Australian paralysis ticks

The Australian paralysis tick contains a toxin in its saliva that may induce progressive paralysis in humans. This is caused by interference with presynaptic transmission in motor nerves. Some individuals may also develop a severe allergy to the venom.

First Aid First aid consists of finding and removing the tick, then supporting the patient until antivenom can be administered. The tick should be levered out using a pair of curved scissors. If the patient is already ill, the pressure-immobilisation procedure should be used where possible to inhibit the movement of any toxic saliva which may have been expressed during the removal of the tick. NB. Check carefully for other attached ticks.

Medical Treatment and Administration of Antivenom Supportive care, including supplemental oxygen and occasionally mechanical ventilation may be required. Less severe cases may only require removal of the tick and observation, as symptoms will not necessarily abate after its removal. For severe cases, tick antivenom may be given intravenously.
