Overview
A vector-borne (results from an infection transmitted to humans and other animals by blood-feeding arthropods such as mosquitoes, ticks, and fleas) disease characterized by four specific species of bacteria, including Borrelia burgdorferi, Borrelia mayonii, Borrelia afzelii, and Borrelia garinii. The most common way for the condition to be transmitted is via the bite of infected black-legged ticks (deer ticks).
