Can ticks transmit different diseases in different parts of the world?

Yes. Tick species and the pathogens they can carry differ by region, so the diseases considered after a bite depend partly on where exposure occurred.

Short answer

Yes. Tick species and the pathogens they can carry differ by region, so the diseases considered after a bite depend partly on where exposure occurred.

At a glance

Lyme borreliosis is only one tick-borne disease. Public-health authorities also monitor illnesses including tick-borne encephalitis, relapsing fever, rickettsial diseases, tularemia and Crimean-Congo haemorrhagic fever in relevant regions.

Key takeaways

• Location is important when assessing exposure.

• A disease present in one region may be absent or rare in another.

• Use destination-specific advice before travel and local medical advice afterwards.

Regional risk matters

Ticks are a diverse group, and different species occur in different environments. The pathogens associated with them also vary. A worldwide resource should therefore show the region and date attached to its guidance.

For travellers

Check current official travel-health information before visiting tick habitat. If you become unwell, tell a healthcare professional where and when you travelled and about any known or possible tick exposure.
