Key facts

  • Malaria is a mosquito-borne infection caused by Plasmodium parasites, common across many tropical regions.
  • Prophylaxis means taking a medicine before, during, and after travel to a risk area so that any parasites picked up from a bite are cleared before they cause disease.
  • Doxycycline, from the antibiotics class, is widely used and particularly relevant where chloroquine-resistant strains circulate.
  • Mosquito precautions, repellent, long sleeves at dusk, and treated nets, should run alongside any medicine.

Choosing and timing your cover

The right medicine depends on your destination, trip length, and personal health history. Doxycycline is widely used for malaria prevention and is particularly relevant in areas where chloroquine-resistant strains circulate. It belongs to the antibiotics class and works by blocking parasite development inside red blood cells.

Timing matters: doxycycline is typically started one to two days before entering a risk area and continued for four weeks after leaving. Missing doses significantly reduces protection, so a consistent daily routine is essential throughout the trip.

Precautions alongside medicine

Mosquito precautions should run alongside any medicine. Repellent, long sleeves at dusk, and insecticide-treated nets all reduce bite exposure and make prophylaxis more effective. No preventive medicine is completely foolproof, so avoiding bites in the first place adds an important extra layer of protection.

Who needs to plan ahead

Travellers with certain medical conditions, those who are pregnant, and young children may need a different medicine or extra precautions, so it is worth checking well before departure rather than at the last minute. Starting the chosen medicine on schedule, before entering the risk area rather than after arrival, gives it time to reach an effective level in the body and gives you the chance to notice and address any side effects before travel begins.

After you return

Continuing the medicine for the full period after leaving a risk area matters just as much as starting it on time, since parasites picked up near the end of a trip can still be developing in the body after you get home. Report any fever in the weeks following travel to a doctor and mention where you have been, even if you took prophylaxis correctly, since no preventive regimen offers complete protection.
