joint pain or swelling, especially in the knees, can occur

Symptoms in older adults

• Symptoms can be less obvious, such as vague joint pain or memory problems
• Older adults may have a higher risk of severe complications if not treated early
• Fatigue and general weakness are common

Causes

Main causes

• Being bitten by an infected tick that carries Borrelia bacteria
• The tick must usually be attached for at least 24 hours to transmit the infection

Risk factors

• Spending time in grassy, wooded, or heathland areas where ticks live
• Walking through long grass or undergrowth without protection
• Having pets that go outdoors and can bring ticks into your home
• Not checking your skin for ticks after being outdoors

When to see a doctor

See a doctor urgently if:

• If you develop a rash that looks like a bull's-eye or any expanding red rash after a tick bite
• If you have flu-like symptoms within a few weeks of a tick bite

Book a routine appointment if:

• If you find an attached tick and want advice on safe removal
• If you have mild joint pain or tiredness that does not improve

Diagnosis

Doctors diagnose Lyme disease based on your symptoms, a history of possible tick exposure, and sometimes blood tests. They will ask about outdoor activities and look for the typical rash.

Tests that may be done

• Blood tests that check for antibodies to the bacteria – these are more reliable a few weeks after infection
• Sometimes a test called ELISA (enzyme-linked immunosorbent assay), followed by a Western blot if the first test is positive

What to expect at your appointment

Your doctor will examine you, check your skin, and ask about your health. If Lyme disease is suspected early, they may start treatment even before blood test results come back. Blood tests may be repeated later to confirm the diagnosis.

Treatment

Lyme disease is treated with antibiotics. The earlier treatment starts, the better. Most people recover completely with a course of antibiotics taken by mouth. If the infection is more advanced or has affected the nervous system, antibiotics may be given by injection in a hospital.

Self-care at home

• Remove any attached tick as soon as possible using fine-tipped tweezers (grasp near the mouthparts and pull steadily upward)
• Clean the bite area with soap and water or antiseptic
• Rest and drink plenty of fluids if you have flu-like symptoms
• Take over-the-counter pain relief such as paracetamol or ibuprofen for aches and fever (always follow the label or ask your pharmacist)

Medical treatments

Doctors prescribe a course of oral antibiotics that typically lasts 10 to 21 days. For more severe cases, intravenous (IV) antibiotics may be given in hospital for up to 28 days. It is important to finish the entire course even if you start feeling better.

When is surgery considered?

Surgery is not used to treat Lyme disease. In rare cases where joint damage occurs, joint surgery might be considered for long-term complications, but this is not common.

Living with this condition

Most people with Lyme disease recover fully after treatment. However, some may experience persistent symptoms like fatigue, muscle pain, or memory problems for weeks or months. This is called post-treatment Lyme disease syndrome. Rest, pacing activities, and gentle exercise can help manage these symptoms.

Lifestyle tips

• Get enough sleep and rest when tired
• Return to normal activities gradually
• Use relaxation techniques like deep breathing if you feel anxious about your health

Diet and exercise

A balanced diet with plenty of fruits, vegetables, and protein supports recovery. Gentle exercise such as walking, stretching, or swimming can help maintain strength and energy levels. Avoid overexertion.

Mental health and emotional wellbeing

Living with Lyme disease can be frustrating, especially if symptoms last longer than expected. Some people feel anxious or depressed. It is important to talk to your doctor if you are struggling emotionally. Talking therapies and support groups can help.

Prevention

Yes, you can reduce your risk of Lyme disease by avoiding tick bites and removing ticks quickly. Wear long sleeves and trousers in tick areas, tuck trousers into socks, use insect repellent containing DEET on exposed skin, and stick to paths when walking. Check your skin, hair, and clothing for ticks after being outdoors. Also check your pets and children. If you find a tick, remove it correctly and monitor the area.

Vaccines

There is currently no vaccine available for Lyme disease in the UK or most countries. Research is ongoing.

Screening programmes

Routine screening for Lyme disease is not recommended for the general public. Testing is done only if you have symptoms and a possible tick exposure.

Complications

If left untreated

• Chronic joint inflammation (Lyme arthritis), especially in the knees
• Nervous system problems such as meningitis (inflammation of the brain and spinal cord lining), facial palsy, or nerve pain
• Heart problems like inflammation of the heart muscle or irregular heartbeat
• Long-term fatigue, memory problems, and difficulty concentrating (post-treatment Lyme disease syndrome)

Long-term outlook

With early diagnosis and proper treatment, almost everyone with Lyme disease gets better completely. Even if complications develop, most people respond well to treatment. The outlook is very good, especially when you see a doctor as soon as symptoms appear.
