The pre-travel visit is where family physicians prevent that outcome by matching itinerary risk, psychiatric history, vaccine requirements, and realistic adherence counseling. Case Vignette: Four Weeks in Rural Ghana ---------------------------------------- A 28-year-old woman with well-controlled GAD on sertraline presents before volunteering at a community school in rural Ghana. She will stay in local housing, hike in forested areas on weekends, and has only routine childhood immunizations. Her question is pointed: “Which malaria pill will not make me feel terrible?” That anxiety is clinically useful; it forces a shared decision rather than a default prescription. Malaria Risk Stratification in Ghana ------------------------------------ This is a high-risk malaria itinerary for several reasons: - Ghana has malaria transmission in all areas, with *P. falciparum* predominating. - Rural housing increases exposure compared with screened, air-conditioned lodging. - Four weeks increases cumulative probability of an infectious bite. - Hiking and evening community activities increase vector contact. The pathophysiology matters for exams. *P. falciparum* causes severe disease through high parasitemia and microvascular sequestration. Conversely, *P. vivax* and *P. ovale* can relapse from dormant hepatic hypnozoites, which require primaquine or tafenoquine after documented normal quantitative G6PD testing. > **Clinical Pearl:** Chemoprophylaxis reduces malaria risk but is never complete protection. Fever after travel to a malaria-endemic area is malaria until proven otherwise, even if the patient took prophylaxis. Choosing Malaria Chemoprophylaxis --------------------------------- Mefloquine is the key trap in this case. It is contraindicated in patients with GAD and other major psychiatric disorders, so it should not be prescribed to this patient. Atovaquone-proguanil is a strong fit: short lead-in, short tail, generally favorable tolerability, and no psychiatric contraindication. Screen for pregnancy and severe renal impairment before prescribing. OptionBoard-relevant issueAtovaquone-proguanilDaily; start 1–2 days before; continue 7 days afterDoxycyclineDaily; photosensitivity, esophagitis; continue 4 weeks afterMefloquineAvoid with GAD, depression, psychosis, seizuresTafenoquineRequires quantitative G6PD; avoid in pregnancy For this patient, prescribe atovaquone-proguanil 250 mg/100 mg, one adult tablet orally once daily. Start 1–2 days before entering Ghana, take daily while there, and continue daily for 7 days after leaving the endemic area. Advise taking it with food or a milky drink at the same time each day. Vaccines: Required Versus Recommended ------------------------------------- Yellow fever vaccination is mandatory for entry into Ghana. The International Certificate of Vaccination or Prophylaxis becomes valid 10 days after primary vaccination and remains valid for life. Recommended vaccines should be individualized, but for this itinerary I would review: - Hepatitis A and typhoid for food and water exposure. - Hepatitis B if not immune or if medical, sexual, or blood exposure is possible. - MMR, Tdap, influenza, COVID-19, and polio status. - Meningococcal ACWY if traveling during dry season or to meningitis belt areas. Mosquito-Borne Disease Prevention Beyond Pills ---------------------------------------------- This counseling must cover malaria, dengue, chikungunya, Zika, and yellow fever. The patient should leave with a practical packing list, not vague advice. Counsel her to: - Use EPA-registered repellent such as DEET or picaridin on exposed skin. - Wear loose long sleeves and trousers, especially dusk to dawn. - Treat clothing, socks, boots, and bed nets with permethrin; do not apply permethrin to skin. - Sleep under an insecticide-treated net if rooms are unscreened or not air-conditioned. - Use screens, coils, or spatial repellents where appropriate. Ten Days After Return: Fever and Retro-Orbital Pain --------------------------------------------------- She returns 10 days after travel with fever 39.5°C, severe backache, myalgias, and retro-orbital pain. Dengue is the leading clinical diagnosis, especially with the “breakbone” pain phenotype. Still, malaria must be ruled out urgently. The differential for fever after Ghana includes: - Malaria, particularly *P. falciparum*. - Dengue or other arboviruses. - Enteric fever. - Rickettsial infection or leptospirosis. - Acute HIV, viral hepatitis, influenza, COVID-19, and common bacterial infection. - Viral hemorrhagic fever only if exposure history and timing support it. Initial evaluation should assess hemodynamics, mental status, bleeding, pregnancy status, hydration, and travel exposures. First-line screening includes thick and thin blood films or rapid malaria testing, CBC/FBE, and LFTs. In practice, add electrolytes, creatinine, glucose, blood cultures when enteric fever is plausible, and dengue testing based on illness day. If dengue is suspected, treat supportively with oral or IV fluids as indicated and acetaminophen for fever. Avoid aspirin and NSAIDs because of bleeding risk. Warning signs such as abdominal pain, persistent vomiting, mucosal bleeding, lethargy, fluid accumulation, rising hematocrit, or falling platelets warrant escalation or admission. Clinical Application in Family Medicine --------------------------------------- The best pre-travel visit is structured but not robotic: 1. Define destination, rurality, season, lodging, activities, and duration. 2. Screen pregnancy, renal disease, psychiatric history, seizures, G6PD risk, and medication adherence barriers. 3. Separate required vaccines from recommended vaccines. 4. Prescribe prophylaxis with exact start and stop dates. 5. Give a fever-after-return safety-net plan. For anxious travelers, normalize concern about adverse effects and offer a written plan. In my experience, adherence improves when patients understand that missed doses after return still matter. Key Points for Board Exams -------------------------- - Rural Ghana travel is high risk for *P. falciparum* malaria. - Mefloquine is contraindicated in this patient because of GAD. - Atovaquone-proguanil is taken daily with food, starting 1–2 days before travel and continuing 7 days after departure. - Yellow fever vaccination is required for Ghana; the certificate is valid from day 10 for life. - Dengue classically causes fever, severe myalgia, and retro-orbital pain, but malaria must be excluded in any febrile returned traveler. - Primaquine or tafenoquine targets *P. vivax* and *P. ovale* hypnozoites, only after normal G6PD testing. Conclusion ---------- This case rewards disciplined travel medicine reasoning. The winning answer is not simply “give malaria pills”; it is to avoid mefloquine, prescribe atovaquone-proguanil correctly, document yellow fever vaccination, reinforce mosquito avoidance, and treat post-travel fever as time-sensitive until malaria is excluded. Frequently Asked Questions ---------------------------- ### Why is mefloquine inappropriate for this traveler? Mefloquine is contraindicated in patients with generalized anxiety disorder and other significant psychiatric conditions, so an alternative such as atovaquone-proguanil is preferred. ### When should atovaquone-proguanil be started and stopped? Start 1–2 days before entering the malaria-endemic area, take it daily during travel, and continue for 7 days after leaving. Take it with food or a milky drink. ### What vaccine documentation is required for Ghana entry? Travelers need proof of yellow fever vaccination on an International Certificate of Vaccination or Prophylaxis. It is valid beginning 10 days after primary vaccination and remains valid for life. ### Why must malaria be tested even when dengue seems likely? Dengue can fit the fever, retro-orbital pain, and severe myalgia pattern, but *P. falciparum* malaria can progress rapidly and prophylaxis does not fully exclude infection. ### What test prevents unsafe use of primaquine or tafenoquine? A quantitative G6PD level is required before using primaquine or tafenoquine because these drugs can cause hemolysis in G6PD deficiency. References (5) ------------------ 1. 1.
