But they can persist if treatment is started late. A few people with Lyme disease go on to develop long-term symptoms similar to those of fibromyalgia or chronic fatigue syndrome.This is known as post-infectious Lyme disease. Its not clear exactly why this happens. Its likely to be related to overactivity of your immune system rather than continued infection. How you get Lyme disease If a tick bites an animal carrying the bacteria that cause Lyme disease, the tick can become infected. The tick can then transfer the bacteria to a human by biting them. Ticks dont jump or fly. They climb on to your clothes or skin if you brush against something theyre on. They then bite into the skin and start to feed on your blood. Generally, youre more likely to become infected if the tick is attached to your skin for more than 24 hours. Ticks are very small and their bites are not painful, so you may not realise you have one attached to your skin. Where are ticks found? Ticks are found throughout the UK and in other parts of Europe and North America. There are a high number of ticks in the Scottish Highlands. They can be found in any areas with deep or overgrown plants where they have access to animals to feed on. Theyre common in woodland and moorland areas, but can also be found in gardens or parks. Whos at risk of Lyme disease? The risk of getting Lyme disease is higher: for people who spend time in woodland or moorland areas from March to October because more people take part in outdoor activities Its thought only a small proportion of ticks carry the bacteria that cause Lyme disease. Being bitten doesnt mean youll definitely be infected. However, its important to be aware of the risk and speak to a GP if you start to feel unwell. Diagnosing Lyme disease Diagnosing Lyme disease is often difficult as many of the symptoms are similar to other conditions. There are 2 kinds of blood test use to diagnose Lyme disease. The tests are not always accurate in the early stages of Lyme disease. So you may need tested more than once if you still have symptoms after a negative result. Treating Lyme disease If you have symptoms of Lyme disease, youll normally be given antibiotics . If youre prescribed antibiotics, its important you finish the course even if youre feeling better. Thisll help ensure all the bacteria are killed. If your symptoms are particularly severe, you may need antibiotic injections (intravenous antibiotics). Some of the antibiotics used to treat Lyme disease can make your skin more sensitive to sunlight. You should avoid prolonged exposure to the sun and not use sunbeds until after you have finished the treatment. Theres currently no agreement on the best treatment for post-infectious Lyme disease. This is because the underlying cause is not yet clear. Be wary of internet sites offering alternative diagnostic tests and treatments. These may not be supported by scientific evidence. Preventing Lyme disease Theres currently no vaccine available to prevent Lyme disease. The best way to prevent it is to adopt easy habits when youre in the countryside or near wildlife.
