Embedded ticks increase patient risk

This species secretes a paralysing toxin.

The paralysis takes a few days to develop.

It usually begins in the legs and then spreads up the body.

Therapeutic Guidelines: Toxicology and Wilderness says that, once the tick is removed, patients require observation and serial neurological examinations for 48 hours as the paralysis may continue to progress.

Although most patients need no specific treatment, severe cases may require life support. There is no antivenom.
