When you subscribe to the continuous follow-up you will receive a monthly reminder e-mail asking you to report a tick bite (or bites) or an erythema migrans that has occurred in the past month on the website. If you have nothing to report it is sufficient to click on "nothing to report" in the e-mail itself. For a good analysis of the results, it is important that you participate regularly. All tick bite and erythema migrans reports will appear on a personal user page that you can access in your profile on the website.
