Travel-related infections are illnesses acquired during international or domestic travel, often linked to exposure to pathogens uncommon in the traveler’s home country. Common examples include malaria, dengue, chikungunya, Zika virus, and gastrointestinal infections. Risk factors depend on destination, duration of travel, and individual health status. Preventive measures such as vaccinations, prophylactic medications, safe food and water practices, and vector control are critical to reducing risks. Travel medicine services play a key role in educating travelers and ensuring early diagnosis upon return.
