From the Guidelines
For travel medicine resources, I strongly recommend consulting the CDC's Travelers' Health website, the International Society of Travel Medicine (ISTM), and the WHO's International Travel and Health guide, as these are the most reliable and up-to-date sources of information 1. When it comes to travel medicine, it is essential to prioritize morbidity, mortality, and quality of life as the primary outcomes. To achieve this, travelers should take several precautions and prepare accordingly.
Pre-Travel Consultation
Before traveling, scheduling an appointment with a travel medicine specialist 4-6 weeks prior to departure is crucial for personalized advice. This consultation should cover essential medications, vaccinations, and travel health kits.
Essential Medications
Medications to consider include:
- Antimalarials (such as atovaquone/proguanil, doxycycline, or mefloquine depending on destination)
- Antibiotics for traveler's diarrhea (ciprofloxacin 500mg twice daily for 1-3 days or azithromycin 500mg daily for 1-3 days) 1
- Routine medications with extra supplies
Vaccinations
Vaccinations may include:
- Hepatitis A and B
- Typhoid
- Yellow fever
- Japanese encephalitis
- Rabies depending on the destination 1.
Travel Health Kits
Travel health kits should contain:
- Basic first aid supplies
- Insect repellent with 20-30% DEET
- Sunscreen
- Water purification tablets
- Anti-diarrheal medication like loperamide 1.
Preventive Measures
Preventive measures are crucial to prevent travel-related illnesses. These include:
- Avoiding contaminated food and water
- Using insect repellent and wearing protective clothing
- Avoiding direct contact with soil or sand in areas where fecal contamination is likely 1.
By following these recommendations and taking the necessary precautions, travelers can minimize their risk of illness and ensure a safe and healthy trip. It is essential to prioritize travel-related illnesses' prevention and treatment, as they can have a significant impact on morbidity, mortality, and quality of life 1.

From the Research
Resources for Travel Medicine
- Travelers can consult various resources for travel medicine, including primary care providers, specialized travel clinics, and online resources 2
- Primary care providers should be familiar with destination-specific disease risks, travel and routine vaccines, and be prepared to prescribe chemoprophylaxis and self-treatment regimens 2
- Travelers who require yellow fever vaccination, are immunocompromised, pregnant, or have multiple comorbid conditions may benefit from referral to a specialized travel clinic 2
Chemoprophylaxis Options
- Mefloquine is one of four antimalarial agents commonly recommended for preventing malaria in travelers to malaria-endemic areas 3
- The efficacy of mefloquine, chloroquine plus proguanil, and atovaquone plus proguanil in travelers from Denmark has been studied, with estimated efficacy rates of 1:2,232,1:599, and 1:1,943, respectively, for P. falciparum cases per prescription 4
- Mefloquine users were more likely to report adverse effects such as abnormal dreams, insomnia, anxiety, and depressed mood compared to atovaquone-proguanil users 3
Travel Health Advice
- Travel health advice is an important part of pre-travel consultations, but compliance with advice can be low, especially among younger travelers 5
- A study found that 67% of travelers claimed to have followed travel health advice, but still fell ill during travel to the same extent as those who did not 5
- Factors not easily influenced by the traveler, such as destination-specific disease risks, can play a role in travel-related illness 5
Malaria Prevention
- The risk of malaria infection in travelers varies by destination, with the highest risk in tropical Africa 4
- The use of chemoprophylaxis, such as mefloquine, can help prevent malaria, but breakthroughs can still occur 4
- Travelers should be aware of the risks of malaria and take necessary precautions, including using insecticide-treated bed nets and wearing protective clothing 6, 3
