  • Can I prevent getting tick-borne encephalitis?

    You can take the following precautions to help reduce your risk of infection:

    • Visit your nearest convenient pharmacy or specialist travel health clinic for a risk assessment before your trip
    • Avoid places – like long grass – where ticks live2,3
    • Use a recommended insect repellent containing either Picaridin, DEET, PMD or OLE (oil of lemon eucalyptus), IR3535 or 2-undecanone3
    • Wear appropriate clothing (e.g long-sleeved clothes, long trousers, socks and shoes) to minimise exposed skin3
    • Check every day for ticks that may have attached themselves to your body.3 Carefully remove any that you find using a tick remover or tweezers. Gently grip the tick as close to the skin as possible and pull it upwards without twisting or crushing. Then wash your skin with water and soap and apply an antiseptic cream.2
