Ticks are blood-sucking parasites. When they take a blood meal, they can cause dermatological disease directly by their bite, or indirectly as vectors of other diseases.
Tick-borne diseases include:
- Bacterial infections including Lyme disease, relapsing fever, tularaemia, and babesiosis
- Rickettsial infections including Rocky Mountain spotted fever, other spotted fevers, ehrlichiosis and anaplasmosis, and Q fever
- Viral diseases including tick-borne encephalitis, Crimean-Congo haemorrhagic fever, Colorado tick fever, Powassan encephalitis, and others
- Tick bite induced red meat allergy.
