Take your actual itinerary to a travel-health consultation. ‘Three weeks in Peru’ is less useful than overnight stops, activities and a possible jungle trip.
Gather vaccination records, medication details and relevant medical history. Note remote stays and planned exertion too. Ask what preparation fits your route, what to do if you become ill and when to seek help. Save your insurer's assistance contact and a medication list offline.
Arrange the consultation well before departure and revisit major itinerary changes afterwards.
Use it only to start the discussion. Have a qualified healthcare professional assess your health, age and precise destinations.
Ask about the planned activities, altitude, remote areas and medical evacuation. Save the answer; ‘worldwide cover’ does not settle those questions.
