Lyme disease is a bacterial infection spread to humans through the bites of infected black-legged ticks (also known as deer ticks). It is most common in grassy or wooded areas and is typically easier to treat when diagnosed early.
Symptoms and Stages
Symptoms usually appear in stages, though they can overlap.
#Early Localised (3–30 days): The most distinct sign is a circular “bullseye” rash (erythema migrans) at the bite site. Other symptoms include fever, chills, headache, fatigue, and muscle or joint aches.
#Early Disseminated (Weeks to months): If untreated, the infection spreads, potentially causing facial palsy (drooping), multiple rashes, heart palpitations, or severe nerve pain and numbness.
#Late Disseminated (Months to years): Severe complications can include chronic arthritis (often in the knees), cognitive difficulties like memory loss, and inflammation of the brain or spinal cord.
Diagnosis and Treatment
#Diagnosis: Doctors often diagnose based on a combination of symptoms (like the classic rash) and history of tick exposure. While blood tests check for antibodies, they may not be accurate in the first few weeks after infection.
#Antibiotics: Standard treatment involves a course of oral antibiotics (like doxycycline or amoxicillin) for 10 to 28 days. Early treatment cures most cases rapidly and completely.Ongoing Symptoms: Some people experience lingering fatigue or aches after treatment, often called Post-Treatment Lyme Disease Syndrome (PTLDS).
Prevention and Immediate Action
#Tick Checks: After being outdoors in high-risk areas, check your skin (especially the hairline, armpits, and groin) and clothing for ticks.
#Safe Removal: If you find an attached tick, use fine-tipped tweezers to grasp it as close to the skin as possible and pull upwards steadily without twisting or crushing it.
#Seek Advice: Contact a healthcare provider like your GP or NHS 111 if you develop a rash or feel unwell after a tick bite.
