Lyme disease is a bacterial infection spread through the bite of an infected tick, most commonly found in wooded or grassy areas. Early symptoms often include a distinctive circular, expanding rash (sometimes described as a "bullseye"), along with flu-like symptoms such as fever, fatigue, and joint pain.

What is Lyme Disease?
Lyme disease is a bacterial infection spread through the bite of an infected tick, most commonly found in wooded or grassy areas. Early symptoms often include a distinctive circular, expanding rash (sometimes described as a "bullseye"), along with flu-like symptoms such as fever, fatigue, and joint pain.
Most cases of Lyme disease are effectively treated with antibiotics, particularly when started early, and prompt treatment significantly reduces the risk of the infection progressing to affect the joints, nervous system, or heart if left untreated.
02 · Understand
Clinical context
The rash doesn't always look like a classic bullseye
While often described as a bullseye pattern, the Lyme disease rash can vary in appearance, sometimes simply appearing as an expanding red or pink patch, which is worth knowing since not every case presents with the classic textbook look.

Practical steps
Remove Ticks Promptly and Correctly
If you find a tick attached to your skin, removing it promptly and correctly (using fine-tipped tweezers to grasp it close to the skin and pulling straight out) reduces the risk of infection being transmitted.
- 1Check for ticks after spending time in wooded or grassy areas.Prompt removal reduces the risk of infection transmission.
- 2Remove any attached tick correctly and promptly.Use fine-tipped tweezers, grasping close to the skin, and pull straight out without twisting.
- 3Watch for a rash or flu-like symptoms over the following weeks.These are the main early signs of Lyme disease to watch for after a tick bite.
- 4See a doctor promptly if you notice an expanding rash or relevant symptoms.Early antibiotic treatment is most effective and reduces the risk of complications.
- 5Wear long sleeves and trousers in tick-prone areas.This, along with insect repellent, helps reduce the risk of tick bites in the first place.

Prompt, correct tick removal and watching for a rash or flu-like symptoms afterward are key to catching Lyme disease early.
