Short answer

Seek prompt medical advice if you develop an expanding rash, fever, severe headache, unusual fatigue, facial weakness, neurological symptoms or other concerning illness after possible tick exposure.

At a glance

Urgency depends on the symptoms, where exposure occurred and individual risk; severe or rapidly worsening illness needs urgent care.

Key takeaways

• Do not wait for a bullseye rash.

• Share the date and place of exposure.

• Use emergency services for severe symptoms.

Symptoms matter more than finding the tick

A bite may go unnoticed, and different tick-borne diseases have different early signs. Tell the clinician about outdoor activity, travel, pets and the approximate symptom timeline.

Follow local pathways

Disease distribution and recommended testing vary between countries. Use current public-health guidance for the place where exposure occurred and the healthcare system providing care.
