Travelers can reduce malaria risk by taking prescribed prophylactic medicines before, during, and after travel, using effective mosquito repellents (DEET or picaridin), wearing long sleeves and pants, sleeping under treated mosquito nets, and staying in screened or air-conditioned rooms; if infected abroad, treatment is available at general hospitals, travel clinics, and facilities with infectious disease services, especially in endemic regions, and costs vary widely—USD 50–300 for outpatient diagnosis and medicines in many low-income countries, USD 500–3,000 for hospitalization, and USD 10,000+ if ICU care is needed—making early testing and prompt treatment critical to reduce complications and expenses.
