Call emergency or public health services before going to a clinic or hospital.
Explain the possible exposure and symptoms so staff can prepare a safe assessment.
Avoid public transport and close contact with others while awaiting instructions.

Seek prompt assessment for eye pain, light sensitivity, reduced vision, new neurological symptoms, or a return of fever.
After recovery, arrange follow-up for persistent tiredness, joint pain, sleep problems, or difficulty returning to daily activities.
