Ensure your travels are memorable for the right reasons with these common tips on avoiding mosquitoes and dengue fever.


Health preparation:

  3. Documentation: It is advisable to carry a copy of your prescriptions, a letter from your doctor, and translations of any medical documents.5


  4. If you need to take prescription medications with you for existing conditions: Ensure you have enough for your trip and check the rules for all the countries you're going to.
