Lyme disease and other tick-borne diseases

Ticks in the United Kingdom can carry a number of infections which cause disease in both humans and animals. If left untreated, many of these infections can result in severe and debilitating symptoms. Early recognition of infection is most likely to occur if a patient is aware of the presence of disease, and can recognise the symptoms.

Physicians should be aware that many people diagnosed with tick-borne infections do not recall a tick bite. They should also be aware that infected ticks can be present in urban/suburban parks and gardens. Therefore a patient does not have to visit a recognised endemic area to contract a tick-borne disease. Additionally, ticks can carry a number of infections concurrently, which may result in several clinically similar infections being transmitted at once.

Tick-transmitted infections fall into several categories. Follow our "Quick links" or the links below for more details. In certain circumstances, doctors, employers, and the armed forces are required to report cases of these infections. Please see our "Disease Notification" section for detailed information.
