First, read the text below. Then listen to the audio file. Finally, make questions of your own:

Example chat (you = traveler, doc = travel clinic)

you: Hi—traveling to Peru for 10 days in August; hiking above 3,500 m. I’m 34, healthy, on combined birth control. Any vaccines or meds recommended?

doc: Hi—great details. For Peru: ensure your routine vaccines are up to date (MMR, Tdap). Consider Hep A and typhoid. For high-altitude trekking, acetazolamide can help—do you have any sulfa allergies? Continue birth control; bring extra supply. Use insect repellent at dusk; malaria risk is low in most tourist areas but let me know exact regions.

you: No sulfa allergy. How soon before travel should I start acetazolamide?

doc: Start 24–48 hours before ascent and continue for 48 hours after descent; typical dose 125 mg twice daily. I’ll send a prescription and vaccine clinic appointments.
