Lyme disease is spread **through biological vectors**.

### Explanation
Lyme disease is primarily transmitted to humans through the bite of infected ticks, specifically the black-legged tick (Ixodes scapularis) in the northeastern and north-central United States and the western black-legged tick (Ixodes pacificus) on the West Coast. These ticks feed on the blood of various animals, including deer and mice, which can carry the bacteria *Borrelia burgdorferi*, responsible for Lyme disease. When an infected tick bites a human, the bacteria can be introduced into the bloodstream, leading to infection. It is important to note that Lyme disease is not spread through contaminated objects, airborne particles, or mechanical vectors in the way some other diseases might be, highlighting the specificity of its transmission routes.
