Official title

Evaluation and Follow-up of Patients With Tick-borne Diseases

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: Lyme disease is the most common tick-borne disease in the United States, but other diseases transmitted by ticks have also been on the rise in recent years. Early symptoms of a tickborne disease include fever, headache, fatigue and possible rash. Researchers want to collect information and samples from people with Lyme disease and other tick-borne illnesses to better understand and diagnose these diseases. Objective: To evaluate and follow people with tick-borne diseases to help researchers learn more about these infections. Eligibility: People ages 18 and older who have or are suspected of having a tick-borne infection. Design: Participants will have an initial visit, and visits about 1, 6, and 12 months later. The visits can include a physical exam, blood tests, collection of blood, urine and saliva samples for research, and filling out health-related questionnaires. Participants who have the rash of Lyme disease may be invited to have up to 3 skin punch biopsies of the rash for research.
