How Does a Tick Transmit Disease?

Ticks transmit diseases during feeding. The tick has special piercing-sucking mouthparts designed to penetrate the host’s skin and extract blood. During the feeding process, the tick will excrete a ‘pathogen’ through its saliva that helps to prevent the host’s blood from clotting. It also acts as an anesthetic, suppressing the host’s immediate immune response. It is during this action that the chance of disease passing from the tick to the host occurs.
