← Back to Tick Myths and Facts
Does an infected tick always transmit its pathogen?
No. Detecting a pathogen in a tick does not prove it was transmitted during a particular bite; transmission depends on the pathogen, tick, attachment and other biological factors.

Key takeaways
Several steps must occur
The tick must be a competent vector, the pathogen must be present in a transmissible state and the feeding interaction must allow transfer. These conditions vary among tick-borne diseases.
Avoid false reassurance too
An untested or negative tick cannot rule out all risk, especially when the specimen, test panel or exposure history is incomplete. Use regional clinical guidance.
