Real-world example

Your doctor prescribes doxycycline as malaria prophylaxis for your trip to Mozambique. You start taking it 2 days before arrival and continue for 4 weeks after returning. The doxycycline doesn't treat malaria; it prevents the parasite from establishing itself in your body in the first place.

Why travellers need to know

Prophylaxis is the medical umbrella term for any preventive measure. For travellers, the most common forms are malaria prophylaxis (anti-malarial tablets), pre-exposure rabies vaccination, and altitude sickness prevention (acetazolamide). Understanding the term helps when doctors or travel clinics use it. Each prophylactic treatment has its own timing, duration, and side-effect profile.
