Basics – Other Tick-Borne Diseases

Q. Are there other co-infections?
Q. Are there other co-infections?

A. New tick-borne diseases are being discovered all the time, and some established diseases are being diagnosed more often. New Borrelia species including Borrelia miyomotoi and Borrelia mayonii are emerging diseases that cause somewhat different symptoms than Lyme disease. Southern Tick-Associated Rash Illness (STARI) seems to share many symptoms with Lyme disease but it may be caused by a different Borrelia species. Colorado Tick Fever, Heartland Virus, and Powassan Virus are caused by viruses and not bacteria. Powassan Virus, which is fatal for a significant number of patients, is carried by deer ticks and can be transmitted after only 15 minutes of tick attachment. There is no treatment, and those who survive usually suffer from long-term, serious neurological damage. Powassan Virus is relatively rare compared to the other tick-borne diseases.
