All attendees will have the choice of attending one of two concurrent tracks on Thursday:

We are offering a totally new Vector-Borne Illness (VBI) Fundamentals course for practitioners. This one day track is for medical professionals new to VBI diagnosis and treatment and for those veterans who want to brush up on their basics. In 2021 it was developed exclusively by the ILADS Medical Education Committee to prepare attendees for the unique ILADEF Physician Training ProgramTM. It gives specific step-by-step guidance using case discussions to exemplify real world experience. There will be ample opportunity to ask questions. This session is for medical professionals only. There are a limited number of grants available to reimburse the registration fee for first-time attending professionals. *Attending this course is the first step in a new Fellow Status for ILADS members.

We also are offering a day-long track called Clinical Pearls, which will offer practical advice for caring for your patients.

Friday, October 15 – Sunday, October 17:
