Tick-borne diseases

Some ticks in Tasmania can cause illness, including Rickettsial infections, allergic reactions, paralysis and a mammalian meat allergy. 

Summary

Rickettsial infection is a notifiable disease in Tasmania. Refer to the Guidelines for Notifying Diseases and Food Contaminants.

Rickettsial infections of significance in Tasmania include Flinders Island Spotted Fever.  This is an illness caused by bacteria known as Rickettsia honei.

Other Rickettsial infections of importance in Australia include Rickettsia australis (Queensland tick typhus, spotted fever), Orientia tsutsugamushi (scrub typhus) and R. typhi (murine typhus). Other tick-borne illnesses of national significance include Q fever. 

Protect yourself

There is a vaccine for Q fever. There are no vaccines available for other tick-borne illnesses that you may get in Australia. 

Strategies to prevent tick bites on people and pets are key in reducing tick-borne illness. 

• Avoid tick infested/endemic areas and contact with ticks
• Wear appropriate light-coloured protective clothing
• Treat clothing and gear with the insecticide permethrin
• Use insect repellent, including those containing picardin, DEET (Diethyl toluamide) or oil of lemon eucalyptus on exposed skin. Always read the manufacturer's instructions before applying 
• Use camp beds when camping to elevate the body above the ground
• Check clothing for ticks, then place in a hot dryer for 20 minutes, if available, to kill ticks
• Check the body for ticks when you come inside. 

Removing a tick

• First, establish if a person is allergic to ticks or not.
• If the person IS allergic to ticks, do not disturb the tick and seek urgent medical assistance at the nearest emergency department or call triple zero (000). Ensure their adrenaline autoinjector (EpiPen or AnaPen) is available in case it is needed. 
• If the person is NOT allergic, and the tick is easily visible, kill the tick as soon as possible by freezing it with an ether-containing spray. Ether-containing sprays are available at pharmacies. If the tick does not drop off after following the instructions on the spray, leave the tick in place and seek medical assistance.
• Never forcibly remove a tick. 
• DO NOT use household tweezers to remove a tick, do not jerk or twist the tick. Don't use methylated spirits, kerosene, petroleum jelly, nail polish, oil, alcohol or a lighted match. 
• See a doctor if unable to kill a tick or if any part of the tick is left in the skin.
